The host computer
cannot communicate
with the library, or one
or more of the drives.
■ Make sure that the library is on-line.
■ This might be a SCSI bus time-out or a premature
disconnect problem.
■ Check cable connections, cable length, SCSI
addresses, and termination.
■ If the library is communicating via Fibre Channel,
then check for:
— Addressing issues
— Mapping issues
—Zoning
— Fibre Channel cable damage
— Proper installation and configuration of HBAs
— Up-to-date firmware and drivers
■ Restart the host and the library.
A tape cartridge is
reported as not
present.
Note: This message 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.)
■ Retry the command.
