  • Page 13: 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 14: 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 15: Usage Notes

    The following syntax is the general form of a CLI command: SMcli storageArray parameters script-commands; SMcli Invokes the command line interface storageArray Host name or IP address of the storage array parameters CLI parameters that define the environment and purpose for the command script-commands One or more script commands or the name of a script file containing script commands...

    Command Line Parameters Table 1-2. Command Line Parameters Parameter Definition host-name-or-IP-address Specify either the host name or the Internet Protocol (IP) address of an in-band managed storage array (IPv4 or iPv6) or an out-of-band managed storage array (IPv4 only). • If you manage a storage array by using a host connected directly to the storage array (in-band storage management), you must use the -n parameter if more than one storage array is connected to the host.
  • Page 19 Table 1-2. Command Line Parameters (continued) Parameter Definition Use to indicate that you are entering one or more script commands to run on the specified storage array. Terminate each command by using a semicolon (;). You cannot place more than one -c parameter on the same command line.

Command Line Parameters (continued) Parameter Definition Use to specify an ASCII file that contains email sender contact information to include in all email alert notifications. The CLI assumes the ASCII file is text only, without delimiters or any expected format. A typical file contains the following information: •...
  • Page 21 Table 1-2. Command Line Parameters (continued) Parameter Definition Use to specify the name of the storage array on which to run the script commands. This name is optional when you use host-name-or-IP-address; however, if you are using the in-band method for managing the storage array, you must use the -n parameter if more than one storage array is connected to the host at the specified address.

  • Page 24: 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.
  • Page 25: 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 26 Table 1-3. Exit Status (continued) 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: 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.

    The following commands also return information about a storage array: • show storageArray autoConfigure ("Show Storage Array Autoconfigure" on page 204) • show controller NVSRAM ("Show RAID Controller Module NVSRAM" on page 201) • show storageArray unreadableSectors ("Show Storage Array Unreadable Sectors"...

    You can choose to save the entire configuration or specific configuration features. The command for setting this parameter value looks like the following example: 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.
  • Page 49 NOTE: The capacity, owner, segmentSize, and enclosureLossProtect parameters are optional. You can use one or all of the optional parameters as needed to help define your configuration. You do not, however, need to use any optional parameters. 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.
  • Page 50 The command in this example automatically creates a new disk group and a virtual disk with the name Engineering_1. The disk group will have a RAID level of 5 (RAID 5). The command uses three physical disks to construct the disk group.
  • Page 51 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 52 The userLabel, capacity, owner, and segmentSize parameters are the same as in the previous versions of the create virtualDisk 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.
  • Page 53: Using The Auto Configure Command

    Using the Auto Configure Command The autoConfigure storageArray command creates the disk groups on a storage array, the virtual disks in the disk groups, and the hot spares for the storage array. When you use the autoConfigure storageArray command, define the following parameters: •...
  • Page 54 NOTE: All parameters are optional. You can use one or all of the parameters as needed to define your configuration. 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.
  • Page 55: 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 56: 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 47). If you have problems with your modifications, you can use the information in the file to restore your previous configuration.

  • Page 58: 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.

    • 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 60 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.
