Chapter 6: Troubleshooting and Maintenance
If you cannot read or write tapes in the DLT2000XT tape drive even though it is listed in
hinv, it is possible that the device driver was not properly created during system bootup.
You can determine the status of the available system drivers by entering
% ls /dev/mt
To determine the status of a DLT2000XT tape drive, enter
% mt -t /dev/mt/*device* stat
You can try manually making the device by becoming root and using the following
commands:
% su
# cd /dev
# MAKEDEV tape
# exit
Reboot the host system and try hinv -c tape again. After trying all the troubleshooting tips
in this section and checking all the solutions listed in Table 6-1, contact your system
administrator or service provider if the system still does not recognize or allow access to
the DLT2000XT tape drive.
