Greetings everyone,
We had some wierdness happen with our tape backup system on an 8200 running
DU 4.0D PK5 and Firmware 5.5 on the first backup after our upgrade. We had
3 tape drives out of 5 error due to bus resets on the SCSI busses that they
were attached to. Each drive (all TZ89's) is on its own controller for
maximum throughput. Two of the drives are on controllers inside a KFTIA
module, and the third is on a KZPSA which is linked via a KFTHA hose. We
logged a call with support, and engineering released a patch that modified
our "isp.mod" file, which seems to have fixed the problem. They have seen
this problem with people who are running PK5 and/or FW 5.5 on systems with
multiple controllers.
We are somewhat wary of the answer that we got from Compaq Support for this.
We also have an 8400 running the same OS/FW revisions with 5 TZ89's attached
without any problems. The difference between the two is that we do not have
a KFTIA on the 8400. All 5 tape drives are running off of KZPSA's linked to
a KFTHA module. I know that the SCSI busses on a KFTIA show up as "isp#"
devices on the system, which is also fueling our suspicions.
Since KFTIA's are obsolete hardware now, could there be a problem where the
firmware is not supported anymore and the FW5.5 CD screwed things up? Could
it be the patch instead? Or was Compaq Support exactly right and we just
tripped on a bug in the PK?
Our minds would rest easier with any sort of hint. :)
Thanks in advance,
