As i type this I'm thinking this is not possible but let me try.

Can you have multiple tape libraries into a single port? Gut says yes,
brain says no.

I have one tape library, with multiple drives, shared by multiple lpars of
IBM i, across two power 8's. VIOS lpar on one rack hosts it to all of
it's lpars of IBM i and has the physical fiber tape card. Similar
situation for the other rack.
Both connect to a SAN switch that supports all four drives.

Here's the catch, the fibers do not connect to the library, they connect
to each of the drives but they still show up as
WRKMLBSTS
Device/
Resource Status
TAPGRT01 ACTIVE
TAP01 OPERATIONAL
TAP02 OPERATIONAL
TAP04 OPERATIONAL
TAP03 ACTIVE

So, if I tried to control multiple libraries from one fiber port,
and you connect directly to the drives,
how would it know to put the drives on the other library on to a different
library?
