Installation CAUTION Do not proceed to the next step if any LUN is not in an optimal state and you intend to move any of the disks which comprise the LUN. Contact HP Support if the LUNs cannot be made OPTIMAL before the moving disk drives. 3. If you intend to move any global hot spares, remove them from the hot spare group as follows: a. Verify that the hot spare disk to be moved is not in use. b. Remove the disk from the hot spare group. 4. Unmount any file systems associated with the disk array. When the file systems are no longer mounted, continue with the next step. Step 4.
