PhySIcAl DRIVe PRoBleMS
Physical drives are the foundation of data storage. A physical drive problem can affect your entire RAID system.
When a yellow ! icon or a red X icon appears beside a physical drive, check the drive’s operational status:
1. Click the Device tab.
2. Click the Physical Drive icon.
3. Click the physical drive you want, then click the View button.
Look under Operational Status for the condition of the physical drive.

Note 1: Clear the error condition. Then the physical drive is available. See “Clearing a Stale or a PFA Condition”
on page 186.
Note 2: Identify the disk array to which the physical drive belongs. Then delete the disk array. If the error
condition remains on the physical drive, clear the error condition.
Note 3: Obtain SAS-to-SATA adapters though PROMISE Technology, at
http://www.promise.com. See “Installing Your Drives” on page 36 for installation instructions.
Note 4: You can set the number of bad blocks tolerated before the controller marks a physical drive as Dead.
See “Managing Background Activities” on page 143, “Making PDM Settings” on page 154. See also “Running
Media Patrol on a Disk Array” on page 193 and “Disk Array Degraded / Logical Drive Critical” on page 632.
Caution
If there is unsaved data in the controller’s cache, the dirty cache
LED shines amber. During this time, do NOT power down the Vess.
Wait until the LED goes dark.
