Page 15: About The Command Line Interface

For additional information, see the hardware and software manuals that shipped with your system. NOTE: Always check for updates on support.dell.com and read the updates first because they often supersede information in other documents. NOTE: CLI commands do not have interactive warnings for destructive commands.
Page 16: How To Use The Command Line Interface

You can use the command line interface to perform the following functions: • Directly access the script engine and run commands in interactive mode or using a script file. • Create script command batch files to be run on multiple storage arrays when you need to install the same configuration on different storage arrays.
Page 17: Usage Notes

The following syntax is the general form of a CLI command: SMcli storageArray parameters script-commands; where, SMcli invokes the command line interface storageArray is the host name or IP address of the storage array parameters are the CLI parameters that define the environment and purpose of the command script-commands are the commands or name of the script file containing the script commands...
Page 18: Cli Commands

CLI Commands This section lists the CLI commands you can use to perform the following functions: • Identify storage arrays • Set passwords • Add storage arrays • Specify communication parameters • Enter individual script configuration commands • Specify a file containing script configuration commands The following are general forms of the CLI commands, showing the parameters and terminals used in each command.

Page 26: Formatting Considerations

Formatting Considerations Quotation marks (" ") used as part of a name or label require special consideration when you run the CLI and script commands on a Microsoft Windows operating system. The following explains the use of quotation marks in names while running CLI and script commands on Windows. When quotation marks ("...
Page 27: Exit Status

When the CLI encounters either type of error, it writes information describing the error directly to the command line and sets a return code. Depending on the return code, the CLI might also write additional information about which parameter caused the error. The CLI also writes information about what command syntax was expected to help you identify any syntax errors you might have entered.
Page 28

(continued) Table 1-3. Exit Status Status Value Meaning The storage array name was not in the configuration file. A management class does not exist for the storage array. A storage array was not found in the configuration file. An internal error occurred. Invalid script syntax was found.
Page 29: Usage Examples

Usage Examples The following examples show how to enter CLI commands on a command line. The examples show the syntax, form, and, in some examples, script commands. Examples are shown for both Windows and Linux operating systems. The usage for the -c parameter varies depending on your operating system.

Page 31: About The Script Commands

About the Script Commands You can use the script commands to configure and manage a storage array. The script commands are distinct from the command line interface (CLI) commands; however, you enter the script commands using the command line interface. You can enter individual script commands, or run a file of script commands.

NOTE: You can use any combination of alphanumeric characters, hyphens, and underscores for the names. Command names can have a maximum of 30 characters. If you exceed the maximum character limit, replace square brackets ([ ]) with angle brackets (< >) to overcome this limitation. Use an object type when the command is not referencing a specific object.
Page 34: Script Command Synopsis

Statement data is in the form of attribute=value (such as raidLevel=5), an attribute name (such as batteryInstallDate), or an operation name (such as consistencyCheck). Script Command Synopsis Because you can use the script commands to define and manage the different aspects of a storage array (such as host topology, physical disk configuration, RAID controller module configuration, virtual disk definitions, and disk group definitions), the actual number of commands is extensive.

Page 45: Configuring A Storage Array

Configuring a Storage Array This chapter explains how to run script commands from the command line to create a virtual disk from a group of physical disks and how to configure a redundant array of independent disks (RAID) storage array. This chapter assumes that you understand basic RAID concepts and terminology.

client>smcli 123.45.67.89 -c "save storageArray configuration file= \"c:\folder\storageArrayconfig1.scr\";" In this example, the name folder is the folder in which you choose to place the configuration file, and storageArrayconfig1.scr is the name of the file. Choose any folder and any file name. MD Storage Manager uses the file extension .scr when it creates the configuration file.
Page 51

The userLabel parameter is the name to give to the virtual disk. The virtual disk name can be any combination of alphanumeric characters, hyphens, and underscores. The maximum length of the virtual disk name is 30 characters. Spaces are not allowed. You must put quotation marks (" ") around the virtual disk name.
Page 52

Because only 20 GB are assigned to the virtual disk, 199 GB remain available for other virtual disks that you can later add to this disk group. The segment size for each virtual disk is 64 KB. Hot spares have not been created for this new disk group.
Page 53

