If ur using option Scratch it is working and your Initializing problem could be solved but i have doubt that this TAPE will work fine at the time of Restoring if it will require....?
Thanks

Hi,
Can you tell us one thing, how many tape lables you are maintaining in your profile?
If you are maintaining 6 lables with expiration period of 6 days, there is no need for re-initialization.
Check the same and let us know....

Hi Nick,
there are six tape levels only as given below -
volume_archive = (PRDA01, PRDA02, PRDA03, PRDA04, PRDA05,
PRDA06)
volumes for brbackup
[<volume_name> | (<volume_name_list>) | SCRATCH]
no default
volume_backup = (PRDB01, PRDB02, PRDB03, PRDB04, PRDB05,
PRDB06)
expiration period for backup volumes in days
default: 30
expir_period = 6
recommended usages of backup volumes
default: 100
tape_use_count = 100

Hello Manish,
if I correctly understand what you are doing, expir_period = 6 should be ok.
A tape will be released for further use after 6 days, and from one Monday to the next there are more than 6 days.
So I think you should tell us your exact error message, to avoid possible misunderstandings.
What do you mean by tape vol name error ?
Did you use all your 6 tapes in the meantime?
regards
Hi Joe,
I can take backup on new tapes after initializing from Monday to saturday without any problem.
Now on Monday whn I try for backup again on tape laveled as Monday it givs "wrong vol found.......expected vol lavel is ..........."
SO i have to reinitialez again and the bckup completes without any problem.
So main things is tht I have to re-initialize everyt tape for reuse.
Regards
Manish
Somehow I expected that.
And what about:
Did you use all your 6 tapes in the meantime?
For example, if you leave away Saturday's backup for whatever reason, and only use tapes PRDB01, PRDB02, PRDB03, PRDB04, PRDB05, then on next Monday, brbackup will insist on PRDB06.
That's the way it works.
And by the way, you didn't give us the exact error message.
wrong vol found.......expected vol lavel is ..........."
That many dots ? really?
regards
Hi Joe ,
For example, if you leave away Saturday's backup for whatever reason, and only use tapes PRDB01, PRDB02, PRDB03, PRDB04, PRDB05, then on next Monday, brbackup will insist on PRDB06.
I this could be the reason -
Well the error is -
BR0216E Wrong volume PRDB05 found in device /dev/nmt0, expected: PRDB01
I hope I can solve my problem and will let you know
Regards
Manish
I suggest you insert the needed tape, i.e. PRDB01.
Always insert tapes PRDB01, PRDB02, PRDB03, PRDB04, PRDB05, PRDB06 in exactly this order, then start from PRDB01 again.
And do not rely on each tape being for one fixed day of the week.
Your life will be easier if you follow SAP's way of doing things instead insisting on your own way.
regards
Hi Joe,
When I initialize tapes, it says ---
BR0207I Volume in device: /dev/nmt0 will be initialized with name: SCRATCH
now after tht after takign backup it says -
BR0103I Following backup volume will be used: PRDB01
My question is, while initialization it is using vol name as SCRATCH and while taking backup it is assigning vol name as PRDB01 ?????
why it is so ???
does tht mean next tape will be used as PRDB01,02,03,04,05,06 ????

Hi...
What command you are using to initailize tape.?
For taking Redo log backup, I would suggest to have redolog for 2 week, if you taking backup every week. It will add redundency so reliability in your backup.
So if you want to have it for 2 weeks you can have 14 tapes for 1 day each. Initailize all of them using command line and have in your backup repositary.
To initialize tape, Try command..
brarchive -i force -v <volume_name>
e.g. brarchive -i force -v PRDA01
Hope fully it will not warn for SCRATCH and also solve your problem.

Hi..
When you use DB13, The Volume is initialized by following command.
brbackup -u / -i force -c force -n 1 -v SCRATCH
-v option is for specifing volume. By default it is initailized using name SCRATCH and used in very new tapes.
When you take backup of redolog or database backup using DB13, it again initailize the tape with volume name specified by you if it is SCRATCH (i.e. DB13 initialized) otherwise it will show Error for wrong volume. ( as in your case it is showing after a week).
I would suggest to initailize volume using command line utility and not to stick DB13 Tcode for initialization. Login with user <SID>adm and initialize volume as i mentioned earlier. ( check my last post in thred).
By doing so, All volume will be initialized by their name. And there is no dought that backup taken in these tapes are 100% safe, sure and reliable.
Hope it will solve your all problems,
Regards,
Abhimanyu.
set expire_period to 8
(this means 8 days)
