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 since the SCSI Interface Module 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 cpqSbDevParityErrs?
This counter tracks parity errors seen on the SCSI bus while processing commands for this device's SCSI ID, since the SCSI Interface Module was loaded. A dramatic rise points to bus-level issues such as RFI, bad or missing terminators, or too many devices on the bus. For example, a device showing a sudden jump in parityErrs after adding another device to the same bus would suggest the bus is now over-terminated or overloaded.
