1 Introduction HP NetRAID Series Adapters The HP NetRAID (HP D4943A), HP NetRAID-1 (HP D4992A), and HP NetRAID-3Si (D5955A) adapters provide an interface between the host system and a disk array storage system. The adapters use the PCI (Peripheral Component Interconnect) standard to control data transfers on one to three SCSI channels.
Chapter 1 Introduction Features of the HP NetRAID Series Adapters The HP NetRAID, HP NetRAID-1 and HP NetRAID-3Si adapters are high- performance, intelligent PCI-to-SCSI host adapters with RAID control capabilities. The HP NetRAID Series adapters have SCSI channels with both internal and external connections.
Chapter 1 Introduction HP NetRAID-3Si External SCSI Cables Channel External SCSI Cable D6020A D3637C or D6020A D6020A (1) External connections to both Channel 0 and Channel 2 at the same time require two D6020A SCSI Cables. The connectors for Channels 0 and 2 are very close together, and these cables have offset connectors that allow them to fit side-by-side.
Chapter 1 Introduction HP NetRAID Devices Per Channel Channel Internal Connection External Connection* 6 or 8 6 or 8 * External storage with the HP Storage System/6 supports a maximum of six Fast/Wide SCSI devices, while external storage with the HP Rack Storage/8 supports a maximum of eight Fast/Wide or Ultra/Wide SCSI devices.
Chapter 1 Introduction HP NetRAID-1 Devices Per Channel Channel Internal Connection External Connection * 6 or 8 * External storage with the HP Storage System/6 supports a maximum of six Fast/Wide SCSI devices, while external storage with the HP Rack Storage/8 supports a maximum of eight Fast/Wide or Ultra/Wide SCSI devices.
Chapter 1 Introduction For the HP NetRAID-1 adapter, cache memory resides in a 4 MB non- battery-backed 60-ns FPM DRAM SIMM and cannot be upgraded. NOTE The HP NetRAID-1 adapter does not have a Battery Backup Unit. The HP NetRAID Series adapters support Direct and Cached I/O and Write Through or Write Back caching, which can be selected for each logical drive.
Chapter 1 Introduction New Features of HP NetRAID Series Adapters New features of HP NetRAID Series adapters include: Enhanced Array Spanning Enhanced Configuration Replication Support for Clustering O Support (HP NetRAID-3Si adapters only) Enhanced Array Spanning The HP NetRAID Series adapters allow up to four arrays to be spanned together as one logical drive, rather than the two-array maximum supported previously.
Chapter 1 Introduction O Support (HP NetRAID-3Si Adapters Only) HP NetRAID-3Si adapters support I O (Intelligent Input/Output) with some operating systems. For a complete list of operating systems for which HP NetRAID I O drivers are available, see the HP web site at www.hp.com/go/netserver Physical Disk Roaming and Data Migration HP NetRAID Series adapters allow physical disk roaming, in which the adapter...
Chapter 1 Introduction Changing Capacity and RAID Levels HP NetRAID Series adapters can expand capacity and change RAID levels of logical drives without powering down the server. Online Capacity Expansion: You can add a physical drive to a RAID 0, 3, or 5 logical drive.
Chapter 1 Introduction The HP NetRAID Series Installation and Configuration Guide is intended to be used in conjunction with your HP NetServer documentation. Refer to your system documentation for details such as cable product numbers and I/O slot boot order. If you are setting up your HP NetServer for the first time, begin with the HP NetServer Installation Road Map that came with your system.
Chapter 1 Introduction CAUTION All HP NetRAID adapter cards are sensitive to static electricity and can easily be damaged by improper handling. Using a grounding strap is recommended. Read the following information carefully before you handle the accessory: Leave the adapter card in the antistatic bag until you are ready to install it.
2 RAID Overview This chapter summarizes concepts and terminology used to describe RAID systems. It describes the different RAID levels available with the HP NetRAID Series adapters. For definitions of terms not introduced here, see the Glossary. RAID Overview HP NetRAID Series adapters let you link multiple hard disk drives together and write data across them as if they were one large drive.
Chapter 2 RAID Overview Arrays can combine disk drives that are all on one channel, or they can combine disk drives from two or three different channels. Hot Spare A hot spare is a powered-on, stand-by disk drive that is ready for use should another disk drive fail.
Chapter 2 RAID Overview Figure 2-3. Sample Configuration with Three Arrays and Three Logical Drives Understanding RAID Levels During installation, you configure your logical drives by running a disk array configuration utility. Each of the logical drives you define must have an assigned RAID level.
