Changing Virtual Drive Properties

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.

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.

You can change a virtual drive’s Read Policy, Write Policy, and other properties at any time after the drive is created. To do this change, follow these steps:

  1. Select a virtual drive icon in the Physical tab or the Logical tab in the left panel of the MegaRAID Storage Manager main menu screen.
  2. Select Go To->Virtual Drive->Set Virtual Drive Properties from the menu bar.
  3. The Set Virtual Drive Properties dialog box appears.
  4. Change the Disk Cache Policy in the drop-down menu.
  5. The options are Unchanged (unchanged from whatever the current cache policy is), Enabled, and Disabled.
  6. Click Ok to accept the changes.
