2. Click Shrink and specify the following options for an LD shrink task.
3. Click Apply to view the current settings.
4. Click Confirm. The task starts.
Note
1. The new capacity must be bigger than the current capacity.
2. The sum of increased capacity of all logical disks on the disk group
must be less than or equal to the sum of capacity of all selected
free chunks.
Schedule Immediately: The task will start immediately.

chunks to be used for the expansion. The Ending
Free Chunk must be bigger than or equal to the

Background applies only to the logical disks with

DG ID/LD ID Select a DG ID and an LD ID from the drop-down
menu for shrink.
Capacity (MB) Enter the new capacity for the specified logical
disk to be shrunk. Note that the new capacity
must be higher than zero.
Note
It is advised that the file systems on the host be shrunk before
shrinking the logical disks; otherwise shrinking might cause data loss
or file system corruption.
