Hi,

Question here on using manual operations to clean a drive, e.g. inventory.

When a drive on our tape library indicates that it needs to be cleaned (red led light), I usually run sjimm (or mtx) and move the cleaner tape from a designated slot into the device; it cleans, ejects, and then I run the same command to move it back to the designated slot - all well and fine.

HOWEVER, what if a NW administrator needs to clean a drive, but they don't have permission to run sjimm or mtx to manually move a tape into a drive? Obviously, they can just open the door to the tape library and manually insert the tape into the drive, but I was wondering if they could simply inventory the slot (from NW) that the cleaning cartridge is in?

I'm thinking that they can't use 'load' or 'load without mount' because both of these options will expect there to be a label on the tape or at least expect it to be a known NW volume before it loads it, which a cleaner is not. On the other hand, they could do an inventory, but when a cleaner tape is inserted into a drive, the drive automatically ejects it when it's done cleaning, but NW will also want to tell the drive to eject the tape when it's done inventorying it, so I'm thinking NW might wait, and then try to eject it, but it won't be able to because the drive will have already ejected it, and an 'invalid argument' error might result? At that point, the operator wouldn't be able to move the tape back to the slot since it's not completely in the drive.
