Disk Array and Logical Drive Problems

Disk array and logical drive troubleshooting includes:

• “Disk Array Degraded / Logical Drive Critical”

• “DiskArrayOfine/LogicalDriveOfine”

• “RepairinganOfineDiskArrayorLogicalDrive”

• “Rebuilding a Disk Array”

• “Incomplete Array”

• “Unreadable Disk Warning”

Disk array problems typically result from a physical drive failure. The most common problem is a

degraded disk array. The RAID controller can rebuild a degraded disk array. See “Rebuilding a Disk

Array” on page 195.

Disk Array Degraded / Logical Drive Critical

Disk arrays are made up of physical drives. Logical drives are created on the disk array.

When one of the physical drives in a disk array fails:

• The operational status of the disk array becomes Critical.

• The operational status of the logical drives becomes Criticalor Degraded.

• The operational status of the physical drive becomes Deador Ofine. The Pegasus Utility reports

these conditions in the following places:

• Dashboard icon – A yellow ! icon beside the disk arrays, logical drives, and physical drives

under System Status.

• PhysicalDriveicon–PhysicaldrivesareshownDeadorOfineandmarkedwitharedX icon,

or Missing.

• Logical Drive icon – Disk Array and Logical Drive are marked Critical with a yellow ! icon.

RAID 6 logical drives are marked:

• Degraded with a yellow ! iconwhenONEphysicaldriveisofine.

• Critical with a yellow ! iconwhenTWOphysicaldrivesareofine.RAID0logical

drivesshowOfinestatusandaredX icon.

• Events icon – Logs a Major event for the logical drives and a Warning event for the physical drive.

If there is no spare drive in the Pegasus unit, you must provide the replacement drive. See “Replacing a

Physical Drive” on page 189.
