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.

CAUTION: 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, as

shown in the following figure.
