Appendix. Tapealert Flags - IBM TotalStorage Ultrium T800 Operator's Manual

Appendix. 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 TotalStorage Ultrium 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 drive detects that
the tape cartridge is
write-protected.
No removal Set when the drive receives an
UNLOAD command after the
server prevented the tape
cartridge from being removed.
Cleaning media Set when you load a cleaning
cartridge into the drive.
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 15 on page
75.
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 "Write-Protect
Switch" on page 55). 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 15 on page
75.
Replace the tape cartridge. If this
error occurs with multiple tapes,
see error code 6 in Table 15 on
page 75.
Make sure that the cartridge's
write-protect switch is set so that
the drive can write data to the
tape (see "Write-Protect Switch"
on page 55).
Refer to the documentation for
your server's operating system.
