Thanks - very good info to chew on here.
I know if I used the RW ssid/cloneid, it did the cloning session from
the RW device, which is not ideal since it would block other backups.
However, if I need to use the RO ssid/cloneid to do the staging, I'll
have to save the RW ids as well, and as you say use nsrmm instead of
nsrstage it seems.
I was not aware of nsrstage having issues if there is a write session.
That kind of blows the reason for doing the clone off the RO volume.
By the way, this is on 7.4.1

As you have discovered nsrmm -d -S {ssid} deletes all the clones... Not

Nsrmm -d -S {ssid/cloneid} works fine, but the trick here is that
there are two cloneids for the aftd version - the RW device, and the RO
device... The big secret here is to delete just the RW cloneid, not the
RO one... When the process is finished deleting all the savesets you
follow it up either by running 'nsrstage -C -V {volume}' or ' nsrmm -X
-V {volume}.RO' to reclaim the diskspace.
There is a difference between using nsrstage -C and nsrim -x...
Nsrstage does not work if theres an active write session on that volume,
but on the other hand it can work when the volume has had all of it's
savesets deleted. Nsrim -X works even when there's writing
happening, but does nothing if you've just removed the last saveset...
Neither can reclaim space while a read is happening however...
It may seem tempting to try deleting both the aftd cloneids - it will
let you, but then you will never get your disk space back unless you
relabel the volume...
This all relates to versions up to 7.2.2. so far 7.3.3 appears to
have the same behaviour, although I'm hoping they've fixed the
reclaiming of disk space while cloning...
A big caveat here! Just because you have copies>2 does not mean
they're all GOOD copies.. You should take care not to delete the disk
copy until you are sure the tape based ones are complete - i check
clflags is blank on the tape clone before deleting.

Hello Brian,
I believe you are speaking of "nsrstage" instead of "nsrclone".
Actually I meant "nsrstage" instead of "nsrmigrate" - the
latter was one
of my script names... :)
I actually DID do as you suggest, as I said - I used
ssid/cloneid pairs
for my list. When I had issues with that (not the same
issues) I tried
ssid only. I tried switching back, and it didn't work - but I
may just
have found an "OOPS" in my code from when I tried something,
and I may
have generated a list with both just the ssids AND the
ssid/cloneid pairs.
I'll know tomorrow when I've got something to migrate... :)
