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.

All virtual drives that contain only SAS drives should have the drive write cache policy set to Disabled, by default. All virtual drives that contain only SATA drives should have the drive write cache policy set to Enabled, by default.

You can change a virtual drive’s Disk Cache Policy at any time after the drive is created. To do this, follow these steps:

  1. Select a virtual drive icon in the Logical tab of the left panel and then select Operations >> Set Virtual Drive Properties.
  2. Alternatively, click the Properties panel and then click Set Virtual Drive Properties.
  3. Change the Disk Cache Policy as needed in the right-hand panel.
  4. The options are Unchanged (unchanged from whatever the current cache policy is), Enabled, and Disabled.
  5. Click Go to accept the changes.
