I have had a tape drive running on my Z400 Workstation for about a year now with no problems.
The drive is the HP LTO-6 Ultrium 6250 (external).
Recently the drive stopped reading tapes. It mechanically loads them in, but then the HP Tape Cartridge Utilities in the LTFS Configurator won't load the tape, and Windows kicks up an error box saying "Drive reported Unit Attention. Please try again."
I've been speaking with HPE who have run some diagnostics and even swapped out the drive, and still the same problem.
They said to come on here and ask for some help, as the Z400 isn't on their support list.
Even though it has been working up to now, they say I could try and change my HBA card as it's not an approved one.
I'm currently using an ATTO ExpressSAS H644 in a PCIe2 slot (only PCIe slot I can use).
Does anyone have any suggestions for the error in general, or can suggest a PCIe2 SAS card that is approved for the Z400.
Thanks, Stuart
