Solving Common Tape Subsystem Problems
For more information about common problems that can occur with tapes unloaded by
the system, see
Handling Tapes Unloaded by the System on page 10-28.
Table 10-3. Common Tape Subsystem Problems (page 1 of 2)
Problem Possible Causes Solution
Hardware:
A device is not ready, resulting
in error 100. A tape drive was brought
down or is not online. Power up the drive and/or
put it online.
A device has been brought down
or a hardware failure has
occurred, resulting in error 66. A tape drive has been
purposely brought down. Bring the drive up and
retry.
An interrupt timeout occurs,
resulting in error 218. An I/O process cannot
communicate with a tape
drive (often due to a
controller failure). Notify your management.
Software:
File-system error 195 occurs,
indicating that $ZSVR is not
running. The $ZSVR process has
been purposely stopped. Restart $ZSVR if you have
the authority, or escalate
the problem.
Tape:
No write-enable ring has been
installed on a tape. An incorrect tape was
mounted or a write-enable
ring was not installed. Verify that it is the correct
tape, install a write-enable
ring, and remount the tape.
A runaway tape was detected, or
an attempt was made to access a
tape whose density is lower than
the switch setting on the tape
drive. An error 151 results. The system has tried to read
a blank tape or a tape
written at a density lower
than the drive can read. Check the tape and replace
it if needed, change the
density switch, or mount
the tape on a different
drive.
A tape continues to spin beyond
the load point. The load point has fallen
off. Use a new tape.
Every time a tape is mounted, it
is unloaded. The drive on which the tape
is mounted is open for
unlabeled use and a labeled
tape is being mounted. Unload the tape by using
MEDIACOM or mount an
unlabeled tape.
Security:
A security violation has
occurred, resulting in error 48. An attempted operation was
not allowed. Resecure necessary files if
you are authorized, or
notify management.
Tape DEFINE:
The DEFINE you specified
could not be found, resulting in
error 198. The specified DEFINE
name does not exist. Correct the DEFINE name
used in syntax or supply a
DEFINE of the given name.
