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.

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.
