Hopefully, this does not post several time...if it does apologies in advance.
(My email address changed.)
Assuming you have the TS1130's in a 3584: you can create virtual libraries and
assign slots and drives to each library. We did this to avoid having a single
point of failure in the TSM library manager and also not have any contention
for resources on the library, except the accessor. However, the "shared"
accessor has not been an issue for approximately 500 mounts per day. Doing
this keeps everything nice and neat for your TSM servers. Just my 2 cents
worth.
BTW, I am curious: how much are you backing up nightly? What is the
configuration of the library?
Regards,
Mahesh

Hi,
this can work (I admit I haven't tried it with TS1130) - ESX4.0 supports FC
tape drives (new feature - was not working with 3.5) and you can dedicate whole
FC HBA to the virtual machine.
But even if it works it remains unsupported.

I believe that the ts1130 is fc only, no scsi or sas, vmware doesn't support
access to fc drives from a guest, last time I heard. So there it stops.
If you'd have scsi or sas tape devices, you could get them to work from within
a vmware guest, no problem. Support might be an issue, if I read the docs right.
