Re: SAV of virtual optical - when ALWSAV changes -- MIDRANGE-L

We are doing that tonight - setting the catalog entries ALWSAV *Yes after
unload, SAV, and then verifying DSPTAP SAVRST.
After SAV, Load should set to no, and then next night the unload "should"
set to Yes without our intervention.
We don't have an easy way to determine when this happened - pull tapes and
for each a 2 hour DSPTAP *SAVRST...

Can you confirm that when unloaded the images DO say ALWSAVE(*YES)? It
certainly also allowable to flag them as *NO and then it 'sticks' even when
you unload them. I do this routinely with PTF images as I don't want to
affect my customer's backups should the images be there through a backup.

That's the issue for sure. Any catalog that is loaded in a virtual device

is flagged ALWSAV(*NO).

ONE reason why this is true is so the save will actually finish. If it
allowed you to save them while loaded and you were backing up TO that
virtual optical device is could in theory be making the object being
saved
larger or more numerous (or both) OR you'd run into locking issues and
get
only part of it anyway.

So you're doing the right thing by unloading them if you want them backed
up.

I did a DSPTAP *SAVRST to print of a SAV of /EKDVIRTUAL (our

directory of virtual optical) and subtree=*ALL. This is not ptfs or
software, but real images. We are using the IBM PRPQ to handle
library mode=Yes on these.

We see the primary and second directory in the *SAVRST, but not the
catalog entries.
Checked and have ALWSAV attribute set to *NO - but we don't know how
they changed from *Yes to *NO.

Likely Load Image Catalog (LODIMGCLG); see below.

When we test the unload, the attribute changes from *NO to *YES, and

we do an unload just before SAV.

Do not have BRMS. V7R1

"...
_Performing a save operations_

To save files to virtual optical storage, see Consider using
virtual optical storage in the Back up your system topic.

Note: When the image catalog is in ready status, all images in the
catalog have a *ALWSAV attribute value of *NO. This does not allow the
images to be saved by the Save Object (SAV) command or the QsrSave API.
When the image catalog is not in ready status, all images in the catalog
have a *ALWSAV attribute value of *YES. This allows the images to be
saved.

3. If you want to exclude virtual images from a full-system save, use
one of the following strategies. Virtual images can significantly
increase the time it takes to complete an Option 21 save operation, even
if the image catalog entries do not contain data:

• Use the Change Attribute (CHGATR) command to mark the image
catalog directory as nonsavable. For example:

CHGATR OBJ('/MYINFO') ATR(*ALWSAV) VALUE(*NO)

• Use the Load Image Catalog (LODIMGCLG) command to make the image
catalog ready. Image catalogs with a ready status are omitted from the
save operation.
• In an attended save, you can specify to omit the image catalog
directories on the Save Object (SAV) command.
..."

This trying to figure out what in IFS has ALWSAV = NO or YES (I

don't see anything on SAV that tracks this for verification). What
are others doing to be sure your backing up what you think your
backing up?

There should be the msg CPD3775 as an indication after-the-fact; I

made several comments in the following thread [in English]:
