Description: External Array 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 the value cannot be determined, 4,294,967,295 is returned.
What is cpqFcaPhyDrvUsedReallocs?
This counter shows how many sectors of the drive's reallocation area have been used to remap bad sectors detected during normal operation. An admin tracks this over time because a rising count indicates the physical media is wearing out, and comparing it against the factory reallocation total (when available) shows how much spare capacity remains. For example, a steadily climbing value approaching the drive's known reallocation limit signals it should be scheduled for proactive replacement.
