Changing a Virtual Drive Configuration
9.8.5 Migrating the RAID Level of a Virtual Drive
As the amount of data and the number of drives in your system increase, you can use RAID-level migration to change
a virtual drive from one RAID level to another. You do not have to power down or reboot the system when you make
this change.
When you migrate a virtual drive to another RAID level, you can keep the same number of drives, or you can add
drives. In some cases, you have to add a certain number of drives to migrate the virtual drive from one RAID level to
another. The window indicates the minimum number of drives you are required to add.
CAUTION Be sure to back up the data on the virtual drive before you change the
RAID level.
Follow these steps to change the RAID level of the virtual drive with the Modify Drive Group wizard:
1. Click the Logical tab in the left panel of the MegaRAID Storage Manager window.
2. Select a drive group in the left panel of the window.
3. Either select Go To > Drive Group > Modify Drive Group on the menu bar, or right-click the virtual drive icon to
access the Modify Drive Group wizard.
The Modify Drive Group wizard appears.
