Error accessing 7212 tape library within TSM

Hi,

I have a small TSM server using a 7212-312 vxa tape library.  The
library has one tape drive and 10 slots.  I am currently getting the
following errors trying to communicate with the tape library and can not
for the life of me figure out the problem.  I currently have a PMR open
with hardware support, and a PRM with TSM.  Hardware is saying it's a
TSM problem, TSM support is saying it's a hardware problem.  I haven't
been able to do backups for a week.  Any guidance is appreciated.
I've opened a PMR with IBM.  The CE came out and said the hardware is
fine, but TSM cannot communicate with it.  TSM support says we needed to
upgrade to TSM 5.2.6.3.  We were at TSM 5.2.4.5.
