In the Pegasus Utility, when a yellow ! icon or a red X icon appears beside a physical drive,
check the drive’s operational status:
1. Click the Physical Drive icon.
2. Mouse-over and click the physical drive you want then click the View button.
Look under Operational Status for the condition of the physical drive.
• Ofine– 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.
• Drive Failed or Dead – The physical drive cannot be repaired. You must replace the failed
drive.
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.
