tape drives go offline

[IanT]

Guys,

Got a 1u rack HP Storageworks......with 2 SAS Tapes drive in............for the past month one of the drives was going "Offline"...........we have to power the enclosure down and back on and all works.......now I've swapped the entire enclosure over as we had a spare and doing the same.........any stuggustions

the 2 tape drives run into a single SAS Card in the enclosure and psu has been changed

It could well be the SAS card playing up, seeing as you have swapped everything else.
