Flashcopy and AIX raw Lvs..interesting solution??

[polani]

Guys

I have a requirement of reducing oracle offline backup time from 6 hours to few minutes and for this i am planning to use IBM Flashcopy option on DS4800!!

Currently two AIX 5.2 nodes running Oracle RAC with raw lvs configuration. Solution will include another new node with AIX 5.3 , as a backup node only.

We will stop Oracle RAC as normal for backups, take flash copy and mount target flashcopy drive on new backup server.Later on Rman configured on backup server will take backup normally to tape cartridges?

Do you think any hidden technically issues in this solution?

Anybody really using flashcopy with raw lvs ?

I have to forcefully varyonvg of flashcopied drive on backup server ( using varyonvg -f or -b etc ).

As backup solution is veritas , so i will ask question for out veritas guys as well that whether veritas client can take backup from raw lvs ( in case we dont use rman for offline backups only ).

Any suggestions/comments from AIX,storage/veritas guys are wellcome

Thanks

for whatever its worth, it sounds like a good solution to me. I'm not a big netbackup guy but we do have it in our environment and i'd suggest using rman to do the backup.

otherwise netbackup will backup the entire lv, it has no way of performing an incremental with raw devs.

Hi

I am still waiting for any more valuable comments... It seems that nobody is using Flashcopy with RAW logical volumes ?

Is it right? Or there are people who are using RAW logical volumes being backed up with help of flashcopy?
