A customer of ours recently upgraded from esxi to vsphere 4. After the upgrade we have been unable to see the tape drive attached to thte server.
The drive is an HP Ultrium 448 LTO plugged in to an adaptec ultra320 29320LPE.
The correct card appears in the vshpere client under configuration/storage adapters but I do not see any deivces plugged in to this card.
If I click on "path" on the adaptec card I see the status is appearing as "dead"
Any idea why this was working fine in esxi but is now not working in vsphere 4?
