Error message types
553-4011-510 Standard 1.0 November 1994
SYSTEM V/68 error messages generally appear on the maintenance
display screen as they occur. There are some SYSTEM V/68 error
messages that do appear in the UNIX System Log. To find these messages
access the Display UNIX System Log in the same way as for SCSI I/O
error messages. If any SYSTEM V/68 messages do occur, report them
immediately to your NAC service representative.
This document frequently refers to contacting your Northern Telecom
service representative. This representative can be one of the following:
an on–site technician
a local distributor
the Northern Telecom support center
Several different error messages can be generated by the SCSI (Small
Computer System Interface) driver, the software, and the firmware
subsystem that drives SCSI devices, such as the hard disk and tape drive.
These error messages attempt to provide enough information to diagnose
and provide a solution to the problem. Most of these driver error messages
appear as a result of a failed hard drive or tape drive operation.
There are two types of error messages that may be encountered. These
types are recoverable and non-recoverable messages. A recoverable error
message has at least one solution or course of action available to correct the
problem. A non–recoverable error message usually signals that a serious
problem has occurred on the device. Depending on the severity of the
problem, corrective action may, or may not, be available to the user. Further
detailed diagnoses in cooperation with your Northern Telecom service
representative would be required to attempt a recovery from the error.
