Dell PowerVault TL4000 - Manual (Page 247)

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, 4, 5, and 6
Tape Drives.
TapeAlert Flags Supported by the Library
Parameter
Code
(d=decimal) Flag name Type Action Required
01d Library
Hardware A C The media changer mechanism is having difficulty communicating with
the drive.
Power cycle the library and try the operation again.
v If the problem is corrected, run Library Verify before resuming normal
library operations. Refer to “Service: Library Verify” on page 5-29.
v If the problem persists, contact technical support.
02d Library
Hardware B W There is a problem with the media changer mechanism. Power cycle the
library and try the operation again.
v If the problem is corrected, run Library Verify before resuming normal
library operations. Refer to “Service: Library Verify” on page 5-29.
v If the problem persists, contact technical support.
03d Library
Hardware C C The media changer has a hardware fault:
v Ensure that the media changer and drives are not being used by any
host, then reset the library from the front panel.
v If the problem persists, contact technical support.
