Subject: Re: [Veritas-bu] FROZEN vs SUSPENDED
FYI -
We are running NB 5.0 MP3 and running Vaulting.
When we brought tapes
back onsite to test SQL DB restores (as we have nothing
else to do
ever), we found that Vaulting would remove the tape even if the
restore
was running during the scheduled Vault run. We also found that
NB would
append data to the tapes, which makes sense.
We changed the
status of the tapes to 'suspended' and that eliminated NB
trying to append
data but Vaulting still tried to send the tape offsite.
As of two weeks ago,
our largest SQL database took about 14 hours to
restore.
Luckily, I had
started the restore 18 hours prior to the next Vaulting
run or the restore
probably would have blown up. Experience has shown
that once the SQL restore
can't find a tape, the NB jobs just sit in the
Admin console and stay
green. What a life! Doing nothing but appearing
to be doing
something!
Update! I just checked the 5.0
NetBackup_AdminGuideI_WinServer.pdf
version (I despise PDF files for known
and unknown reasons. Here is one
reason why I hate them:
I wanted to copy
the text description in the manual to eliminate a
typing or other human
error. So, I just spent 10 minutes saving the PDF
to a Txt file then
opening the Txt file in Word and saving it as a Word
doc. I then searched the
Word doc for 'frozen'. It found on instance of
the word 'frozen' and of
course that wasn't the description of 'frozen'.
I also searched the Txt file
for upper and lower case 'frozen' and got
more hits but still not the
description. I know life is rougher for
others but crap!! I am just
trying to copy the text verbatim. No even
sure if verbatim applies to copying
and speaking or just speaking.
Technology! Blah!)
Here is the
description from the manual and yes, I should have just
typed the damn thing
in the first place:
(I am not responsible for errors or misinterpretation of
the following)
Frozen: The volume is unavailable for future
backups. A frozen volume
never expires, even after the retention period
ends for all backups on
the media. This means that the media ID is
never deleted from the
NetBackup media catalog and remains assigned to
NetBackup. (The BPMEDIA
command can also be used to manually freeze or
unfreeze (thaw?) volumes.
I added the (thaw?) to the previous
paragraph. So for next restore
test, I will freeze the volumes and see
if Vaulting still tries to move
the tapes offsite again.

SUSPENDED
We SUSPEND all tapes as they are ejected from the robot after
the
overnight backups.
That way, if we have to bring them back on site
for a restore, NetBackup
will not try to append further backups to
them. We had many cases where
a
tape was put back into the robot for
a restore (physically
write-locked);
NetBackup selected it for backup that
night if it was still in the robot
(in fact, seemed to favour those older
tapes). NetBackup did not like
trying to write to a write-locked
tape. As they were NDMP drives it did
not even seem to get a
sensible status back to say the medium was
write-locked, so DOWN'd the
drive.
Then it tries to load the same tape in another drive, DOWNs that
drive.
When it has DOWN'd all the drives, the backups all fail.
By
SUSPENDing the tapes, we no longer see this problem. When all
the
images have expired, the tape ceases to be SUSPENDed and can be
reused
with no special action.
FROZEN we will only use for e.g. tapes
subject to litigation - we would
also change the retention to 'infinite' so
the images don't expire and
so
don't have to be imported.
FROZEN happens mostly because NetBackup
decides it does not like the media -
it can easily set all the tapes in
a
robot to FROZEN if there is a problem
drive. So mostly we look for
FROZEN tapes, try and figure out how
it happened, and unfreeze them.

Hi
All,
Any opinions to the differences of a tape
in
FROZEN or SUSPENDED state?
Thanks in
advance ....
