RE: Tape libraries on IBM i hosting IBM i.

We do not assume that they will come up allocated UNPROTECTED. We double check by first using a cursor over qsys2.Media_Library_info to retrieve a list of media libraries and their status and handle accordingly. Also, for each entry verify that the resource is allocated unprotected.

Part of our startup.

They are coming up allocated unprotected then.

If you add a new device you’ll have to allocate it.

Well, not quite.

What you do is allocate unprotected. That way any of the partitions
can grab a tape device as needed, then release it when it's done. To
set a tape device so it is exclusive to a partition you would allocate
it protected.

So, you must allocate them to start with.

Jim,

We have FC cards on each LPAR connected with a FC switch to the tape
library.
All drives in library available to either LPAR, with the correct zoning.
No need to allocate/deallocate.

IF you have the attachment cards, (with a SAN switch) then you can
just allocate/deallocate, no real need for VIOS.

I agree VIOS is the better choice, but it can be done without.

For i on i there is not much option. Best idea would be to have a VIOS
and NPIV config.

Then again, a VTL all but solves the problem since they can emulate
multiple libraries on a single device. All that holds that up is the
attachment card on the POWER system.
