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 RS-422 interface. The
server reads the flags from Log Sense Page 0x2E. This appendix lists the TapeAlert
flags that are supported by the Ultrium Internal Tape Drive.

Flag
Number
Flag Description Action Required
3 Hard error Set for any unrecoverable read,
write, or positioning error. (This flag
is set in conjunction with flags 4, 5,
or 6.)
See the Action Required column for
Flag 4, 5, or 6 in this table.
4 Media Set for any unrecoverable read,
write, or positioning error that is due
to a faulty tape cartridge.
Replace the tape cartridge.
5 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.
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 12 on page 53.
6 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.
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 43). 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 12 on page 53.
8 Not data grade Set when severe servo errors occur
while loading a tape cartridge.
Replace the tape cartridge. If this
error occurs with multiple tapes, see
error code 6 in Table 12 on page 53.
9 Write protect Set when the tape drive detects that
the tape cartridge is write-protected.
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 43).
10 No removal Set when the tape drive receives an
UNLOAD command after the server
prevented the tape cartridge from
being removed.
Refer to the documentation for your
server’s operating system.
11 Cleaning media Set when you load a cleaning
cartridge into the drive.
No action required.
12 Unsupported format Set when you load an unsupported
cartridge type into the drive or when
the cartridge format has been
corrupted.
Use a supported tape cartridge.
