Appendix C. TapeAlert Flags

This appendix is intended to provide additional information to the reader about the 
tape library and tape drive. All error code and diagnostic information contained in 
this chapter cannot be accessed from the Operator Panel of the Library. The Operator 
Panel will, however, display other library error codes and drive error codes when 
problems occur. For a listing of Operator Panel error messages, see Appendix B, 
“Error Codes,” on page B-1.

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. 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.
