Hello Andrew,
You can find in the output of a "lsscsi -l" command the timeout for your
drives. Then you can configure 3 timeout directives for each one of your
two drives (LRADrive-1 e LRADrive-2):
Maximum Changer Wait = X
Maximum Rewind Wait = X
Maximum Open Wait = X
where X is the timeout value for your dirves.
You can also customize your mtx-changer script for this timeout changing
the bellow 300 seconds value:
wait_for_drive() {
i=0
while [ $i -le 300 ]; do # Wait max 300 seconds
Best regards,
Ana
