StorageWorks RAID Array 200 Subsystem Family RAID Overview RAID (redundant array of independent disks) is a modular, integrated, end-user solution that provides three main benefits: • Improved data availability • Improved I/O performance • Increased scaleability A RAID array is a set of multiple disk drives and a specialized array controller that manages how data is distributed across disk drives. Data for a given file is divided into segments, which can be written across multiple drives.
Chapter 1 Raid 0 + 1 RAID 0 + 1 is achieved in a multidrive RAID set by the combination of striping mirrored sets. RAID 0 + 1 provides data redundancy and is beneficial for any critical high-availability application. If a drive fails in a RAID 0 + 1 array, you can continue to use the array normally since data from its mirrored drive is automatically retrieved. Raid 5 RAID 5 combines striping (writing data across the set of drives) and storing parity across all drives.
StorageWorks RAID Array 200 Subsystem Family Logical RAID Drive States The logical RAID drive or grouping of drives can be in different states. There are four possible states as shown in Figure 1-1 and described in Table 1-1. Figure 1-1. Logical RAID Drive State Diagram Table 1-1. Logical RAID Drive States 1-6 States Description Optimal The array is operating at an optimal level. This is the condition during normal operation. Degraded The logical RAID drive is operating in degraded mode.
Chapter 1 Drive Number and RAID Level The choice of RAID level for logical RAID drives depends on the number of drives within a drive group. The following table lists the RAID levels for drive group and RAID level requirements.

Chapter 5 Configuring the RAID Subsystem Interactively A number of tasks are required to configure your subsystem interactively. The procedures for these tasks are described in the following sections. Step 1 Action Create one or more drive groups. See Page P. 5-18 2 Create one or more logical RAID drives, including specifying their RAID levels and cache policy. P. 5-23 3 Designate a hot spare drive (optional) P. 5-25 4 Initialize each logical RAID drive. P.
StorageWorks RAID Array 200 Subsystem Family Creating a Drive Group A single controller can support up to eight drive groups. Remember these general rules when you configure your array: • Maximum number of drive groups: 8 • Maximum number of drives in each drive group: 8 • Maximum number of logical RAID drives: 8 The choice of RAID level for logical RAID drives depends on the number of drives within a drive group. This table shows the RAID levels for drive group/RAID level requirements.
Chapter 5 Understanding Drive Status The SWXCR controller assigns a drive status to each SCSI device. The drive status changes as you use the utilities. The utilities display the drive status as follows. Display FLD Drive Status Failed Meaning The device failed due to errors or you manually failed it. FMT Formatting The device is formatting. HSP Hot spare The device is configured as a hot spare (within a redundant RAID configuration) for use in an automatic rebuild in the event of a failure.
StorageWorks RAID Array 200 Subsystem Family To begin the configuration process, first you create a drive group. ______________________ NOTE____________________________ The total capacity of a drive group is determined by the member with the least capacity. If you are uncertain about the size of a particular drive, use the Device Information option on the Define Drive Group screen to check the size before you create a drive group.
Chapter 5 Figure 5-4 shows the New Configuration screen. From this screen, you can select the Define Group option, the Define Logical Drive option, or the Define Spare option. MRO230 Figure 5-4.
StorageWorks RAID Array 200 Subsystem Family Figure 5-5 shows the Define Drive Group screen. From this screen, you can create a drive group, cancel a group you created, arrange the drive group(s), and display information about your drive groups. MRO232 Figure 5-5.
Chapter 5 Step 3 4 Action Press the Enter key to select the Create Group option on the menu. Result The cursor moves to the drive matrix. Position the cursor on the drive you want to add to the drive group and press the Enter key. The system adds that drive to the drive group. The RDY (ready) status next changes to OPT (optimal). The drive is assigned a group letter and a sequence number. Add other drives to the drive group by repeating this step.
StorageWorks RAID Array 200 Subsystem Family Step 7 Action If the cursor is not on the Group Definition menu, press the ESC key. Then use the arrow keys to highlight the Arrange Group option and press the Enter key. Result The cursor moves to the drive pictorial on this screen. NOTE: In Step 8, when all drive groups are arranged, the system returns you to the New Configuration menu and highlights the Define Logical Drive option.
Chapter 5 Creating a Logical RAID Drive A logical RAID drive is presented to the host operating system as one physical drive. To the operating system, there is no difference between a controller logical RAID drive and a single physical drive on a conventional disk controller. A logical RAID drive consists of part or all of any drive group. ______________________ NOTE ____________________________ For a RAID 5 configuration, the controller must use some of the space for parity information.
StorageWorks RAID Array 200 Subsystem Family Step 6 7 Action Repeat this procedure for up to eight logical RAID drives, or until all the capacity of the selected drive group is used. Result Each new logical RAID drive is added to the table on the lower-left of the screen. Choose a caching policy. The default policy is Write-Thru (Through). The cursor moves to the right-hand column of the list of logical RAID drives and highlights the Write-Thru of the first logical RAID drive.