Example of Creating Virtual Disks with Software-Assigned Physical Disks client>smcli 123.45.67.89 -c "create virtualDisk physicalDiskCount=3 raidLevel=5 userLabel= \"Engineering_1"\ capacity=20 GB owner=0 segmentSize=64;" The command in this example creates the same virtual disk as the previous create virtualDisk command, however, in this case the user does not know which physical disks are assigned to this disk group.
Page 54: Using The Auto Configure Command

Enclosure Loss Protection The enclosureLossProtect parameter is a boolean switch that turns enclosure loss protection on or off. To work properly, each physical disk in a virtual disk group must be in a separate enclosure. Enclosure loss protection is set under the following conditions: •...
Page 55

• Number of physical disks in a disk group • Number of disk groups • Number of virtual disks in each disk group • Number of hot spares • Size of each segment on the physical disks After defining these parameters, the MD Storage Manager automatically creates the disk groups, virtual disks, and hot spares.
Page 56

When you use the autoConfigure storageArray command without specifying the number of disk groups, the firmware determines how many virtual disks and disk groups to create. The firmware creates one disk group and one virtual disk up to the maximum number that the storage array can support. When you specify the number of disk groups, the firmware creates only that number of disk groups.
Page 57: Modifying Your Configuration

For optimal performance in a multi-user database or file system storage environment, set the segment size to minimize the number of physical disks needed to satisfy an I/O request. Using a single physical disk for a single request leaves other physical disks available to simultaneously service other requests.
Page 58: Setting The Storage Array Password

• Storage array host type • Global hot spares NOTE: Before modifying your configuration, save a copy of your current configuration to a file (see "Saving a Configuration to a File" on page 49). If you have problems with your modifications, you can use the information in the file to restore your previous configuration.

Page 60: Setting Modification Priority

The defaultHostType parameter defines how the RAID controller modules communicate with the operating system on undefined hosts connected to the storage array. This parameter defines the host type only for storage array data I/O activities; it does not define the host type for the management station. The operating system can be Windows or Linux.
Page 61: Assigning Global Hot Spares

• Initialization • Changing segment size • Defragmentation of a disk group • Adding free capacity to a disk group • Changing the RAID level of a disk group The lowest priority rate favors system performance, but the modification operation takes longer. The highest priority rate favors the modification operation, but the system performance might be degraded.
Page 62

You can assign or unassign global hot spares by using the set physicalDisk command. To use this command, you must perform these steps: 1 Identify the location of the physical disks by enclosure ID and slot ID. 2 Set the hotSpare parameter to TRUE to enable the hot spare or FALSE to disable an existing hot spare.

See step 1 through step 4 in the preceding section, "Preparing Host Servers to Create an Initial Snapshot Virtual Disk" on page 67. The following example shows a command in which users assign the physical disks: client>smcli 123.45.67.89 -c "create snapshotVirtualDisk sourceVirtualDisk= \"Mars_Spirit_4\"...
Page 70: Creating A Snapshot Virtual Disk With Software-assigned Physical Disks

Creating a Snapshot Virtual Disk with Software-Assigned Physical Disks This version of the create snapshotVirtualDisk command lets you choose an existing disk group in which to place the snapshot repository virtual disk. The storage management software determines which physical disks to use. You can also define how much space to assign to the repository virtual disk.
Page 71: Creating A Snapshot Virtual Disk By Specifying A Number Of Physical Disks

Define the capacity of a snapshot repository virtual disk as any percentage of the size of the source virtual disk. A value of 20 percent is a good compromise between size and speed. In the previous example, the size of the snapshot repository is set to 4 GB.
Page 72: User-defined Parameters

The command in this example creates a new snapshot repository virtual disk that consists of three physical disks. The three physical disks comprise a new disk group with a RAID level of 5. This command also takes a snapshot of the source virtual disk, which starts the copy-on-write operation.
Page 73

(continued) Table 4-3. Snapshot Virtual Disk Parameters Parameter Description userLabel Specifies the name to give to the snapshot virtual disk. If you do not choose a name for the snapshot virtual disk, the RAID controller modules create a default name using the source virtual disk name. For example, if the source virtual disk name is Mars_Spirit_4 and it does not have a snapshot virtual disk, the default snapshot virtual disk name is Mars_Spirit_4-1.
Page 74: Names Of Snapshot Virtual Disks And Repository Virtual Disks

