Using the MegaRAID Advanced Software : MegaRAID Recovery : Snapshot Repository

Snapshot Repository

You can select an existing virtual drive, or create a new virtual drive to use as the snapshot repository.

Use any one of the options to select or create a new virtual drive.

Select the virtual drive to use as the Snapshot Repository in the Snapshot Repository field from the Enable MegaRAID Recovery Wizard wizard as shown in the following figure.

Click Create New to create a new virtual drive to use as the Snapshot Repository.

When you create a new virtual drive, the newly created virtual drive gets appended to the existing rows in the Snapshot Repository field.

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

The Name column displays the name of the virtual drive.

The Status column displays the status of the virtual drive.

The Available Capacity column displays the available capacity on the virtual drive.

The Total Capacity displays the total capacity of the virtual drive.

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

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

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

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

NOTE Please refer to the tips provided for allocating capacity in the following figure.

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.
