2.7.6 Expanding volumes

To expand the capacity of a volume, do the following:

1. Select Maintenance Utilities > VOL Reconfiguration from the main menu.

2. Select Expand and specify the following options for a VOL expansion task. The expansion volume is formed by

concatenating new logical disks.

3. Click Apply to view the current settings.

4. Click Confirm to continue the expansion.

2.7.7 Shrinking volumes

The shrink operation conducts without background task; it simply reduces the capacity of the volume by removing the

concatenating volume units.

To release free space of a volume, do the following:

1. Select Maintenance Utilities > LD Reconfiguration from the main menu.

2. Select Shrink and specify the following options for a VOL shrink task.

3. Click Apply to view the current settings.

4. Click Confirm to continue the shrink.

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.

VOL ID Select a VOL ID from the drop-down menu for expansion.

LD Level Select a RAID level to filter a list of expanding LDs.

Expanding LDs Select and use the arrow buttons to move one or more LDs from the Available LDs

list to the Expanding LDs list.

Note

1. The volume must be in optimal state.

2. The maximum number of member logical disks for each volume is eight.

3. No two logical disks can be in the same disk group.

4. None of the logical disks can be used by other volumes.

5. None of the logical disks can be bound to any LUNs.

6. All logical disks must be in the optimal state.

7. All disk groups of the logical disks must belong to the same owner controller.

VOL ID Select a VOL ID from the drop-down menu for shrink.

Shrinking VUs Select member VUs you want to remove from the list and use the arrow buttons to

move them to the Shrinking VUs list.

Note

1. The volume must be in optimal state.

2. There must be at least two concatenating volume units in a volume.

3. All selected volume units must be the last concatenating volume units in the volume.
