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 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.
