Description: Tape Device Total Uncorrectable Errors.
This is the total number of read and write errors which could not be corrected. This value is maintained since the Tape Hardware Interface driver was loaded.
Errors may occasionally occur. If this value should rise dramatically, you may need to clean the device. If you continue to have errors, you may have a problem. Some common causes include radio frequency interference (RFI) on the bus cables, bad or missing terminating resisters on the drives or having more than one device with the same SCSI ID. Insure the bus cable is free of obstructions and that the devices on the bus are properly configured.
What is cpqTapeCountersTotalUncorrectable?
This counter tracks the total number of read and write errors on the tape device that could not be corrected at all, maintained since the Tape Hardware Interface driver was loaded. Because these are uncorrectable, a rising count is a stronger signal of real data-integrity risk than the correctable-error counters. For example, a nonzero and growing totalUncorrectable count would prompt the admin to verify the last several backup tapes were actually readable.
