If you change the PVID on the BCV, I doubt the disks will import in any
way.
This procedure is exactly what I do every night.
We do a split, and importvg, a "DB2 instance update" and both a DB2 backup
to disk and a "Sysback" of the entire VG.

| Subject: BCV/EMC backups on AIX |
>-------------------------------------------------------------------------------------------------------------------------------|
We have some AIX machines attached to EMC on which the
storage admins want to do a BCV-style backup. After
this the new disks will be mounted and the cold
database backup performed from these disks.
I guess this is functionally equivalent to a split
mirror backup, except that the ENTIRE disk is copied
(VGDA and PVID also). This makes it such that we have
to them remount the disks onto another system (so as
to avoid conflicts) and perform the backup from there.
Am I on the right track?
Any way I can avoid having to move the other disks to
another system? Will the recreatevg command help me
here to recreate the volume group if I were to
manually change the PVID of the BCV'd disks?
Thanks.
