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 I found a known problem 8606308158 Problem Text CR# JAGae71193 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 Best Regards Cathlene Mc Rae HP Sr response center engineer. * To join/leave the list, search archives, change list settings, * * etc., please visit http://raven.utc.edu/archives/hp3000-l.html *
