KZPBA-CB replace KZPSA-BB with TruCluster 1.5 & DU V4.0D

This summary is VERY late in coming because we have just now had time
to try this again. We were able to come in this past Saturday & got
the KZPBA-CB UltraSCSI adapters to work.

We had received a number of suggestions from the list, but all had
already been tried & verified. We finally discovered the problem on
our own.

What we found is a descrepancy in documentation on the setting of the
switches in the DS-BA35X-DA personality modules in the DS-BA356
UltraSCSI shelves.

The "TruCluster 1.5 Hardware Configuration" manual states:

"Ensure that the personality module (DS-BA56X-DA) switch pack 4
switches S4-1 and S4-2 are off."

The "TruCluster Software Products Hardware Configuration Technical
Update for KZPBA-CB" document states:

"Ensure that the personality module (DS-BA35X-DA) SCSI bus
termination switches (switch pack 4) S4-1 and S4-2 are set to ON."

These switches had been set to OFF as per the "Hardware
Configuration" manual. Once we set them to ON every thing worked
perfectly.

Below is the original question.

======================================================================

We currently have a cluster running DU V4.0D & TruCluster 1.5 on AS
4100s with DS-BA356 UtlraSCSI pedistal shelves containing DS-RZS2DF-
VW UltraSCSI disks. When we built this configuration last year we
had to use KZPSA-BB SCSI adapters because KZPBA-CB UltraSCSI adapters
were
not supported in a TruCluster ASE environment.

The KZPBA-CB UltraSCSI adapters are now supported with TruCluster
with the following requirements:



1. Patch Kit 3 must be installed

2. KZPBA-CB requires ISP 1020/1040 firmware Version 5.57, available
with the system SRM console firmware on the Alpha Systems Firmware
5.3 CD.

We wanted to replace the KZPSA-BB SCSI adapters in one machine with
KZPBA-CB UltraSCSI adapters to get faster I/O. The 2nd machine is a
backup machine only & we were not concerned about replacing the SCSI
adapters in this machine at this time.

We came in Saturday & installed Patch Kit 3, replaced the SCSI
adapters & upgraded the firmware from the 5.3 CD.

Now the problem.

We entered "show fru" to ensure that the machine saw the new
UltraSCSI adapters & everything looked fine.

We entered "show device" to verify that the disks were all there.
The display showed the new UltraSCSI adapter, but was unable to show
the
disks. The display would just hang at this point.

At this point we even brought down the 2nd machine & power cycled
both machines & the shelves to ensure that everything was reset with
the
same result.

We finally put the old SCSI adapters back in & returned to normal
operation.

Has anyone out there had any experience with this sort of thing?
