Yes, with a Qualstar TLS-4210 with two AIT-2 drives. The errors went away
after a firmware upgrade of the drives (revision 0107 --> 010f, according
to the service protocol).  Since then, no problems.

The firmware revision is now 0204.

Any tool that executes a SCSI inquiry command should do. I'm sure there is 
something on AIX :-)
