Physical Drive Problems

Physical Drive Offline

Check the drive for:
• PFA Condition – Caused by a bad block or sector.
See "Clearing Stale and PFA Conditions" on page 147 (WebPAM PROe) or
page 227 (CLU).
• Stale Configuration – Caused by obsolete array information on the physical
drive. Identify the disk array to which the physical drive belongs. Then delete
the disk array. See "Deleting a Disk Array" on page 158 (WebPAM PROe) or
page 234 (CLU).
If the error condition remains on the physical drive, clear the error condition.
See "Clearing Stale and PFA Conditions" on page 147 (WebPAM PROe) or
page 227 (CLU).

Physical Drive Not Usable

This condition occurs when you have a missing or defective SAS cable between
the VessRAID subsystem and a VessJBOD expansion unit.

Physical Drive Failed

When physical drive status shows failed, the physical drive cannot be repaired.
You must replace the failed drive.
Physical Drive Fails during Migration
VessRAID has two methods for migrating a disk array:
• DDF – The default setting. Slower but reliable
• NVRAM – An optional setting that requires special access. Faster but risks
data loss
Normally, RAID level migration is done under the default Disk Data Format (DDF)
setting. If a physical drive or the controller fails during migration, the disk array
goes critical, and you can rebuild it. Migration under DDF can take up to several
hours depending on the number and size of the physical drives and data input/
output activity.
VessRAID supports disk drive hot-swapping. To avoid hand
contact with an electrical hazard, do not remove more than one
drive carrier a time.
