Changing Virtual Drive Properties

You can change the read policy, write policy, and other virtual drive properties at any time after a virtual drive is created.

ATTENTION  Do not enable drive caching on a mirrored drive group (RAID 1 or RAID 1E). If you do, data can be corrupted or lost in the event of a sudden power loss. A warning appears if you try to enable drive caching for a mirrored drive group.

NOTE  For virtual drives with SAS drives only, set the drive write cache policy set to Disabled, by default. For virtual drives with SATA drives only, set the drive write cache policy to Enabled, by default.

To change the virtual drive properties, perform the following steps:

1.	Select a virtual drive icon in the Physical tab or the Logical tab in the left panel of the MegaRAID Storage Manager window.

2.	Select Go To > Virtual Drive > Set Virtual Drive Properties from the menu bar.

The Set Virtual Drive Properties dialog appears, as shown in the following figure.

NOTE  If the controller supports High Availability DAS, the Provide Shared Access check box appears in the above dialog. Select this option if you want the virtual drive to be shared between the two servers in a cluster.

3.	Change the virtual drive properties as needed.

For information about these properties, see Selecting Virtual Drive Settings.

4.	Click OK to accept the changes.

The virtual drive settings are updated.
