The Snapshot Repository table displays the details of the default virtual drives existing in the system, if there are any.

*

Name – Displays the name of the virtual drive.

*

Status – Displays the status of the virtual drive.

*

Available Capacity – Displays the available capacity on the virtual drive.

*

Total Capacity – Displays the total capacity of the virtual drive.

If the default virtual drives do not exist in the system, the columns in the Snapshot Repository table are blank.

The status of the virtual drive can be optimal, degraded, or partially degraded.

2.

In the Select Capacity field, use the drop-down list to select the appropriate capacity to use for changes to the base virtual drive.

The capacity depends on how write-intensive the application snapshots are. The available capacity is the largest free block of capacity on the snapshot repository virtual drive.

NOTE  Refer to the tips provided for allocating capacity in the previous figure.

NOTE  If you designate all of the capacity for the virtual drive repository, you cannot use the same virtual drive as a repository for other volumes.

3.

Click Next.

The Enable MegaRAID Recovery - Displaying the Selected Virtual Drive wizard appears. This wizard lets you select the virtual drive to be used as the snapshot repository.
