Re: ATR(*ALWSAV) Was: Migrating extant system to new hardware

That's a good idea; it depends on how time critical the migration is - plus
I usually prefer to keep them simpler.

Testing the BRMS recovery is certainly good practise.

I paid homage to that in a recent thread. However I just like to do it
with BRMS. Gives me familiarity with, and tests, their recovery process.

THose are pretty much the same ones I set - image catalogs and storage
spaces and more or less the same reasons. I can recreate the image
catalogs
easily enough and the guests need a specific save strategy.

But I also have clients that keep thousands of XML files and use virtual
tape (well technically I guess that is an image catalog) and I exclude
those too.

I use BRMS for most saves but for migrations I much prefer to use the GO
SAVE option 21 save.

In general I do not set
CHGATR OBJ('/mydir') ATR(*ALWSAV) VALUE(*NO)
Instead I set this in BRMS, using omits, for directories I wish to omit
during backups. And then in BRMS, if I want to save them, I simply add
the OMITS(*IGNORE) parameter to STRBKUBRM.

The two exceptions are:
- the directories containing image catalog entries (and even then I've
been know to change them for an unload/reload)
- QFPNWSSTG on my hosting lpars. I prefer to save the guests instead.
And
do not see the need to double save. In case of disaster I will rebuild
the storage spaces, and perhaps balance them out better. I have changed
this when doing a data center migration when I saved only the hosting
lpar.

IBM, starting with 7.2 I believe, has changed a whole bunch of
directories
with ATR(*ALWSAV) VALUE(*NO). Mainly certain logging directories. You
will see a bunch of these messages in your saves:
CPD37C3
Message . . . . : Cannot save /tmp.
Cause . . . . . : The ALWSAV attribute on /tmp was set to *NO
preventing
the object from being saved.

You will potentially get bitten on this if you have anything marked as
ALWSAV(*NO) as well.

I have a few directories I mark as ALWSAV(*NO) but I generally review
this
before an unload/reload so I know what I have to recreate.

This is a BRMS term.
Basically the cure, when you know you are doing an unload/reload (or a
full system save where you want most everything) is when you use the
BRMS
command STRBKUBRM you do not forget to change this from the default:
OMITS(*PROCESS) to OMITS(*IGNORE)
We always do the *IGNORE on our quarterly saves.
