5. To add one or more existing repository virtual disks, perform the following steps:

a) Select one or more repository virtual disks from the Eligible repository virtual disks table.

The eligible repository virtual disks that have the same DS settings as the associated base virtual
disk are only displayed.

NOTE: You can click the Select all check box to add all the repository virtual disks displayed
in the Eligible repository virtual disks table.

b) Select Allow mismatch in DS attributes to display additional repository virtual disks that do not

have the same DS settings as the base virtual disk.

6. To create a new repository virtual disk, perform the following steps:

a) From the Create New Repository On drop-down list, select a disk group or disk pool.

The drop-down lists only the eligible repository virtual disks that have the same DS settings as the
associated base virtual disk. You can select Allow mismatch in DS attributes to display additional
repository virtual disks that do not have the same DS settings as the base virtual disk.
If free capacity is available in the disk group or disk pool you selected, the total free space is
displayed in the Capacity spinner box.

b) If required, adjust the Capacity.

NOTE: If free capacity does not exist on the disk group or disk pool you selected, the free
space that appears in the Capacity spinner box is 0. If this storage array has Unconfigured
Capacity, you can create a new disk group or disk pool and then retry this operation using
the new free capacity on that disk group or disk pool.

7. Click Increase Repository.

The system performs the following actions:

– Updates the capacity for the repository.
– Displays the newly-added repository member virtual disk(s) for the repository.

Decreasing The Capacity Of The Overall Repository

An overall repository can contain multiple repository virtual disks.
Use the Decrease Capacity option to decrease the storage capacity of an existing overall repository for
the following storage objects:

• Snapshot group
• Snapshot virtual disk
• Consistency group member virtual disk
• Consistency group member snapshot virtual disk
• Replicated pair virtual disk

You cannot decrease the storage capacity of the overall repository if one of these conditions exists:

• The overall repository contains only one repository member virtual disk.
• If there are one or more snapshot images associated with the overall repository.
• If a snapshot virtual disk or a consistency group member snapshot virtual disk is disabled.

The following guidelines apply:

• You can remove repository member virtual disks only in the reverse order that they were added.
• An overall repository must have at least one repository member virtual disk.
