HP autoloaders with firmware revision 9503 or later only: To allow
random access to tapes within the autoloader, you must add the “
lun=1
”
entry for each autoloader.
You may also like to make the following addition to your standard
configuration just above the
tape-config-list
entries:
tape-driver-buffering = 4;
This may improve the ability of your system to keep the drive streaming,
depending on your form of backup.
2 If you are replacing an existing tape device on the same SCSI ID, remove
the contents of the
/d ev / rm t
directory as follows:
% cd /dev/rmt
% rm *
3 Do a reconfigure boot:
% cd /
% touch /reconfigure
% sync;halt
4 When the system is down, reboot:
% boot -r
Make sure you include the
-r
switch, so that the device directory is
reconfigured using the new data.
5 You should now be able to use the drive.
