1 Read warning Set when the tape drive is having
problems reading data. No data has
been lost, but there has been a reduction
in the performance of the tape. Isolate the fault between drive and media
by doing the following:
• Use a known good tape cartridge in
the suspect drive.
• Use the suspect tape cartridge in a
known good drive. If the test fails,
discard the cartridge. If the test passes,
replace the drive.
2 Write warning Set when the tape drive is having
problems writing data. No data has
been lost, but there has been a reduction
in the capacity of the tape. Isolate the fault between drive and media
by doing the following:
• Use a known good tape cartridge in
the suspect drive.
• Use the suspect tape cartridge in a
known good drive. If the test fails,
discard the cartridge. If the test passes,
replace the drive.
3 Hard error Set for any unrecoverable read, write, or
positioning error. The flag is cleared
when the cartridge is removed from the
drive (this flag is set in conjunction with
flags 4, 5, or 6). Determine if flags 4, 5, or 6 exist; follow
the actions there.
