Appendix B. TapeAlert Flags

This appendix is intended to provide additional information to the reader about
the tape drive. All error code and diagnostic information contained in this chapter
can be accessed from the Operator Panel of the Library. The drive portion of the
Operator Panel Display will contain any drive error codes. Therefore there is no
need to open the Library to access the buttons on the drive as described in this
chapter. See the Setup and Operator Guide for a complete description of the
Operator Panel functions and Displays.
TapeAlert is a standard that defines status conditions and problems experienced by
devices such as tape drives, autoloaders, and libraries. The standard enables a
server to read TapeAlert messages (called flags) from a tape drive via the SCSI bus.
The server reads the flags from Log Sense Page 0x2E.
This library is compatible with TapeAlert technology, which provides error and
diagnostic information about the drives and the library to the server. Because
library and drive firmware may change periodically, the SNMP interface in the
library does not require code changes if devices add additional TapeAlerts that are
not supported today. However, should this occur the MIB is written to minimize
impact to the SNMP monitoring station. At the time of this writing, the TapeAlert
flags in this appendix correctly represent TapeAlerts that will be sent. The MIB file
should not be taken to mean that all traps that are defined in the MIB will be sent
by the library or that they will be sent in the future.
This appendix lists TapeAlert flags that are supported by the Ultrium 3 Tape
Drives.

Flag
Number Flag
3 Hard error
4 Media
5 Read failure
© Copyright IBM Corp. 2005
Description
Set for any unrecoverable read,
write, or positioning error. (This flag
is set in conjunction with flags 4, 5,
or 6.)
Set for any unrecoverable read,
write, or positioning error that is due
to a faulty tape cartridge.
Set for any unrecoverable read error
where isolation is uncertain and
failure could be due to a faulty tape
cartridge or to faulty drive
hardware.
Action Required
See the Action Required column for
Flag Number 4, 5, or 6 in this table.
Replace the tape cartridge.
If Flag 4 is also set, the cartridge is
defective. Replace the tape cartridge.
If Flag Number 4 is not set, see Error
Code 6 in Drive Error Codes and
Messages.
