1 Introduction HP NetRAID-1M and 2M Adapters The HP NetRAID-1M (P3410A) and HP NetRAID-2M (P3411A with 64-MB cache memory, P3475A with 128-MB cache memory) 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 or two SCSI channels.
Chapter 1 Introduction HP NetRAID-1M The HP NetRAID-1M adapter supports one SCSI channel using either an internal or an external connection. The HP NetRAID-1M adapter supports: Fast/Wide SCSI (at data transfer rates of up to 20 MB/sec per channel) Ultra/Wide SCSI (at data transfer rates of up to 40 MB/sec per channel) Ultra2 SCSI (at data transfer rates of up to 80 MB/sec per channel) Ultra3 SCSI (at data transfer rates of up to 160 MB/sec per channel) The HP NetRAID-1M adapter supports a maximum of six or twelve devices per...
Chapter 1 Introduction HP NetRAID-2M The HP NetRAID-2M adapter has two channels with both internal and external connections. The HP NetRAID-2M adapter supports: Fast/Wide SCSI (at data transfer rates of up to 20 MB/sec per channel) Ultra/Wide SCSI (at data transfer rates of up to 40 MB/sec per channel) Ultra2 SCSI (at data transfer rates of up to 80 MB/sec per channel) Ultra3 SCSI (at data transfer rates of up to 160 MB/sec per channel) The HP NetRAID-2M adapter supports a maximum of six or twelve disk drives...
Chapter 1 Introduction Adapter Hardware and Battery-backed Cache IOP: The I/O processor (IOP) directs all functions of the adapter, including command processing, PCI and SCSI bus transfers, RAID processing, drive rebuilding, cache management, and error recovery. ® The IOP for the HP NetRAID-1M adapter is the Intel i960RM Intelligent I/O RISC processor running at 100 MHz.
Chapter 1 Introduction SCSI Termination and Firmware Termination: Active termination on the SCSI bus conforms to Alternative 2 of the SCSI-2 specifications. Termination enable/disable is automatic through cable detection. Firmware: The HP NetRAID-1M and 2M firmware handles all RAID and SCSI command processing and also supports the following functions: Disconnect/Reconnect feature optimizes SCSI Bus seek.
Chapter 1 Introduction Enhanced Array Spanning The HP NetRAID-1M and 2M adapters allow up to eight arrays to be spanned together as one logical drive, although all the disks in the logical drive must be connected to the same adapter. The maximum number of disks connected to one adapter depends on the number of channels (one or two) and whether you are using the internal or external SCSI connectors.
Chapter 1 Introduction Once disk modules are configured for HP NetRAID-1M or 2M adapters, they can be moved to different HP NetRAID-1M or 2M adapters, but not to earlier generation adapters. See Chapter 8, "Upgrading to an HP NetRAID-1M or HP NetRAID-2M Adapter,"...
Chapter 1 Introduction About This Guide This HP NetRAID-1M and 2M Installation and Configuration Guide will help you install your HP NetRAID-1M or HP NetRAID-2M adapter and plan the configuration. It guides you through power-up, launching the HP Netserver Navigator software, making the initial configuration of the adapter, and installing a NOS-specific configuration utility.

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- 1M and 2M adapters. For definitions of terms not introduced here, see the Glossary later in this guide. RAID Overview HP NetRAID-1M and 2M 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 of an HP NetRAID-1M or 2M adapter, or they can combine disk drives from both channels of an HP NetRAID-2M adapter. However, all the disk drives in an array must be connected to a single NetRAID adapter.
Chapter 2 RAID Overview HP NetRAID Adapter Channel 0 Channel 1 Spare Global Array A0 Array A1 Array A2 Hot Spare 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.
Chapter 2 RAID Overview Spanned arrays have logical drives that are spread across multiple arrays (as many as eight). This permits the physical drives in up to eight arrays to function as one large logical drive. Each spanned array must contain the same number of disks and all the disks in the logical drive must be connected to the same NetRAID adapter.
Chapter 2 RAID Overview Basic Arrays with Redundancy: RAID Levels 1 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 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. If you have five physical drives configured as one RAID 5 logical drive, data blocks are written as follows: Disk 1...
