The virtual I/O slots can be very confusing.
One time we filled our library up due to needing as many tape as possible.
Every slot was full with either a real tape or cleaning cartridge. Later
we tried to eject a tape that was bad. The checkout cmd failed. Long
store short - there were no open slots in the library, and this made it so
the checkout couldn't move the tape to to the virtual export slot, which
would have put the tape in the CAP. I really don't understand this - you
would think it could checkout a tape into the CAP door without needing
open slots. After we removed a cleaning cartridges (freeing up one
slot), the checkout worked correctly. From what we understand, you need
as many open slots in the library as you have virtual I/O slots (CAP door
slots), or at least for as many tapes you would want to checkout
concurrently.
At least that's what we think happened, which could very well be wrong! As
I said, I've found this confusing. The manuals for the 3584 don't really
explain this interaction.

The "virtual I/O slots" only get involved when you put cartridges in
through the 16/32 slot physical I/O door.
For the initial library load, just open the BIG doors and put the tapes
directly into the slots yourself.
Then for a SCSI library, the syntax for CHECKIN is slightly different than
for your 3494.
checkin libv bubba search=yes status=scratch checklabel=barcode waitt=0
volrange=TS1000,TS1999
checkin libv bubba search=bulk status=scratch checklabel=barcode waitt=0
Search =YES tells TSM to checkin from the INSIDE library slots.
Search=bulk tells TSM to checkin what's in the I/O door (with ALMS, it's a
virtual I/O door, but TSM doesn't' know that.)
FWIW:
For the 3494, TSM just tells the 3494 what it wants done, and doesn't know
or care where in the library tapes are located.
All the inventory management is done outboard by the 3494.
If TSM tells the 3494 to mount a cartridge, he doesn't need to know where
the cartridge is, that's handled by the 3494
For a SCSI library, including the TS3500 doing business as a 3584, TSM has
to figure out what tapes are in what slots at checkin time, and saves the
slot numbers in devconfig so he can send the appropriate commands for
cartridge movement. (e.g., take cartridge from slot 1024, load in drive
position 6). That's why the checkin commands are different.

Again thank you for this additional useful piece of information. But now
this brings up another issue/question.
If I am limited to no more than 255 unassigned tapes, how do I do a
mass/bulk checkin of my 1200 plus tapes we are transferring from the 3494?
