IBM T400F manual Appendix B. TapeAlert Flags, TapeAlert Flags Supported by the Drive, Description

Appendix B. TapeAlert Flags

TapeAlert is a patented technology and standard of the American National Standards Institute (ANSI) that defines conditions and problems that are experienced by tape drives. The technology enables a server to read TapeAlert flags from a tape drive through the SCSI, Fibre Channel, or Library/Drive Interface (LDI or RS-422 interface). The server reads the flags from Log Sense Page 0x2E. This appendix lists the TapeAlert flags that are supported by the IBM TotalStorage LTO Ultrium 2 Tape Drive.
