I backup EMC BCV's now. You question is a bit broad but I'll give you my
quick-and-dirty information and then you can decide if you want more.
Currently, I have a ~300M database that is on an EMC 3830. Each standard
mirror for the data disks has an associated BCV. These BCV's are not
visible (via port mapping) to the same host that can "see" the Standards.
In other words, when my BCV's a split, those luns are not visible to my
database box. They are visible, however, to my backup server. Once I split
the BCV's, I then import the disk group to by backup box, start the volumes,
fsck, & mount the filesystems. I then just do an ordinary file backup to
tape.
The fine detail order looks like this:
To start the backup process (part of a bpstart_notify process):
1. Backup Oracle Controlfile to trace
2. Place Oracle tablespaces in Hotbackup mode
3. Split BCV's for data volumes only.
4. End Hotbackup mode for tablespaces
5. Split BCV's associated with Oracle archived redo
6. vxdctl enable on backup server (unnecessary on some
servers - I think it's scsi chipset on controller)
7. import (with "Clear") the disk groups for data and
archived redo (vxdg -C import <dgname>) on backup
server. The volumes, plexes, & subdisk config
comes along for the ride on the import.
8. recover the volumes (vxrecover -g <dgname> -sv
9. start the volumens (vxvol -g <dgname> startall
10. fsck the volumes
11. mount them locally on the backup box for simple file
backup to tape.
To reverse this after backup (bpend_notify):
1. unmount the filesystems
2. stop the volumes ( vxvol -g <dgname> stopall )
3. deport the disk groups ( vxdg deport <dgname> )
4. Establish the BCV's
Let me know if you want more

Subject: [Veritas-bu] Backing up EMC BCV
Can anyone give me advise on backing up EMC BCVs?
I have a requirement to setup a NBU environment to do the above, probably
using NBU 4.5
Thanks,
