I guess the problem with using nsrjb is that it might not respond if
there's already a hung nsrjb process running, and that can happen, so
I'd like to be able to communicate directly with the picker without
using nsrjb -- some way to get around the hung nsrjb process without
rebooting the host. Trying to kill it does not always work.
We've had problems with the sg driver entry for the picker just
disappering on the Storagetek, and Legato needs this to be able to
comminicate with the Adaptec driver. So, for example, instead of inquire
reporting normal output like:
[email protected]:STK L80 0212|Autochanger
(Jukebox),/dev/sg0
[email protected]:SEAGATE ULTRIUM06242-XXX1522|Tape, /dev/nst0
[email protected]:SEAGATE ULTRIUM06242-XXX1522|Tape, /dev/nst1
[email protected]:SEAGATE ULTRIUM06242-XXX1522|Tape, /dev/nst2
[email protected]:SEAGATE ULTRIUM06242-XXX1522|Tape, /dev/nst3
you'll instead get something this:
NetWorker: SYSTEM error: could not determine SCSI ID/LUN for device
'/dev/sg0' (No such device)
[email protected]:STK L80 0212|Autochanger
(Jukebox),/dev/sg0
[email protected]:SEAGATE ULTRIUM06242-XXX1522|Tape, /dev/nst0
[email protected]:SEAGATE ULTRIUM06242-XXX1522|Tape, /dev/nst1
[email protected]:SEAGATE ULTRIUM06242-XXX1522|Tape, /dev/nst2
[email protected]:SEAGATE ULTRIUM06242-XXX1522|Tape, /dev/nst3
At this point, nsrjb isn't going to work, but I'm curious if the
utilities like movemd or sjimm, etc. would still be able to? Do they
communicate with the sg driver, too? Is there anyway to communicate
directly with the picker from the OS?
