All said the same thing. This was a bug that was found on the 8x00 class
servers with PK5. It had nothing to do with the firmware level (one had the
problem with FW 5.4), or the KFTIA module. This was a problem with the
patch kit itself, which is fixed by replacing the isp.mod file. This will
be included in PK6 when released.

Original Question:
> 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

> 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