The following example of the create snapshotVirtualDisk command includes user-defined parameters: client>smcli 123.45.67.89 -c "create snapshotVirtualDisk sourceVirtualDisk= \"Mars_Spirit_4\" repositoryRAIDLevel=5 repositoryPhysicalDiskCount=5 physicalDiskType= SAS userLabel=\"Mars_Spirit_4_snap1\" repositoryUserLabel=\"Mars_Spirit_4_rep1\" warningThresholdPercent=75 repositoryPercentOfSource=40 repositoryFullPolicy=failSnapShot;" The following example is the script file version of the command: create snapshotVirtualDisk sourceVirtualDisk= "Mars_Spirit_4"...

name Engineering Data, the snapshot virtual disk can have a name Engineering Data-S1. The repository virtual disk can have a name of Engineering Data-R1. If you do not choose a unique name for either the snapshot virtual disk or repository virtual disk, the RAID controller modules create a default name by using the name of the source virtual disk.
Page 76: Stopping And Deleting A Snapshot Virtual Disk

The following example is the script file version of the command: set virtualDisk ["Mars_Spirit_4-1"] userLabel= "Mars_Odyssey_3-2"; When you change the warning threshold percent and repository full policy, you can apply the changes to one or several snapshot virtual disks. The following example uses the set (snapshot) virtualDisk command to change these properties on more than one snapshot virtual disk: client>smcli 123.45.67.89 -c "set virtualDisks...
Page 77: Re-creating The Snapshot Virtual Disk

When you stop the copy-on-write operations for a specific snapshot virtual disk, only that snapshot virtual disk is disabled. All other snapshot virtual disks remain in operation. Re-creating the Snapshot Virtual Disk To restart a copy-on-write operation, use the recreate snapshot virtualDisk command.

See "SMrepassist Utility" in the Owner’s Manual for more information. 3 Remove the drive letter(s) of the source and (if mounted) snapshot virtual disk in Windows or unmount the virtual drive(s) in Linux to help guarantee a stable copy of the drive for the Snapshot.
Page 79: Using The Virtual Disk Copy Feature

If you ordered Premium Features for Virtual Disk Copy, you received a Premium Features Activation card shipped in the same box as your Dell PowerVault MD storage array. Follow the directions on the card to obtain a key file and to enable the feature.
Page 80: Creating A Virtual Disk Copy

Table 5-1 lists the Virtual Disk Copy commands and briefly describes what the commands do. Table 5-1. Virtual Disk Copy Commands Command Description create virtualDiskCopy Creates a virtual disk copy and starts the virtual disk copy operation. disable storageArray Turns off the current virtual disk copy operation. feature=virtualDiskCopy enable storageArray feature Activates the Virtual Disk Copy feature.
Page 81: Enabling The Virtual Disk Copy Feature

The following steps show the general process for creating a virtual disk copy: 1 Enable the Virtual Disk Copy feature. 2 Determine candidates for a virtual disk copy. 3 Create the target virtual disk and source virtual disk for a virtual disk copy. Enabling the Virtual Disk Copy Feature The first step in creating a virtual disk copy is to make sure the feature is enabled on the storage array.
Page 82: Creating A Virtual Disk Copy

Creating a Virtual Disk Copy CAUTION: A virtual disk copy overwrites data on the target virtual disk. Ensure that you no longer need the data or have backed up the data on the target virtual disk before starting a virtual disk copy. When you create a virtual disk copy, you must define which virtual disks to use for the source virtual disk and target virtual disks.
Page 83: Copying The Virtual Disk

3 Remove the drive letter(s) of the source and (if mounted) virtual disk in Windows or unmount the virtual drive(s) in Linux to help guarantee a stable copy of the drive for the virtual disk. If this is not done, the copy operation reports that it has completed successfully, but the copied data is not updated properly.
Page 84: Viewing Virtual Disk Copy Properties

The create virtualDiskCopy command might look like the following example: client>smcli 123.45.67.89 -c "create virtualDiskcopy source=\"Jaba_Hut\" target= \"Obi_1\" copyPriority=medium targetreadonlyenabled=true" The command in this example copies the data from the source virtual disk named Jaba_Hut to the target virtual disk named Obi_1. Setting the copy priority to medium provides a compromise between the following storage array operations: •...
Page 85: Changing Virtual Disk Copy Settings

