Enabling the Recovery
Advanced Software
You can enable the Recovery advanced software in MSM. When you enable Recovery,
you create two virtual drives, one as a Snapshot Base or a source and the other as a
Snapshot Repository. The base virtual drive contains the data that is stored in the
repository virtual drive.
Follow these steps to enable MegaRAID Recovery.
1.
Select the
Logical
tab on the main menu screen for the Logical view.
2.
Select and highlight a virtual drive from the list of virtual drives.
This is the Snapshot Base virtual drive.
NOTE:
A Base virtual drive and a Repository virtual drive can be associated with the
same drives or a common set of drives, or the two virtual drives can be located on two
completely separate set of drives. Using a separate set of drives for the Base virtual drive
and the Repository virtual drives provides a performance advantage over using a
common set of drives.

Select
Go To->Virtual Drive->Enable MegaRAID Recovery
on the menu bar, as
shown in