Chapter 2 RAID Overview Arrays with No Redundancy: RAID Level 0 RAID 0: Striping In RAID 0 configurations, data is distributed among hard disks in the array via an algorithm called striping. Data written to a logical drive is divided into pieces called blocks.
Chapter 2 RAID Overview Non-spanned Arrays with Redundancy: RAID Levels 1, 3, and 5 RAID 1: Mirroring In RAID 1 configurations, data on one disk is completely duplicated on another disk. This is called mirroring. RAID 1 must be configured on a two-disk array. (The array cannot contain more than two disk drives.) With this algorithm, if either of the two disks fail, data is available from the duplicate disk.
Chapter 2 RAID Overview RAID 3: Striping with Dedicated Parity In RAID 3 configurations, each data stripe generates one parity block to provide redundancy and data protection. The parity block is encoded information that can be used to reconstruct the data on that stripe if one of the disks fails. RAID 3 configurations dedicate one disk in the array to store all parity blocks.
Chapter 2 RAID Overview RAID 5: Striping with Distributed Parity RAID 5 is the most common configuration because it provides good overall performance and data protection with a minimum loss of storage capacity. RAID 5 distributes the parity blocks equally among all disk drives to achieve better overall performance than if a dedicated parity disk is used (RAID 3).
Chapter 2 RAID Overview Spanned Arrays: RAID Levels 10, 30, and 50 With HP NetRAID and NetRAID-3Si adapters, array spanning allows the capacity of two, three, or four arrays to be combined into a single storage space. A spanned array configuration must have the same number of disk drives in each array: each array can have two disks, three disks, four disks, and so on.
Chapter 2 RAID Overview RAID 30: Spanning with Dedicated Parity Drives In RAID 30 configurations, parity blocks provide redundancy to a logical drive that spans two, three, or four arrays. (RAID 30 is a RAID 3 configuration with array spanning.) If your RAID 30 logical drive has two arrays with four physical drives each, data blocks are written as follows: Array 1 Array 2...
Chapter 2 RAID Overview RAID 50: Spanning with Distributed Parity In RAID 50 configurations, parity blocks are distributed throughout the logical drive that spans two, three, or four arrays. (RAID 50 is a RAID 5 configuration with array spanning.) If your RAID 50 logical drive has two arrays with four physical drives each, data blocks are written as follows: Array 1 Array 2...

3 Installation and Configuration Overview To install and configure your HP NetRAID Series adapter, you need to perform the following steps. Steps A through N are described in Chapters 4 through 7 of this guide. Step A. Plan Hardware (Chapter 4 and Step H.
4 Planning Overview Before attempting to install and configure your disk array subsystem, you should invest some time in planning the configuration that best suits your computing environment. The options you choose depend on factors such as the host operating system used and your requirements for data protection, performance, and capacity.
Chapter 4 Planning Performance requirements Storage capacity requirements Whether you want hot spare capability Sample Worksheet A Figure 4-1 shows a sample Configuration Worksheet A. (See Appendix C for a complete explanation of this example.) Figure 4-1. Sample Worksheet A for HP NetRAID Series Adapter...
Chapter 4 Planning Multiple Adapters The disk array drivers and firmware will support up to six adapters, but your particular model of HP NetServer may have fewer PCI slots available. Be sure to check your system's PCI I/O slot availability and any slot restrictions before purchasing another adapter.
Chapter 4 Planning Log the adapter's PCI slot on Worksheet A. Channels In this section you determine which physical devices will connect to each SCSI channel of the adapter. Record the SCSI ID number and physical capacity of each disk drive in the correct channel on Worksheet A. No two devices on a single channel can have the same SCSI ID.
Chapter 4 Planning Step B. Plan Arrays and Logical Drives There are two ways to set up arrays and logical drives. Automatic configuration is explained for those users who do not want to customize their arrays and logical drives. Custom configurations permit you to create exactly the configuration that best suits your needs.
Chapter 4 Planning Custom Configuration To plan a custom configuration, you will do the following: Plan your arrays Plan hot spares Decide the rebuild rate Plan logical drives Plan Your Arrays In this section you specify which physical drives are assigned to which arrays. For each physical disk drive that is assigned to an array, log its array number in Worksheet A.
Chapter 4 Planning Consider what RAID levels you will need. Different RAID levels require different minimum numbers of physical drives. For example, RAID 1 requires exactly two physical drives, RAID levels 3 and 5 require at least three physical drives, and arrays with only one physical drive must be assigned RAID 0.
