Hello,

We are on IBM AIX 4.3.3 with EMC and BCVs. Our Unix admin has setup the backups for the database in following sequence to do the Hot backup.

1. Put all tablespaces in the database in Hot backup mode
2. Sleep 5
3. Put all the tablespaces back into normal mode
4. Split the BCV's
5. Mount on another machine and backed up from it.

What I am concerned is with step 4. Split BCV's should be done at step 2 instead of step 4.
According to our Unix Admin, EMC takes care of consistency and there is no need for any concern. As per him the split is instant split and EMC guarantees consistency.

What do you all think. What is the recommended procedure.

TIA, Nate