Chapter 2 RAID Overview Spanned Arrays: RAID Levels 10 and 50 With HP NetRAID-1M and 2M adapters, array spanning allows the capacity of up to eight basic arrays to be combined into a single storage space. A spanned array configuration must have the same number of disk drives in each basic array.
Chapter 2 RAID Overview RAID 10 Disadvantages Costs are high, because 50% of all disk space is allocated for redundancy. Capacity expansion is an offline operation only. RAID 10 Summary RAID 10 provides the best performance for most applications where redundancy and large logical drive size are required, and cost is not a factor.
Chapter 2 RAID Overview With the HP NetRAID-2M adapter, you can span up to eight RAID 5 arrays, although the total number of disks in the RAID 50 logical drive is limited by the number of disks that can be attached to the two SCSI channels.
Chapter 2 RAID Overview Table 2-2.

3 Installation and Configuration Overview To install and configure your HP NetRAID-1M or 2M adapter, you need to perform the following steps. Steps A through M are described in Chapters 4 through 7 of this guide. Step A. Plan Hardware (Chapter 4 and Step H.
Chapter 3 Installation and Configuration Overview Once you have installed and configured your new adapter, refer to Chapter 9, "Managing Servers Over the Network," and the HP NetRAID Series User Guide for information on managing your adapter from a remote location. Chapter 10, "Understanding HP NetRAID Utilities,"...
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 Sample Worksheet A Figure 4-1 shows a sample Configuration Worksheet A. (See Appendix C for a complete explanation of this example.) Adapter # 0 PCI Slot # 5 Rebuild Rate = 50 % Channel: CH 0 CH 1 Channel 0: Array # or Channel 1:...
Chapter 4 Planning Multiple Adapters The HP NetRAID 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 As explained in Chapter 1, "Introduction," for each channel, you have either one internal or one external connection. HP NetRAID-1M and 2M adapters support the following channels and connectors: The HP NetRAID-1M adapter provides an internal and external connector for Channel 0.
Chapter 4 Planning If a group contains three to five drives, and you checked Redundancy, the logical drive is assigned RAID level 5. If an array contains only one drive, the logical drive is assigned RAID level 0. (No redundancy is possible on a logical drive containing just one physical drive.) Automatic configuration does not create hot spares.
Chapter 4 Planning The physical drives in an array can be all on the same channel, or they can be on separate channels. You might plan to reserve one or more physical drives for use as a hot spare. See "Plan Hot Spares (Optional)" later in this chapter for more information.
Chapter 4 Planning Adapter 0 Channel: Physical Drives Array A0 Array A1 Figure 4-2. Two Logical Drives Where Each Array Uses a Different Channel Figure 4-3 shows the same configuration, except that Array A1 contains physical drives from both Channel 0 and Channel 1. Adapter 0 Channel: Physical...
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.

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 eight sequentially numbered arrays RAID level For each logical drive, you also need to define the logical drive size (capacity),...
Chapter 4 Planning Write Policy When the IOP writes to disk, the data is first written to the cache on the assumption that the IOP will read it again soon. The two Write policies are: Write-Through: In a write-through cache, data is written to disk at the same time it is cached.
Chapter 4 Planning Read Policy The three Read policies for HP NetRAID are: Read-Ahead: This is a memory caching feature that tells the adapter to read sequentially ahead of requested data and cache the additional data in memory, anticipating that the additional data will be requested. Read-Ahead supplies sequential data faster, but it is not as efficient when accessing random data.
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, "Planning." Step C.

7 Preparing for Online Capacity Expansion Step M. Prepare for Online Capacity Expansion The HP NetRAID Online Capacity Expansion feature allows you to add new storage capacity to drives controlled by an integrated HP NetRAID controller without rebooting the server. Online Capacity Expansion has these restrictions: You can use Online Capacity Expansion with any logical drive of RAID level 0 or 5.