Chapter 4 Planning Figure 4-2. Three Logical Drives Where Each Array Uses a Different Channel Figure 4-3 shows the same configuration, except Array A1 contains physical drives from both Channel 0 and Channel 1, and Array 2 contains physical drives on Channels 1 and 2.
Chapter 4 Planning Plan Hot Spares (Optional) On Worksheet A for each adapter, log any hot spare disk modules and indicate whether each is global or dedicated to a particular array. A hot spare is a powered-on, stand-by disk that is ready for use should another disk fail.
Chapter 4 Planning Plan Logical Drives Logical drives are virtual drives configured within an array or across arrays. Logical drives can take three forms: A logical drive can use all of the storage capacity of one array. A logical drive can use less than the available storage capacity of one array.
Chapter 4 Planning Although each drive in an array must have the same capacity, one logical drive can span two or more arrays with different capacities. For example, one array might contain three drives of 4 MB each, and the second array might contain three drives of 12 MB each.
Chapter 4 Planning Figure 4-4. Sample Worksheet B Logical Drives, RAID Levels, and Array Spanning On Worksheet B, logical drives are numbered LD0 through LD7. For each logical drive you plan to create, record the following information: Array number to which the logical drive is assigned Whether the logical drive spans up to four sequentially-numbered arrays RAID level For each logical drive, you also need to define the logical drive size (capacity),...
Chapter 4 Planning Logical Drive Size You can calculate the usable capacity to assign to each logical drive, or you can let the HP NetRAID Assistant Wizard specify it during configuration. If you calculate logical drive capacity, record it in Worksheet B. If you want a logical drive to occupy less space than is available on one array, you must enter the logical drive size.
Chapter 4 Planning Write Back: In a write-back cache, data is written to disk only when it is forced out of the cache. Write-back is efficient, because an entry may be written many times in the cache without a disk access. Write Back can be used if an Uninterruptible Power Supply maintains the data in cache memory in the event of a power failure.
5 Installation and Configuration Overview This chapter covers Steps C, D, E, F, G, and H of the installation procedure. You should already have completed Step A, "Plan Your Hardware," and Step B, "Plan Arrays and Logical Drives" in Chapter 4. Step C.

Failure to follow these procedures may result in breaking the power management board. 5. To remove an existing adapter, disconnect its SCSI cables first. Install the Adapter CAUTION Do not allow the adapter to contact any part of the...
Chapter 5 Installation and Configuration Step E. Install Cables and Set SCSI ID Switches In this step you connect the adapter's SCSI channels to the physical drives listed in Worksheet A and set their SCSI ID switches. Connect Cables and Set SCSI ID Switches Install the cables to create the hardware setup you planned in Worksheet A.
Chapter 5 Installation and Configuration Note the cable requirements for the HP NetRAID-3Si: The external connectors for Channels 0 and 2 on the HP NetRAID-3Si are very close together and require D6020A cables with offset connectors. Some nonstandard cable configurations and switch settings are listed in the HP NetServer user guides.
Chapter 5 Installation and Configuration CAUTION Handle disk modules carefully. They are more susceptible to shock, vibration, and electrostatic discharge when they are not in the cabinet. When removing a module while the system is powered on, disengage the module and wait for it to stop spinning before removing it from its hot swap shelf.
Chapter 5 Installation and Configuration Select Configure Disk Array If HP Navigator asks you to set the date, time, and so on, do so. The HP Navigator Main Menu then appears. 1. When the HP Navigator Main Menu is displayed, choose NetServer Utilities.
Chapter 5 Installation and Configuration The HP NetRAID Assistant, shown in Figure 5-4, is an object-oriented graphical user interface (GUI) with conventions similar to those in Microsoft Windows. Click on an object with the left mouse button to select or deselect it. Chapter 10 lists all the menus that are available by clicking on menu bar items.
Chapter 5 Installation and Configuration Physical Devices box: The Physical Devices box contains either one channel (for an HP NetRAID-1 adapter), or three channel boxes (for an HP NetRAID or HP NetRAID-3Si adapter), which show the physical drives on the SCSI channels of the current adapter. The number in parentheses to the right of each physical drive icon is its SCSI ID (Target) on the channel.

