Using AutoRAID Manager for Windows NT Adding a Disk 5. Click Delete. Adding a Disk At some time you will probably want to add another disk to your array. Features such as hot-plug disk modules and Auto Include simplify the process of adding a disk to the array, even while the disk array is operating. A disk can be added to the array without disrupting client or host operation. After you have added a new disk, you have three options on how to use it: • Increase capacity - you can use the disk to increase the capacity available to the operating system by creating a new logical drive. • Improve performance - you can use the disk to improve disk array performance by simply leaving it as unallocated capacity. • Enable Active Hot Spare - you can use the additional capacity to enable Active Hot Spare if your disk array does not currently have the capacity to implement this feature. NOTE! The Auto Include feature will normally include the disk drive when it is installed. However, in some situations, the array will not include a disk automatically, even if Auto Include is enabled. In this case, you must manually include the disk. For more information on Auto Include, see the "Concepts and Management" chapter in the HP SureStore E Disk Array 12H User's and Service Manual. To add a disk to increase capacity: 1. Make sure the new disk has been installed in the array cabinet. 2. Click the disk array from Detail pane. 3. If Auto Include is on, the disk is automatically added to the array and you can proceed to step 4. If Auto Include is off, manually include the disk as described in "Including a Disk Manually." 4. Create one or more logical drives using all or a portion of the disk's capacity. 5. Perform the necessary steps to configure the new logical drive into your host. This is typically done using the Windows NT Disk Administrator. Refer to Windows NT Help for information on performing this task. To add a disk to improve array performance: 1. Make sure the new disk has been installed in the array cabinet. 2. Right-click the disk array from the Detail pane. 228 Windows NT
