1 Understanding the Array Software Adaptec AHA-398x adapters use the following programs to create and manage arrays: ■ The Adaptec Initial Array Configuration Utility, which runs under DOS. Use this utility to create an initial bootable array to use as a boot device. (After arrays are created, they run under NetWare.) ■ The Adaptec Array Driver Copy Utility, which runs under DOS. Use this utility to copy DOS and NetWare drivers to your computer’s hard disk.
Initial Array Configuration Utility Follow these steps to create the first array with the Adaptec Initial Array Configuration Utility. For more detailed information on all Adaptec Initial Array Configuration Utility options, see the AHA-3980/3980W/3985/3985W User’s Guide. 1 Make a bootable copy of the Adaptec Initial Array Configuration Utility diskette. 2 Insert the diskette copy in the A drive and boot the computer. 3 When the computer has finished booting, type a:arconfig and press Enter.
When you have selected the number of disks you specified in step 7, the next screen appears. 10 If the array is mirrored or RAID 5 and at least one disk is unassigned, a prompt asks whether you want to choose a spare disk: If you do not want a spare: Type n. To select a spare: Type y. If prompted for the number of spares, type the number (1 or 2), and press Enter. Then follow steps 8 and 9 to select the spares. Note: A spare must have at least the capacity of the smallest disk in the array.
4 Array Driver Copy Utility The Adaptec Array Driver Copy Utility is on the AHA-3980/3985 Drivers and Raid Utilities diskette included with the AHA-398x adapter. You use this utility to copy DOS and NetWare drivers to your hard disk drive. These drivers are required to operate arrays under NetWare. You need the DOS drivers if you want to install NetWare or other software from a SCSI CD-ROM drive connected to your AHA-398x adapter.
2 Select the array for which you want to display the Main menu. The Main menu for that array appears. On systems with multiple arrays, the array status is indicated by the color of the array name that appears in the box to the left of the menus. Red means the array is off-line; yellow means the array has a down drive; green means the array is operating normally.
reassigned blocks), or Display Volume(s) on Array (list of partitions and volumes on the array. 4 When finished viewing the statistics, press Esc to display a pop-up menu, then select Quit. Verifying Arrays If a mirrored or RAID 5 array becomes inconsistent, data will be lost if an array drive fails. Follow these steps to verify the consistency of data on an array: 1 From the Main menu for the array, select Verify Functions. 2 Select Start Verify.
5 When prompted, type y to continue, or n to cancel the operation. To schedule a reconstruction, see Scheduling Tasks on page 8. Note: If you used Hot Swap Pause to stop SCSI bus activity, resume activity by pressing any key at the Administrator Utility screen. Reactivating an Off-line Array An array goes off-line if the power fails or if someone removes a second disk when one has already been removed. To reactivate an off-line array: 1 Physically correct the problem that caused the array to go off-line.
Scheduling Tasks You can schedule the following tasks: ■ Verifying mirrored and RAID 5 arrays ■ Testing spare disks ■ Reconstructing data on a replacement disk Follow these steps to schedule a task: 1 From the Main menu for the array, select Scheduler Functions. 2 Select Schedule Verify, Schedule Reconstruct, or Schedule Spare Testing. Note: If you schedule a verification, all arrays are verified. To verify only one array, follow the procedure given in Verifying Arrays on page 6.
Adding a Spare Disk If you create a mirrored or RAID 5 array without spare disks (RAID 0 arrays cannot have spares), follow these steps to add up to two spare disks later: 1 From the Main menu for the array, select Change Array Configuration. 2 Select Add Spare Drives. 3 If prompted to enter the number of spares, type 1 or 2 and press Enter. 4 Press Tab to select the channel with the spare disk(s). A list of disks on that channel appears to the right.
Converting between RAID 0 CVT and RAID 5 CVT Formats You can convert a RAID 5 CVT array to a RAID 0 CVT array and back again without loss of data and without reformatting. If you convert a RAID 5 CVT array with spares to a RAID 0 CVT array, the RAID 0 CVT array retains the spares, but they are not usable. When you convert the array back to a RAID 5 CVT array, the spares can again be used. To convert between formats, follow these steps: 1 From the Main menu for the array, select Convert RAID Level.
6 Menu Trees The following diagrams show the arrangement of menu options for the Adaptec Initial Array Configuration Utility, the Adaptec Array Driver Copy Utility, and the Administrator Utility.