• The completion timestamp • The virtual disk copy priority • The read-only attribute setting for the target virtual disk • The source virtual disk World Wide Identifier (WWID) or the target virtual disk WWID A virtual disk can be a source virtual disk for one virtual disk copy and a target virtual disk for another virtual disk copy.
Page 86

Copy priority has five relative settings, which range from highest to lowest. The highest priority supports the virtual disk copy, but I/O activity might be affected. The lowest priority supports I/O activity, but the virtual disk copy takes longer. You can change the copy priority at three different times in the operation: •...
Page 87: Recopying A Virtual Disk

The following example shows how to change parameters using the set virtualDiskCopy command: client>smcli 123.45.67.89 -c "set virtualDiskcopy target [\"Obi_1\"] copyPriority=highest targetreadonlyenabled=false;" The following example is the script file version of the command: set virtualDiskcopy target ["Obi_1"] copyPriority= highest targetreadonlyenabled=false; Recopying a Virtual Disk CAUTION: The recopy virtualDiskCopy command overwrites existing data on the...
Page 88: Recopying The Virtual Disk

NOTE: Removing the drive letter of the associated virtual disk(s) in Windows or unmounting the virtual drive in Linux helps to guarantee a stable copy of the drive for the virtual disk copy. Before creating a new virtual disk copy for an existing copy pair, both the server and the associated virtual disk you are recopying have to be in the proper state.
Page 89: Stopping A Virtual Disk Copy

NOTE: Use one or all of the optional parameters as needed to help define your configuration. It is not necessary to use any optional parameters. Refer to steps 1 through 4 in the preceding section, "Preparing Host Servers to Recopy a Virtual Disk" on page 87. The following example shows a command that changes the copy priority: client>smcli 123.45.67.89 -c "recopy virtualDiskCopy target [\"Obi_1\"] copyPriority=...
Page 90: Removing Copy Pairs

client>smcli 123.45.67.89 -c "stop virtualDiskCopy target [\"Obi_1\"];" The following example is the script file version of the command: stop virtualDiskCopy target ["Obi_1"]; Removing Copy Pairs The remove virtualDiskCopy command enables you to remove a virtual disk copy pair from the storage array configuration. All virtual disk copy information for the source virtual disk and target virtual disk is removed from the storage array configuration.
Page 91: Storage Partitioning

When running the Virtual Disk Copy feature with other features, you must take the requirements of other features into consideration to ensure you set up a stable storage array configuration. You can also run the Virtual Disk Copy feature while running Dynamic Virtual Disk Expansion. Storage Partitioning Storage partitioning enables hosts to share access to virtual disks in a storage array.
Page 92

Creating a snapshot virtual disk automatically creates a snapshot repository virtual disk. The snapshot repository virtual disk stores information about the data that has changed since the snapshot virtual disk was created. Snapshot repository virtual disks cannot be selected as a source virtual disk or target virtual disk in a virtual disk copy.
Page 93: Using The Remote Replication

Using the Remote Replication Premium Feature The Remote Replication premium feature provides for online, real-time replication of data between storage arrays over a remote distance. In the event of a disaster or a catastrophic failure on one storage array, you can promote the second storage array to take over responsibility for computing services.
Page 94: How Remote Replication Works

How Remote Replication Works When you create a remote replicated pair, the remote replicated pair consists of a primary virtual disk on a local storage array and a secondary virtual disk on a storage array at another site. A standard virtual disk might only be included in one replicated virtual disk pair.
Page 95: Replication Relationships

When you activate the Remote Replication premium feature on the storage array, you create two replication repository virtual disks, one for each RAID controller module in the storage array. An individual replication repository virtual disk is not needed for each remote replication. When you create the replication repository virtual disks, you specify the location of the virtual disks.
Page 96

between the storage arrays that are participating in Remote Replication. This section also describes the actions taken by the RAID controller module owner of the primary virtual disk if a link interruption occurs between storage arrays. Write Modes When the RAID controller module owner of the primary virtual disk receives a write request from a host, the RAID controller module first logs information about the write to a replication repository virtual disk, and then writes the data to the primary virtual disk.
Page 97: Link Interruptions Or Secondary Virtual Disk Errors

