Hi Bill,
I was aware of the limitations on partitioning, but I couldn't tell for
sure from the book whether we could mix SCSI and Fibre.  
What my customer wants to do is EXACTLY what you are doing, add an LTO3
but keep the LTO1.
THANK YOU!

Wanda

Wanda,
        Here's link to the doc for the 3583 library:
http://www-1.ibm.com/support/docview.wss?rs=547&context=STCVQ6Y&dc=DA400
&q1=ssg1*&uid=ssg1S7000640&loc=en_US&cs=utf-8&lang=en

You can partition the library, but there are some strict rules on how.
Not as granular as partitioning the 3584.

You can mix and match the drives in the library, as well as
connectivity. I havea 3583 with 3 LTO-1 SCSI drives and 1 LTO-3 fibre
drive. I don't have the library partitioned and ran into some "issues"
with this and TSM. Ended up having an APAR written to update
the documentation on multi-media support in TSM. That's a whole other
story! But what TSM changes was to get "full" support of
multi-media in the same library you should partition the library. I
elected not to do that and just live with the limitations.

Read Chapter 2 on installation planning. There's a section on how many
partitions and how many columns are required.

For each logical library you will have a control point. That control
point is seen by the host as a /dev/smcx or lbx.x.x.x. So 2
partitions, 2 libraries at the host.

I've never done this with a 3583 before.

Does anybody know (or can you point me to the doc), when you partition
the 3583, if you connect both partitions to the same host,
does the 3583 present a new/second LBx.x.x.x address to Windows?  (Or a
new /dev for AIX).

And if you have 2 partitions with different devices (LTO1 in partition
A, LTO3 in partition B) can one set of drives be SCSI and the
other Fibre?

Thanks!