6 HP NetRAID Series Software Overview In this chapter you will complete the next five steps in the installation: In Step I, you choose whether you want to use I O or non-I HP NetRAID drivers In Step J, you use the HP NetServer Navigator CD-ROM to prepare the diskettes needed to install the NOS, HP NetRAID drivers, and the HP NetRAID NOS-specific utilities In Step K, you install the network operating system (NOS) if necessary...
Chapter 6 HP NetRAID Series Software Information about I O drivers are not included in this guide. For complete information on which operating systems are supported with I O and instructions on installing I O drivers, see the HP web site at www.hp.com/go/netserver Step J.
Chapter 6 HP NetRAID Series Software Create Drivers Diskette and Instructions You must use the HP NetServer Navigator CD-ROM to create the diskette containing the drivers for your NOS and the instructions for installing them. 1. Turn on the HP NetServer and monitor, and insert the HP NetServer Navigator CD-ROM into the drive.
Chapter 6 HP NetRAID Series Software NOTE You can skip this step if your NOS is IBM OS/2, SCO UNIX, SCO UnixWare, or Banyan VINES. For these network operating systems, the HP NetRAID configuration utility was copied to the drivers diskette that you have already created. To create the diskette needed to install the NOS-specific utility for Windows NT or Novell NetWare: 1.
Chapter 6 HP NetRAID Series Software Step K. Install NOS and HP NetRAID Drivers Install Network Operating System (if necessary) If the NOS is not already installed on the HP NetServer, install it according to the instructions you printed in Step J after you created the HP NetRAID drivers diskette.
Chapter 6 HP NetRAID Series Software Step L. Install NOS-specific Configuration Utility NOTE Skip this step if your NOS is SCO UNIX, SCO UnixWare, or Banyan VINES. For these network operating systems, the HP NetRAID Config utility was installed automatically with the drivers.
Chapter 6 HP NetRAID Series Software IBM OS/2 Warp Server SMP 4.0 1. Open a command prompt window. 2. Change to the drive where the utility is to be installed. 3. Type cd\ and press the Enter key. 4. Type md NetRAID and press the Enter key. 5.
Chapter 6 HP NetRAID Series Software SCO ODT 3.0, MPX 3.0, Open Server 5.0.x, and UnixWare 2.1.x No instructions are necessary. The HP NetRAID Config utility was installed automatically when you installed the HP NetRAID driver. Banyan VINES 6.x and 7.x No instructions are necessary.
Chapter 6 HP NetRAID Series Software Set the SCSI Transfer Rate if you are using Ultra or Ultra2 SCSI devices. Change SCSI terminations. Disable the adapter BIOS to prevent booting from the adapter. Enable the Power Fail Safeguard feature. To start HP NetRAID Express Tools: 1.
Chapter 6 HP NetRAID Series Software 4. Select the channel on which the SCSI Transfer Rate or the termination is to be changed. 5. To change the SCSI Transfer Rate: Choose SCSI Transfer Rate from the SCSI Channel menu. A submenu appears.
Chapter 6 HP NetRAID Series Software Enable Power Fail Safeguard The Power Fail Safeguard feature lets you protect a disk array during the reconstruction process should a power failure occur. When you use this feature, a copy of the data currently being reorganized always remains on disk, so there is no risk of losing data.
Chapter 6 HP NetRAID Series Software 5. Save the configuration; the system will reboot. For backup purposes, we recommend that you save the EISA configuration on a diskette. Refer to the host system documentation for instructions on how to do this.
7 Preparing for Online Capacity Expansion Step N. Prepare for Online Capacity Expansion The HP NetRAID Online Capacity Expansion feature allows you to add new storage capacity to drives controlled by an HP NetRAID Series adapter without rebooting the server. Online Capacity Expansion has these restrictions: Online Capacity Expansion has a maximum capacity of 82 GB.
Chapter 7 Preparing for Online Capacity Expansion This chapter is divided into two sections: See "Capacity Expansion Under Novell NetWare" if you are using Novell NetWare. See "Capacity Expansion Under Windows NT" if you are using Microsoft Windows NT. Online Capacity Expansion Under Novell NetWare Theory of Operation Normally, to add capacity you must shut down the server to reconfigure and then restore data, or you must add the new storage space as a new volume.
Chapter 7 Preparing for Online Capacity Expansion Although undesirable, NetWare allows you to create volumes into the virtual space. This is because during volume creation, NetWare only looks at the beginning of the volume and if there is real storage space there, the volume will be created.
