Description: SCSI Device Bus Parity Errors.
This is the number of parity errors seen on the SCSI bus while processing commands for this SCSI ID. This value is maintained since the SCSI Hardware Interface driver was loaded.
Parity errors may occasionally occur. If this value should rise dramatically, 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 cpqScsiTargetParityErrs?
This counter tracks parity errors seen on the SCSI bus while processing commands for this target's SCSI ID, maintained since the driver was loaded. A dramatic rise often points to bus-level issues like RFI, bad or missing terminators, or cabling problems rather than the device itself. For example, if targetParityErrs spikes right after a new cable was installed, the admin would check the termination and cable quality first.
