We are ACSLS 5.3, AIX 4.3.x, ADSM 3.1.x or TSM 3.7.2.
STK 9710 libraries with STK9840 drives.
In our systems ACSLS is installed on the same host as TSM, but it doesn't
have to be that way.
We are all SCSI, no fiber. Each tape drive still has it's own SCSI address,
and the robot has a SCSI address, too.
(Depending on your setup, the connection for the robot can be serial
instead of SCSI.)
The only thing that flows to ACSLS is the robotic commands.
Data still flows on the SCSI bus directly to the drive.
A logical view of how it works: Whenever TSM has a command to send to the
robot arm, instead of sending the SCSI commands down the bus to the robot,
it changes the command into something that works sort of like an RPC call
that goes over to the ACSLS software, then ACSLS issues the SCSI commands to
the robot arm.
Once the tape is mounted, TSM sends the data out the SCSI bus to the
appropriate drive address, just like it would in any other SCSI setup.
ACLS libraries (which most TSM documentation calls ACS libraries) have
weird restrictions on checkin and checkout (don't ask me why, I can't
understand what the problem is). Other than that, it works fine.
I have included my DEVCLASS Definitions below. The CE who hooks up your
robot will be the one to tell you which robot address (the ACSDRVID) matches
which AIX address.
Does that answer any questions for you?