Chapter 7 Preparing for Online Capacity Expansion Preparing for Online Capacity Expansion This section describes how to enable Virtual Sizing and set up your partitions to permit easy capacity expansion. For NetWare installations, plan ahead and consider your storage use. Since NetWare permits only one NetWare partition per logical drive, make the NetWare partition the size of the virtual logical drive in advance so that you can expand that volume.
Chapter 7 Preparing for Online Capacity Expansion NOTE It is important to initialize your logical drives. If the drives have been previously configured under an operating system, there can sometimes be residual partition/format information which subsequently causes misrepresentation of logical drives under NetWare's Install module.
Chapter 7 Preparing for Online Capacity Expansion 11. If you have multiple adapters, press ESC to return to the Objects menu. Enable Virtual Sizing on the logical drives of all adapters as necessary. 12. To exit, press ESC until you see the Exit? box, then choose Yes. NOTE Clearing a previous configuration does not reset the Virtual Sizing setting for a logical drive.
Chapter 7 Preparing for Online Capacity Expansion for use. Be sure not to exceed the actual physical capacity when creating the 12-GB volume and include other uses such as a Hot Fix area. The new volume is now ready for use. Assume for this example, the volume is called VOL1.
Chapter 7 Preparing for Online Capacity Expansion NOTE The additional capacity will have a different drive letter than the original logical drive. If the expanded capacity and the original capacity must share the same drive letter, you cannot expand capacity online and you must reboot NT. For more information about drive letters, see "Capacity Expansion"...
Chapter 7 Preparing for Online Capacity Expansion Setting Up Your Array for Capacity Expansion This section makes the following assumptions: You have already installed your drives and configured your adapter as discussed in Chapter 4. You should have created only one logical drive per array.
Chapter 7 Preparing for Online Capacity Expansion 6. From the Logical Drive menu, choose the logical drive you want to prepare for expansion. 7. From the Logical Drive menu for the drive you want to prepare, choose Properties. 8. Choose Virtual Sizing. 9.
Chapter 7 Preparing for Online Capacity Expansion Partition and Format Drives that do not Contain Windows NT Follow these instructions for drives that do not contain Windows NT. 1. Create a partition equal to (or less than) the real storage capacity. In our ongoing example, you would create a 12 GB partition.
8 Upgrading to an HP NetRAID-3Si Adapter This chapter explains how to replace an existing adapter with an HP NetRAID- 3Si adapter. When you replace one adapter with another, you do not need to worry about data compatibility. Data created using any HP NetRAID Series adapter is compatible with any other HP NetRAID Series adapter.
Chapter 8 Upgrading to an HP NetRAID-3Si Adapter 2. Use the HP NetServer Navigator CD-ROM to prepare the diskettes you need to install the non-I O drivers and the HP NetRAID configuration utility specific to your NOS. See Step J for complete instructions. 3.
Chapter 8 Upgrading to an HP NetRAID-3Si Adapter 2. Install the new HP NetRAID-3Si adapter, as described in Step D of Chapter 5. Be sure to plug in the Battery Backup Unit first. 3. Connect all SCSI cables to the HP NetRAID-3Si, as described in Step E of Chapter 5.
Chapter 8 Upgrading to an HP NetRAID-3Si Adapter 12. Choose Yes to save the configuration. The HP NetRAID Express Tools utility now updates the configuration stored in NVRAM on the newly installed adapter. 13. Press ESC repeatedly to exit HP NetRAID Express Tools. 14.

Examples of operations that you can perform in View Only mode are displaying the properties of physical and logical drives and viewing the adapter configuration. NOTE You cannot enter Full Access mode on a server if one of its adapters is already being managed by HP NetRAID Assistant in Full Access mode, or by another HP NetRAID utility.
10 Understanding HP NetRAID Utilities After you have installed the adapter and configured your system, there are three utilities that help you manage HP NetRAID systems. All adapters (HP NetRAID, NetRAID-1, and NetRAID-3Si) use the same utilities. However, all utilities are not available to all network operating systems.

Chapter 10 Understanding HP NetRAID Utilities HP NetRAID Config HP NetRAID Config performs the same functions as HP NetRAID Assistant, but it runs under Novell NetWare, SCO UNIX, SCO UnixWare, IBM OS/2, and Banyan VINES. HP NetRAID Config allows you to reconfigure and manage your RAID system and monitor its status.

11 Troubleshooting Power-up (Boot) Error Messages Adapter BIOS Disabled. No Logical Drives Handled by BIOS Problem: The adapter BIOS is disabled. (This is not a problem if the BIOS is intentionally disabled to prevent booting from the adapter.) Suggested solution: Enable the BIOS by using HP NetRAID Express Tools, as described in "Run Configuration Utilities"...