When using Asynchronous write mode, write requests are not guaranteed to be completed in the same order on the secondary virtual disk as they are on the primary virtual disk. If the order of write requests is not retained, data on the secondary virtual disk might become inconsistent with the data on the primary virtual disk.
Page 98: Resynchronization

the secondary virtual disk. After the resynchronization starts, the replicated pair transitions from an Unsynchronized status to a Synchronization in Progress status. The primary RAID controller module also marks the replicated pair as unsynchronized when a virtual disk error on the secondary side prevents the remote write from completing.
Page 99: Creating A Remote Replicated Pair

CAUTION: Possible loss of data access – Any communication disruptions between the primary storage array and the secondary storage array while resynchronization is underway could result in a mix of new data and old data on the secondary virtual disk. This condition would render the data unusable in a disaster recovery situation.
Page 100: Performance Considerations

Performance Considerations Keep these performance considerations in mind when you create replication relationships: • The RAID controller module owner of a primary virtual disk performs a full synchronization in the background while processing local I/O writes to the primary virtual disk and associated remote writes to the secondary virtual disk.
Page 101: Enabling The Remote Replication Premium Feature

Enabling the Remote Replication Premium Feature The first step in creating a remote replication is to make sure that the Remote Replication premium feature is enabled on both storage arrays. Because Remote Replication is a premium feature, you need a feature key file to enable the premium feature.

The RAID level that you choose for the replication repository virtual disk has these constraints: • RAID Level 0 – You cannot use RAID Level 0. • RAID Level 1 – The number of physical disks must be an even number. If you select an odd number of physical disks, the RAID controller module firmware returns an error.

the secondary virtual disk name, and the remote storage array name (or WWID) are the minimum information that you need to provide. Using this command, you can also define synchronization priority, write order, and write mode. The command takes this form: create remoteReplication primary= “primaryVirtualDiskName”...
Page 107: Changing Remote Replication Settings

Setting the write mode to synchronous and the synchronization priority to highest means that host write requests are written to the primary virtual disk and then immediately copied to the secondary virtual disk. These actions help to make sure that the data on the secondary virtual disk is as accurate a copy of the data on the primary virtual disk as possible.
Page 108: Suspending And Resuming A Replication Relationship

-c “set remoteReplication localVirtualDisk [Jan_04_Account] syncPriority=medium writeOrder=notpreserved writeMode=asynchronous;” This example shows how to use the command in a script file: set remoteReplication localVirtualDisk [Jan_04_Account] syncPriority=medium writeOrder=notpreserved writeMode=asynchronous; Suspending and Resuming a Replication Relationship Use the suspend remoteReplication command to stop data transfer between a primary virtual disk and a secondary virtual disk in a replication relationship without disabling the replication relationship.
Page 109

NOTE: If you suspend a remote replication that is set up in the Write consistency mode, you suspend all remote replicated pairs within the group. You can then resume replication operations for any of the individual remote replicated pairs that are in the group.
Page 110: Removing A Replication Relationship

Removing a Replication Relationship Use the remove remoteReplication command to remove the link between a primary virtual disk and a secondary virtual disk. (Removing a replication relationship is similar to deleting a replication relationship.) Removing the link between a primary virtual disk and a secondary virtual disk does not affect any of the existing data on either virtual disk.
Page 111: Disabling The Remote Replication Premium Feature

Disabling the Remote Replication Premium Feature You disable the Remote Replication premium feature to prevent the new replication relationship from being created. When you disable the Remote Replication premium feature, the premium feature is in a Disabled/Active state. In this state, you can maintain and manage previously existing replication relationships;...
Page 112: Snapshot Virtual Disks

Snapshot Virtual Disks A snapshot is a point-in-time image of a virtual disk. Typically, it is created so that an application, such as a backup application, can access the snapshot virtual disk and read the data while the base virtual disk stays online and is accessible to hosts.

