Hi,
Due to popular demand, here is the official word, via Mark Silverberg
of HP:
The HSZ70 product set is supported on Tru64 UNIX V5.1B. Below is the
support statement found in the 27-June-2003 V5.1B Technical Update
Document located on the external HP Tru64 UNIX Documentation Website:
http://h30097.www3.hp.com/docs/updates/V51B/TITLE.HTM
Technical Update for Tru64 UNIX Version 5.1B June 2003
New and Changed Features
May 19, 2003: HSZ70 Storage Array Controller is Supported on Tru64 UNIX
Version 5.1B
Section 2.3.1.2 of the Tru64 UNIX Version 5.1B Release Notes incorrectly
announced the retirement of the HSZ70 storage array controller in
conjunction with the release of Version 5.1B of the Tru64 UNIX operating
system.
The HSZ70 is supported with Version 5.1B. The controller driver software
is included on the kit, and the Version 5.1B documentation includes
troubleshooting information for the HSZ70.

Hi,
I just came out of a meeting with HP. Due to popular response, the
HSZ70 is officially and publicly supported under T64 5.1B. It is
expected to be desupported down the road, but I have no time-line for
when desupport might happen. --Joe

Subject: SUMMARY: Upgrade from HSZ70 to HSZ80
Thanks to Dr. Thomas Blinn, Toni Harbaugh-Blackford, Alan Rollow and
Bruce D. Hines for the speedy reply.
>From Bruce Hines:

Steps to swap HSZ70 to HSZ80
1. Backup all data on HSZ70
2. Capture all HSZ70 configuration information:
a. show this_controller full
b. show disks
c. show storagesets full
d. show devices full
3. Shutdown host and HSZ70
4. HP does their thing
5. run config (to add all devices it finds, like DISK10000, etc) 6. add
mirrors, add stripes, add spares (DO NOT INITIALIZE ANYTHING) 7. add
units (I would use same names for all containers and units) 8. boot host
I would detail out the steps with each container name with commands
(makes it easier to cut-n-paste when you get ready to do it) then run
your plan by HP for proof of concept.

Steps 1. and 2. are already done as part of our disaster recovery
procedures and the rest isn't all that painful. If push comes to shove,
that will be the way that we go. However, hope comes from Dr. Thomas
Blinn:
---
What you propose SHOULD work. However, you should also ask when there
might be HSZ70 support under V5.1B. My understanding is that we have
committed to provide such support precisely because of situations like
yours, so unless you really WANT to upgrade, you might be able to not do
so (assuming all the testing proves out OK -- my understanding from the
status reports I've seen is things are looking good so far..).
---
We are scheduled to meet with HP next week so maybe they will have
more information for us. It would be great to not have to upgrade.
