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. Mouse-over the physical drive you want and click the View button.
Look under Operational Status for the condition of the physical drive.
• Offline – Check the drive for:
• PFA Condition – Caused by a bad block or sector. See Note 1
below.
• Stale Condition – Caused by obsolete array information on the
physical drive. See Note 2 below.
• Not Usable – This condition occurs when you have:
• Two controllers in your RAID subsystem and a SATA drive without a
SAS-to-SATA adapter. See Note 3 below.
• A missing or defective SAS cable between the RAID subsystem
and a JBOD expansion unit.
• Drive Failed or Dead – The physical drive cannot be repaired. You
must replace the failed drive. See Note 4 below.
Note 1: Clear the error condition. Then the physical drive is available. See
“Clearing a Stale or a PFA Condition” on page 120.
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 Physical Drives” on page 19 for
installation instructions.
Note 4: You can set the number of bad blocks tolerated before the controller
marks a physical drive as Dead. See “Making PDM Settings” on page 97 or
“Making Background Activity Settings” on page 208.
