In case its not obvious, I know virtually nothing about Hyper-v.
But having recently bought 2012 Datacenter, I thought I should really give it a go.
I have an HP DL385
and an HP 1/8 G2 LTO-5 Ultrium 3000 SAS Tape Autoloader
Is it possible to connect and use the SAS tape auto loader to a Virtual Server running on Hyper-v
