Thanks for the "explanations" but I still don't understand. Does the fibre

need IP for CLI?
Yes, the TSM server will be configured to talk to the Library Manager of
the 3584 via scsi LUN1 of your tape drives, where scsi LUN0 is the
drive. The 3584 is a typical SCSI tape library. The IP access to the
3584 is for Administrative access to the LM, and will be on port 80 of
the IP address assigned to the LM. This is used for configuring the
library, installing code updates, etc. Via this access, you can
enable/disable the control port on the drives in the logical library.
At least one is required, and the rest are optional, and can be used for
"control point failover". If you enable the control point on a drive,
you then need to go to your TSM server, and discover this device in the
OS (cfgmgr in AIX). Atape on AIX will configure an additional smc
instance (rmtX are the drives). You will not use ibmatl for the 3584.
Within TSM, you will drive your library to use the smc device. Something
like this:
define library 3584 libtype=scsi shared=no
define path tsmt 3584 srctype=server desttype=library device=/dev/smc4
define drive 3584 d1 online=yes element=257 cleanfreq=none
define drive 3584 d2 online=yes element=258 cleanfreq=none
define drive 3584 d3 online=yes element=259 cleanfreq=none
define drive 3584 d4 online=yes element=260 cleanfreq=none
define path tsmt d1 srctype=server desttype=drive library=3584 -
device=/dev/rmt4 online=yes
define path tsmt d2 srctype=server desttype=drive library=3584 -
device=/dev/rmt5 online=yes
define path tsmt d3 srctype=server desttype=drive library=3584 -
device=/dev/rmt6 online=yes
define path tsmt d4 srctype=server desttype=drive library=3584 -
device=/dev/rmt7 online=yes
You can determine the element numbers of each drive via the Admin login
to the 3584.
I think in Linux you will install IBMtape for both the smc and rmt
device drivers.
Hope this makes sense, and helps.

Are the drives still separate when it comes to paths (other than being
defined as part of a library)? Is the fibre connection to the library the
way the library communicates with the drives (like the old RS422 in the
3494)? or how the TSM library manager server communicates with the
library/TS3500?
With the 3494, you used a driver called ibmatl which used /etc/ibmatl.conf
(this is RedHat Linux) to define the IP/host connection to the library.
How do you configure a TS3500?

The book talks about "*to communicate with a server, the IBM System

TS3500 Tape Library uses a Fibre Channel interface (also called a
port).*"
Why? What is this "fibre channel interface" used for? The 3494 use IP
to
communicate/manage the library and the drives inside the library used
fibre
plus an RS422 connection to the library manager.
Because that is the way a 3584 works…. 'in band'. leftovers from when the
3584 was still midrange and midrange libraries are controlled in band. BTW,
with modern ts3500's features like control path failover are inclusive and
losing one tape drive does not mean that the library is uncontrollable.