Chapter 7 Preparing for Online Capacity Expansion Refer to one of the following sections in this chapter: See "Preparing for Online Capacity Expansion Under NetWare 4.2" if you are using Novell NetWare 4.2. See "Preparing for Online Capacity Expansion Under NetWare 5" if you are using Novell NetWare 5.x.
Chapter 7 Preparing for Online Capacity Expansion For example, assume you have one RAID-5 logical drive built from four physical hard disk drives of 4 GB each. The result is 12 GB of actual storage space. If you enable virtual sizing for this logical drive, then the operating system will see a logical drive of 144 GB.
Chapter 7 Preparing for Online Capacity Expansion NOTE SFT-3 and mirroring users: Novell’s operating system, which provides system level fault tolerance by mirroring two systems, is not compatible with the Online Capacity Expansion feature. SFT-3 mirrors disk storage on a partition basis rather than a volume basis.
Chapter 7 Preparing for Online Capacity Expansion for NetWare 4.2 Preparation Steps This section makes the following assumptions: You have already configured your HP NetRAID system as discussed in Chapter 5, "Installation and Configuration." You should have created only one logical drive per array. You have initialized your logical drives.
Chapter 7 Preparing for Online Capacity Expansion 4. Choose Objects from the Tools Management menu. 5. Choose Logical Drive from the Objects menu. 6. From the Logical Drives 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.
Chapter 7 Preparing for Online Capacity Expansion 6. Press the F10 key to save the partition. The free space becomes a NetWare partition. The Available Disk Options menu is displayed. III. Create the NetWare Volume How you create the NetWare volume depends on where you installed NetWare. For drives that do not contain the NetWare 4.2 operating system, see "Create Volumes on Drives that do not Contain NetWare 4.2."...
Chapter 7 Preparing for Online Capacity Expansion The new volume is now ready for use. Assume, for example, that the volume is called VOL1 and that its physical capacity is 12 GB. Its partition is 144 GB. Leave the remaining virtual storage space (144 GB minus 12 GB) as unused.
Chapter 7 Preparing for Online Capacity Expansion Preparing for Online Capacity Expansion under NetWare 5.x About Capacity Expansion under NetWare 5.x 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. The Online Capacity Expansion feature allows you to expand an existing logical drive without shutting down the server.
Chapter 7 Preparing for Online Capacity Expansion In most installations, the operating system is installed on a SCSI drive connected outside of the HP NetRAID system. However, NetWare 5.x can reside on a disk array in the HP NetRAID system to achieve redundancy. for NetWare 5.x Preparation Steps This section makes the following assumptions:...
Chapter 7 Preparing for Online Capacity Expansion 1. Restart the host HP Netserver, and watch for the message: Option: Experienced users may press <Ctrl> <M> for HP NetRAID Express Tools now. Firmware Initializing 2. When the message is displayed, press <Ctrl> <M>. When the system stops scanning, HP NetRAID Express Tools starts and displays the Tools Management menu.
Chapter 7 Preparing for Online Capacity Expansion Preparing for Online Capacity Expansion under Windows NT About Capacity Expansion under Windows NT Normally, adding capacity requires shutting down the server to reconfigure or restore an existing volume or to add the new storage space as a new volume. Using the Online Capacity Expansion feature allows you to expand an existing logical drive without shutting down the server.
Chapter 7 Preparing for Online Capacity Expansion sure to use no more than the actual available physical capacity. Capacity of the logical drive can be checked with the HP NetRAID Assistant under Windows The Online Capacity Expansion feature cannot be used if a logical drive spans multiple arrays.
Chapter 7 Preparing for Online Capacity Expansion I. Enable Virtual Sizing NOTE Clearing a previous configuration does not reset the virtual sizing setting for a logical drive. Use the Reset to Factory Defaults option in HP NetRAID Express Tools to disable virtual sizing for all logical drives, or manually change the setting as described below.
Chapter 7 Preparing for Online Capacity Expansion 11. If there is more than one HP NetRAID-1M or 2M adapter installed (including any integrated HP NetRAID controller), press Esc to return to the Objects menu. Enable virtual sizing on the logical drives of all adapters as necessary.
