• Any virtual disk in the disk group is in any state of modification. • The controller that has ownership of this virtual disk is currently adding capacity to another virtual disk. Each controller can add capacity to only one virtual disk at a time. • No free capacity exists in the disk group. • No unconfigured capacity is available to add to the disk group. To expand the snapshot repository virtual disk from MD Storage Manager: 1 Click the Modify tab, then click Modify snapshot virtual disks. 2 Click Expand Snapshot Repository. 3 Click the snapshot repository virtual disk you want to expand. 4 If necessary, you can add free capacity to the volume group by adding an unassigned drive. To add an unassigned drive: a Click Add Drives. b Select the capacity to add from the drop-down menu. c Click Add. 5 Enter the amount by which you want to expand the snapshot repository virtual disk in the Increase capacity by field. 6 Click Finish to expand the capacity of the snapshot repository virtual disk. Re-creating Snapshot Virtual Disks Before re-creating a snapshot virtual disk, refer to the following guidelines. Disabling a Snapshot Virtual Disk Disable a snapshot virtual disk if one of the following conditions exists: • You do not need the snapshot now. • You intend to re-create the snapshot at a later time and want to retain the associated snapshot repository virtual disk so that you do not need to create it again. • You want to maximize storage array performance by stopping copy-onwrite activity to the snapshot repository virtual disk. The SMdevices utility displays the snapshot virtual disk in its output, even after the snapshot virtual disk is disabled. 80 Snapshot Virtual Disks
