As we - and StorageTek - recently learned, VMS will not provide support
for Generation-1 LTO due to blocksize limitation issues and others.
Gen-2 LTO is not here yet, neither is VMS support for it. So, SDLT is it
for now.

That said, we are likewise having SDLT issues. The drives are Quantum,
not HP-badged. Also, they under contract with StorageTek thru the VAR
and not with HP. So, essentially, we have no support for our SDLT drives
on VMS since neither StorageTek nor the VAR has OpenVMS support
resources. Messages like "Extended Sense Data received" mean nothing to
non-VMS folks, apparently.