Chapter 11 Troubleshooting Suggested solution: 1. Press any key to enter HP NetRAID Express Tools. 2. Run the View/Add Configuration option of HP NetRAID Express Tools, as described in the HP NetRAID Series User Guide in Information Assistant. 3. Use View/Add Configuration to examine both configurations, the one on the drives and the one in NVRAM.
Chapter 11 Troubleshooting x Logical Drives Degraded Problem: x number of logical drives signed on in the degraded (critical) state. Suggested solution: 1. Use a utility, such as HP NetRAID Assistant or HP NetRAID Config, to determine which physical drive(s) is not responding and thereby makes the logical drives degraded.
Chapter 11 Troubleshooting Following SCSI ID's are not Responding Channel-x:a.b.c Problem: On the channel listed (x), the physical drives with the SCSI IDs listed (a, b, c, and so on) are not responding. Suggested solution: Verify that the physical drives are connected and powered Other BIOS Error Messages Warning: Battery voltage Low Problem: The voltage of the battery backing the cache memory is low.
Chapter 11 Troubleshooting Following SCSI ID’s have the same data <v.z> Channel-x:a.b.c Problem: The physical disk roaming feature found the same data on two or more physical drives on channel (x) with the listed SCSI IDs (a, b, c, and so on). The adapter cannot determine which drive with duplicate information to use.
Chapter 11 Troubleshooting Hard Drive Fails Often Problem: One of the hard drives in the array fails often. Suggested solutions: Check the drive error counts using HP NetRAID Assistant Physical Drive Properties. Be aware that the drive error counter clears if the drive is moved or powered off while the adapter remains powered on.
Chapter 11 Troubleshooting Cannot Flash or Update the EEPROM Problem: Cannot flash or update the EEPROM. Suggested solution: Make sure that Pins 2-3 of J5 are shorted on the adapter card. If J5 is OK, you may need a new EEPROM. BIOS Banner Not Displayed Problem: The BIOS and firmware banner does not appear.
Chapter 11 Troubleshooting Common Problems Without NetRAID Assistant, the client(s) and server(s) connect normally, but the NetRAID Assistant cannot connect to any servers For NetRAID Assistant to connect to a server, it must resolve the server via TCP/IP. Ping the server by name from the client or server that will run HP NetRAID Assistant.

Glossary Disk Array Terms and Technologies Array: An array of disk modules combines the storage space on the disk modules into a single segment of contiguous storage space. The HP NetRAID Series adapters can group disk modules on one or more of its SCSI channels into an array.
Glossary logical drive in the array. You cannot use online capacity expansion on logical drives that span arrays (RAID levels 10, 30, or 50). Channel: An electrical path for the transfer of data and control information between a disk and a disk adapter. Format: The process of writing zeros to all data fields in a physical drive (hard drive) and to map out unreadable or bad sectors.
Glossary pass a Consistency Check. Arrays work without initializing, but they may fail a Consistency Check because parity fields may not have been generated. Logical Drive: A virtual drive within an array, which may consist of more than one physical disk. Logical drives divide up the contiguous storage space of an array of disk modules or a spanned group of arrays of disks.
Glossary the system. If a single disk fails, it can be rebuilt from the parity of the respective data on the remaining disks. Physical Disk Roaming: The ability of an adapter to keep track of a hot swap disk module that has been moved to a different slot in the hot swap cages. Both slots must be controlled by the same adapter.
Glossary RAID 5 has parity redundancy distributed over all the disks in the array. It requires three or more physical drives in an array. RAID levels 10, 30, and 50 result when logical drives span arrays. Table 2-2 in Chapter 2 describes RAID levels for logical drives that span arrays. RAID 10 results when a RAID 1 logical drive spans arrays.
Glossary SCSI Disk Status: A SCSI disk module (physical drive) can be in one of five states: Ready: a powered-on and operational disk that has not been configured. Online: a powered-on and operational disk that has been configured. Hot Spare: a powered-on, stand-by disk ready for use should a disk fail. Not Responding: the disk is not present, not powered-on, or has failed.
Glossary Write Policy: When the processor writes to main memory, the data is first written to the cache on the assumption that the processor will probably read it again soon. The two Write policies for HP NetRAID are: Write Back: In a write-back cache, data is written to main memory only when it is forced out of the cache.
