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 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 200/400GB LTO-2 Tape Drive.

Flag
Hard error
Set for any unrecoverable read,
write, or positioning error. (This
flag is set in conjunction with
flags 4, 5, or 6.)
Media
Set for any unrecoverable read,
write, or positioning error that is
due to a faulty tape cartridge.
Read failure
Set for any unrecoverable read
error where isolation is uncertain
and failure could be due to a
faulty tape cartridge or to faulty
drive hardware.
Write failure
Set for any unrecoverable write
or positioning error where
isolation is uncertain and failure
could be due to a faulty tape
cartridge or to faulty drive
hardware.
Not data grade
Set when severe servo errors
occur while loading a tape
cartridge.
Write protect
Set when the tape drive detects
that the tape cartridge is
write-protected.
No removal
Set when the tape drive receives
an UNLOAD command after the
server prevented the tape
cartridge from being removed.
Description
See the Action Required column
for Flag 4, 5, or 6 in this table.
Replace the tape cartridge.
If Flag 4 is also set, the cartridge
is defective. Replace the tape
cartridge. If Flag 4 is not set, see
error code 6 in Table 8 on
page 49.
If Flag 9 is also set, make sure
that the write-protect switch is
set so that data can be written to
the tape (see "Setting the
write-protect switch" on
page 16). If Flag 4 is also set, the
cartridge is defective. Replace
the tape cartridge. If Flag 4 is
not set, see error code 6 in
Table 8 on page 49.
Replace the tape cartridge. If this
error occurs with multiple tapes,
see error code 6 in Table 8 on
page 49.
Make sure that the cartridge's
write-protect switch is set so that
the tape drive can write data to
the tape (see "Setting the
write-protect switch" on
page 16).
Refer to the documentation for
your server's operating system.
