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 Control Panel of the Library. The drive portion of the Operator Control 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. 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 Management Information Block (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 (refer to Appendix F, "SNMP Status MIB Variables and Traps," on page F-1) 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 and Ultrium 4 Tape Drives.

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 Control Panel of the Library. The drive portion
of the Operator Control 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.
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 Management Information
Block (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 (refer to Appendix F, “SNMP Status MIB
Variables and Traps,” on page F-1) 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 and
Ultrium 4 Tape Drives.
