Table 21 Problems
During Library
Operation
Problem Corrective Action
The host computer
cannot
communicate with
the library.
This may be a SCSI bus time-out or a premature
disconnect problem.
Check cable connections, cable length, SCSI
addresses, and termination.
Restart the host and the library.
If the host and library still are not
communicating, contact a field service engineer.
A cable or
terminator is
disconnected from
the SCSI bulkhead.
Reconnect the cable or terminator according to
the guidelines found in the cabling section in
Connecting Host Workstations on page 37
of this guide.
A tape cartridge
(medium) is
reported not
present.
This indicates that the gripper could not sense a
tape cartridge in a particular storage bin even
though the inventory reports that it is present.
Check to see if the designated cartridge is
present. If it is, make sure it is properly seated.
(For a tape drive, make sure the cartridge is
completely unloaded.) Then retry the
command.
If the error persists, contact a field service
engineer.
A move command
failed.
Check the source and destination bins. The
source bin should hold the cartridge to be
moved; the destination bin should be empty.
Make sure the gripper is empty and all
actuators are free of obstruction.
Also, make sure the library is on-line and the
Stop button is released.
Retry the command.
