Disks
 To move a managed disk from one disk folder to another
1 In the system tree, select a disk.
2 From the shortcut menu, select Move Managed Disk. The Move Managed Disk
window appears.
3 Select a folder to which you want to move the managed disks. Alternately, you can
create a new folder. See Creating a Disk Folder on page 131.)
4 Click Continue. The system asks you to confirm.
5 Click Yes (Move Now). You may have to refresh the browser before the disk appears in
the new folder.
6 The system asks you to rebalance the data on the disk. For more information on
rebalancing, refer to Rebalancing RAID on page 122
Releasing Disks
Releasing a disk removes it from the disk folder. You can only release a disk that contains
no user data. You can always release a spare disk.
 To release a disk from a folder
1 In the system tree, select a disk to be released. The Disk Information window
appears. Notice User Allocated Blocks. If the User Allocated Blocks field shows a
count more than 0:
a Move the disk to another folder. Refer to Moving a Managed Disk on page 127. Make
sure that you have a folder to which to move the disk and that there is enough free
space on the remaining disks in the folder to move the data. If necessary, create a
disk folder as described on Creating a Disk Folder on page 131.
b Rebalance the data among the disks remaining in the managed folder (as described
in Rebalancing RAID on page 122). Because rebalancing data occupies system
resources, you can rebalance immediately or schedule rebalancing for low-use
hours.
2 When the user-allocated block count is 0, from the shortcut menu, select Release
Disks. The user-allocated block is reduced to 0 only if there is enough space on the
remaining disks in the disk folder to accommodate the movement of data off that disk.
3 Click Yes to release the disk to the unassigned folder. The disk is released.
Deleting Disks
You cannot delete a disk unless it has failed and has no user allocated blocks or the disk
has been released. In the System Explorer window, a failed disk appears with a red dot. In
the Disk Information window status is reported as down and health is reported as failed.
 To delete a failed or released disk
1 In the Storage Management tree, select a disk.
2 From the shortcut menu, select Delete Disk.
