I have 4 superdlt drives in an L700 configured for multihosted
environment (with SSO). The drives are connected via a scsi-to-fiber
bridge (crosspoint 4200, to be specific). As I understand it, SDLT
drives clean themselves, for that reason, I don't have cleaning tapes in
the robot. I've observed that whenever nbu tries to clean the drives,
all the drives stop responding to nbu commands; thus backups or restores
will sit, while netbackup waits for a response from the drives, which
never comes. The only way to recover from this is by entirely rebooting
the machine.
Has anybody else experienced this behaviour? I figure if I can stop nbu
from attempting to clean the drives all together, the drives then
wouldn't hung. Is there a bp.conf option, or some other option that
completely disables any sort of cleaning of the drives?
thanks
robert