Chapter 5 Defining a Hot Spare Drive If your business cannot tolerate data loss or downtime due to drive failures, you should keep a drive available in the array as a hot spare for automatic rebuilds. Follow this procedure to create a hot spare drive. Step 1 Action Select the View Update option from the main menu. Result The system displays the View/Update Configuration menu as shown in Figure 5-8. 2 Select the Define Spare option. The system displays the Define Spare menu as shown in Figure 5-6.
StorageWorks RAID Array 200 Subsystem Family Figure 5-6 shows the Define Spare screen. In this example, you can only see Channel 0 because it corresponds to an SWXCR-EA 1-channel controller. If your RAID subsystem uses an SWXCR-EB 3-channel controller, the display would show channels 0, 1, and 2. Note that the drive in Target ID 4 of channel 0 in this example shows a drive status of HSP. This drive is defined as the hot spare. MRO234 Figure 5-6.
Chapter 5 Initializing a Logical RAID Drive Before you can use a logical RAID drive, it must be initialized to ensure consistent RAID parity information. For RAID levels that provide redundancy, this step is crucial to ensure that the RAID parity information is consistent from the beginning. _____________________ CAUTION ___________________________ Do not initialize a logical RAID drive if it has valid data. Initialization overwrites and destroys all data.
StorageWorks RAID Array 200 Subsystem Family To initialize a logical RAID drive, follow these steps. Step 1 Action From the main menu, select the Initialize Logical Drive option. Result The system displays the Initialize Logical Drive screen, showing each of the eight possible logical RAID drives. 2 You can initialize more than one logical RAID drive. Use the arrow keys to select the logical RAID drives you want to initialize and press the Return key.
Chapter 5 Saving the Configuration to a Diskette Digital strongly recommends that you save your configuration to a file on a diskette at this point. In the event that your controller fails, you need a backup of your configuration file in order to restore your original configuration on your new controller. You can use a formatted diskette or save the file to the diskette that you are using to run the utilities. To save the configuration, proceed as follows. Step 1 Action Insert the diskette.
StorageWorks RAID Array 200 Subsystem Family Figure 5-7 shows the Tools screen. From this screen, you can review the bad block table, list the error count, format a drive, change a drive status to optimal, fail a drive, back up or restore your configuration, clear your configuration, or print your configuration to a file. MRO233 Figure 5-7.

StorageWorks RAID Array 200 Subsystem Family Adding a Hot Spare Drive after Initial Configuration If your business cannot tolerate data loss or downtime due to drive failures, you should keep a drive available in the array as a hot spare for automatic rebuilds. If you plan to define one of your drives as a hot spare drive, you must do the following: 1. Exit the utility. 2. Insert the drive you want to designate as your hot spare drive. 3. Invoke the utility. 4.
Chapter 5 Failing a Drive A drive can fail due to errors on the device or because you manually failed it. If the utility records errors on a drive in your array, you may want to manually fail and then replace the drive before a permanent failure occurs. To fail a drive, proceed as follows. Step 1 Action Select the Tools option from the main menu. Result The system displays the Tools menu as shown in Figure 5-7. 2 Select the Kill Drive option. The system displays the drive matrix.
StorageWorks RAID Array 200 Subsystem Family Step 4 5-44 Action Press any key. Result The system displays a confirmation window. 5 Select Yes. The system spins down the drive. The status of the drive changes to FLD (failed). 6 Pull out the drive and replace it with a new drive. The system automatically rebuilds on the new drive.
Chapter 5 Manual Rebuild of a Drive (Reconstruction) A rebuild is a process of recreating data on a new drive in a configuration with a redundant RAID level (for example, RAID 1, RAID 0 + 1, and RAID 5). If your logical RAID drive was configured with a RAID level that does not support data redundancy, all data is lost if a drive fails. There are three ways to rebuild a drive.
StorageWorks RAID Array 200 Subsystem Family ______________________ NOTE____________________________ To minimize the chance of data loss due to a second drive failure, upon detection of a drive failure, replace the drive as soon as possible. To manually rebuild data of a failed physical drive (if you have not defined a hot spare drive), follow these steps. Step 1 2 Action Remove the failed drive from the RAID subsystem and replace it with a new drive.
Chapter 5 Viewing the Bad Blocks on a Drive During a rebuild, the bad block table receives entries from a rebuild with errors. If you are using the Rebuild option to rebuild a disk and the rebuild fails, the drive remains in the WOL (write only) state. You can use the Bad Block Table option to view the bad blocks. Step 1 2 Action Select the Tools option from the main menu. Result The system displays the Tools menu as shown in Figure 5-7. Select the Bad Block Table option from the Tools menu.
StorageWorks RAID Array 200 Subsystem Family Making a Drive Optimal In some circumstances described in the Troubleshooting Your Subsystem section of Chapter 6, you may have to use the Make Optimal option to change the state of a drive from failed (FLD) to (OPT) optimal. If you use this method to change the state of a drive instead of using the Rebuild option, the drive may contain faulty data.
Chapter 5 Restoring the Subsystem Configuration from a Diskette To restore your configuration information due to RAID controller replacement, use the file containing the configuration you saved on a diskette (the procedure for saving your configuration information was described earlier in this chapter). To restore the configuration, proceed as follows. Step 1 Action Insert the diskette. Result 2 Select the Tools option from the main menu. The system displays the Tools menu as shown in Figure 5-7.