Chapter 7 Preparing for Online Capacity Expansion The formatted drive is now ready for use. Assume for this example that the drive is now E: and was partitioned as a primary partition. The remaining virtual storage space (500 GB minus 12 GB) must be left unpartitioned. You can write data up to 12 GB on the drive.
Chapter 7 Preparing for Online Capacity Expansion This section describes preparation for online capacity expansion for logical drives operating in Basic Disk Mode under Windows 2000. (Capacity cannot be expanded online for logical drives operating in Dynamic Disk Mode.) Preparation for capacity expansion under Windows 2000 operating in Basic Disk Mode is simply to leave virtual sizing disabled (the factory default), or to disable it if it has been enabled.
Chapter 7 Preparing for Online Capacity Expansion The only other requirement to prepare for online capacity expansion of your logical drive is that virtual sizing is disabled. This is the factory default setting. If Virtual Sizing is Disabled (the factory default setting), no other preparation is necessary.
Chapter 7 Preparing for Online Capacity Expansion 7. From the Logical Drive menu for the drive you want to prepare, choose Properties. 8. Choose Virtual Sizing. 9. On the Virtual Size menu, choose Disable, and confirm your choice. 10. Press Esc twice to return to the Logical Drive menu. If you need to enable virtual sizing on another logical drive, choose the logical drive and repeat steps 6 through 10.
8 Upgrading to an HP NetRAID-1M or HP NetRAID-2M Adapter This chapter explains how to replace an existing HP NetRAID adapter with an HP NetRAID-1M or HP NetRAID-2M adapter. When you replace one adapter with another, you must consider data compatibility. Data created using one HP NetRAID adapter is not necessarily compatible with any other HP NetRAID adapter.
Chapter 8 Upgrading to an HP NetRAID-1M or HP NetRAID-2M Adapter Back Up Your Data Back up all data on the drives controlled by the adapter that will be removed. Load the Appropriate HP NetRAID Driver To load the required HP NetRAID drivers, you will follow these steps as described in Chapter 6, "HP NetRAID Software,"...
Chapter 8 Upgrading to an HP NetRAID-1M or HP NetRAID-2M Adapter To remove any HP NetRAID adapter and replace it with a new adapter, do the following: 1. Turn off the system, unplug the power cord(s) from the system, open the HP Netserver panel or remove the HP Netserver cover, and disconnect the SCSI cables from the existing HP NetRAID adapter.

Appendix C Worksheets Figures C-3 and C-4 are samples of Worksheets A and B for an HP NetRAID adapter with ten physical drives, three arrays, and three logical drives. It is adapter #0 in PCI Slot #5 in the HP Netserver, and it has a 50% rebuild rate. Physical Arrays and Hot Spares Array 0 on Channel 0 contains three 9-GB physical drives (SCSI ID # 1, 2, 3).
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 adapter can group disk modules on one or more of its SCSI channels into an array. A hot spare disk module does not participate in an array.
Glossary Under Windows NT or NetWare 4.2, enable virtual sizing to prepare for online capacity expansion. The controller creates virtual space when the "virtual sizing" option is enabled in the HP NetRAID Express Tools utility. A volume can then be expanded into the virtual space by adding a physical disk through reconstruction.
Glossary pass a Consistency Check. Arrays work without initializing, but they may fail a Consistency Check because parity fields may not have been generated. IOP: The IOP (I/O Processor) for the integrated HP NetRAID controller directs all functions of the controller, including command processing, PCI and SCSI bus transfers, RAID processing, drive rebuilding, cache management, and error recovery.
Glossary from two or more parent data sets. The redundancy data can be used to reconstruct one of the parent data sets; however, parity data do not fully duplicate the parent data sets. In RAID, this method is applied to entire drives or stripes across all disk drives in an array.
Glossary RAID 10 results when data is striped across multiple RAID 1 logical drives. RAID 50 results when data is striped across multiple RAID 5 logical drives. Read Policy: The three Read policies for HP NetRAID are: Read-Ahead: This is a memory caching ability that tells the adapter to read sequentially ahead of requested data and cache the further data in memory, anticipating that the further data will be requested.
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.