Page 117: Running A Consistency Check

The set virtualDisk command enables a media scan for the virtual disk. The following syntax is the general form of the command: set (allVirtualDisks | virtualDisk [virtualDiskName] | virtualDisks [virtualDiskName1 ... virtualDiskNamen] | virtualDisk <wwid>) mediaScanEnabled=(TRUE | FALSE) The set storageArray command defines how frequently a media scan is run on a storage array.
Page 118: Resetting A Raid Controller Module

Resetting a RAID Controller Module CAUTION: When you reset a RAID controller module, the RAID controller module is not available for I/O operations until the reset is complete. If a host is using virtual disks owned by the RAID controller module being reset, the I/O directed to the RAID controller module is rejected.
Page 119: Synchronizing Raid Controller Module Clocks

To determine which virtual disks have reservations, run the following command: show (allVirtualDisks | virtualDisk [virtualDiskName] | virtualDisks [virtualDiskName1 ... virtualDiskNameN]) reservations To clear persistent virtual disk reservations, run the following command: clear (allVirtualDisks | virtualDisk[virtualDiskName] | virtualDisks [virtualDiskName1" ...

Page 123: Troubleshooting And Diagnostics

Troubleshooting and Diagnostics If a storage array exhibits abnormal operation or failures, you can use the commands described in this section to determine the cause of the problems. Collecting Physical Disk Data To gather information about all the physical disks in a storage array, run the save allPhysicalDisks command.
Page 124: Recovery Operations

For best results, run all three tests at initial installation. Also, run the tests any time you make changes to the storage array or to components connected to the storage array (such as hubs, switches, and host adapters). A custom data pattern file called diagnosticsDataPattern.dpf is included on the Utility directory of the installation CD.
Page 125

Placing a RAID controller module online sets it to the Optimal state and makes it active and available for I/O operations. Placing a RAID controller module offline makes it unavailable for I/O operations and moves its disk groups to the other RAID controller module if failover protection is enabled. Taking a RAID controller module offline can seriously impact data integrity and storage array operation.
Page 126: Changing Raid Controller Module Ownership

Changing RAID Controller Module Ownership You can change which RAID controller module owns a virtual disk by using the set virtualDisk command. The following syntax is the general form of the command: set (allVirtualDisks | virtualDisk [virtualDiskName] | virtualDisks [virtualDiskName1 ...
Page 127: Reconstructing A Physical Disk

Reconstructing a Physical Disk If two or more physical disks in a disk group have failed, the virtual disk shows a status of Failed. All of the virtual disks in the disk group are no longer operating. To return the disk group to an Optimal status, you must replace the failed physical disks.
Page 128: Redistributing Virtual Disks

Redistributing Virtual Disks Redistributing virtual disks returns the virtual disks to their preferred RAID controller module owners. The preferred RAID controller module ownership of a virtual disk or disk group is the RAID controller module of an active- active pair that is designated to own the virtual disks. The preferred owner for a virtual disk is initially designated when the virtual disk is created.
Page 129: Script Commands

Page 313: A Sample Script Files

Sample Script Files This appendix provides sample scripts for configuring a storage array. These examples show how the script commands appear in a complete script file. You can copy these scripts and modify them to create a configuration unique to your storage array.
Page 314: Configuration Script Example 1

Configuration Script Example 1 This example creates a new virtual disk using the create virtualDisk command in the free space of a disk group. Show "Create RAID 5 Virtual Disk 7 on existing Disk Group 1"; //Create virtual disk on a disk group created by the create virtual disk command //Note: For disk groups that use all available capacity, the last virtual disk on the disk group...
Page 315

The first line of text is the show string command. This command displays text bounded by quotation marks (" ") on a monitor screen when the script file runs. In this example, the text Create RAID 5 Virtual Disk 7 on existing Disk Group 1 serves as a title describing the expected results of running this script file.
Page 316: Configuration Script Example 2

The set virtualDisk command parameters are shown on separate lines. You do not need to use separate lines for each parameter. You can enter more than one parameter with the set virtualDisk command by leaving a space between the parameters. By using separate lines, however, you can more clearly see what parameters you are setting and the values to which you are setting the parameters.
Page 317

The command in this example, like the create virtualDisk command in the previous example, creates a new virtual disk. The significant difference between these two examples is that this example shows how you can define specific physical disks to include in the virtual disk. To find out what physical disks are available in a storage array, run the show storageArray profile command.
