Description: Physical Drive Used Reallocated Sectors.
This shows the number of sectors of the reallocation area that have been used by the physical drive.
To see how many sectors were originally available for use in the reallocation area, refer to the factory reallocation information if it exists. Not all drives support factory reallocation.
Because of the nature of magnetic disks, certain sectors on a drive may have media defects. The reallocation area is part of the disk drive that the drive manufacturer sets aside to compensate for these defects. The drive array controller writes information addressed from these unusable sectors to available sectors in the reallocation area. If too many sectors have been reallocated, there may be a problem with the drive.
If you suspect a problem, schedule server down time to run diagnostics to verify that a problem exists.
What is cpqDaPhyDrvUsedReallocs?
This shows the number of sectors from the drive's factory reallocation reserve that have actually been used to remap bad sectors, and is compared against the original factory-reallocation total to gauge remaining spare capacity. An admin treats a rising trend here as an early sign of a drive's magnetic media degrading, since increasing reallocation usage often precedes an eventual failure. For example, cpqDaPhyDrvUsedReallocs climbing rapidly on one drive relative to its peers signals the admin to proactively replace that disk before it fails outright.
