IBM Tivoli Storage Manager: Messages

Appendix C. I/O Error Code Descriptions for Server Messages

This section contains code descriptions for possible I/O error messages from the Tivoli Storage Manager server for the AIX and Windows NT^(R) operating systems.

Code

Description

OP

I/O operation that failed. Some possible values displayed are:

• READ
• WRITE
• FSR (forward space record)
• FSF (forward space file)
• WEOF (write end of file mark)
• A string of hex digits

  See Operation Code Values for Tape Library Devices for a list of operation codes.

CC

I/O completion code. This value is returned by the device driver to the server when an error occurs. See Completion Code and Operation Code Values for a list of completion codes. Refer to the IBM TotalStorage Tape Device Drivers Installation and User's Guide for information on tape library system calls and error description for the library I/O control requests.

KEY

Byte 2 of the sense bytes from the error. The following lists some definitions:
0 = no additional sense bytes available
1 = recovered error
2 = not ready
3 = medium error
4 = hardware error
5 = illegal request
6 = unit attention (for example, a SCSI bus reset)
7 = data protect
8 = blank check
9 = vendor specific
A = copy aborted
B = aborted command
C = equal compare on SEARCH DATA command
D = volume overflow
E = miscompare
F = reserved

ASC/ASCQ

Additional sense codes (ASC) and additional sense code qualifiers (ASCQ) are bytes 12 and 13 of the sense bytes. You should refer to the sense byte number along with the value for a complete description of the common values of the ASC and ASCQ codes. The drive or library reference manual provided with the device usually contain tables explaining the values of the KEY, ASC, and ASCQ fields. Common Values for ASC and ASCQ Codes also provides additional information on the common values of ASC and ASCQ.
