If you are using SWCC, there is a "save configuration" menu item. If you
are not, I would print out the output from show units, show storagesets all,
show disks, sho this full, and shoo other full.
In theory (no guarantees), restoring the configuration (from either) should
work so long as you don't make changes to the logical disk structure in the
interim.

Hello Eyal:
1: when you initialize a raid or stripe or mirror you muast do:
init raid 0 save , and all the coniguration is save. It isn't necessary to
use the save in all the inits, only in one or two of them.
2: when you change the controller, it looks for a save configuration, and
you don't loss any data.
Good luck!

I believe there are three methods.
1. If you have access to hszterm simply do the following
commands and save them to a file:
"show this full"
"show other full" if you have redundant controllers
"show device full"
"show storage full"
"show unit full"
Restoring them is simply a matter of taking a bare controller and
typing the appropriate commands.
2. SWCC may offer some option to save and restore a
configuration. Read the SWCC documentation to find out.
3. Recent versions of controller firmware offer a feature to
have the controller save a configuration record to specificially initialize
disks and storage sets. The feature is enabled through the use of the
INITIALIZE command with the SAVE_CONFIGURATION option. Unfortunately, this
means have to initialize a unit. If you initialize an existing unit IT WILL
OVERWRITE YOUR DATA.
The method of restoring a configuration depends on the method used
to save it. In the case of saving the configuration to a file, you simply
go back and recreate all the storage sets and units by hand. The program
CONFIG will recreate the bare devices for you. None of the ADD commands
will overwrite the data on a device. The controller knows the original
order of Storageset members, so you don't have to worry about the order when
recreating them. As long as you DO NOT initialize a device or storageset,
there shouldn't be any problem.
If SWCC has a method of saving, it also probably has a method of
restoring.
There is a complementary command to INITIALIZE with SAVE_CONFIG that
restores a saved configuration. I don't recall what it is, but it should be
documented in the CLI reference manual if the particular version supports
SAVE_CONFIG.
In a configuration with redundant controllers, both controllers keep
the configuration. As long as you have one of the two you can replace a
controller and synchronize the new one with the old one by using SET
FAILOVER COPY=... Make sure to use the remaining controller as the source
for the copy.
If disk where you save hszterm output copies of the configuration is
on the HSZ, print copies of them as well. Those disks won't be available if
both controllers are being replaced.
