I've searched the mailing list and veritas knowledge base, found a couple
of people asking the same question but no answers :(

# bpexpdate -deassignempty
Search for empty media that meet the following criteria:
        Host: All
        Media id: All

Continue? y/n (n)y
Could not update media list, host is unreachable
host is unreachable

bpexpdate -deassignempty runs automatically every so often, but recently
it's been failing with the above error and I've got no idea why!
bpexpdate -d ... -ev ... etc works.

Has anyone got any ideas or tests I can run?

Many thanks, Justin
