.)
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
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
). 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.
