The problem might be the media.  If you use a brand new tape after cleaning
do you get the same error.   Other possibility may firmware (hp02 and hp03
have seen a problem) or yes hardware

problem
DDS3 tape drives log powerfail events when connected to A6829A cards.

Temporary Solution

TEXT
workaround
Try A5149A/R and A5150A/R add-on HBAs

Or, simply move DDS3 to System Core I/O SCSI Bus (free):

A-Class path 0/0/2/0 or 0/0/1/0
N-Class path 0/0/1/0
