[ale] LVM BCV anybody?

[Lightner, Jeff]

The thread about the USB made me decide to ask:

Is anyone doing BCV setup with LVM wherein they use a disk array (e.g. EMC or Hitachi) to synchronize (essentially mirror) data disks on the array itself then split the newly synchronized devices so the mirror can be mounted on a different host?

I’ve done this for years on HP-UX and Solaris and will soon need to do something similar on Linux (RHEL5).   I’m wonder if others are doing it and if so if they’d be willing to share the key steps.

Note I’m not asking how to do the synch and split on array but only the steps to make a Linux LVM system use then later release the split disks.   (The later release would be to allow for the resynchronization.)

Current process is something like:

1)       Production disks are mounted and running an Oracle DB from disk array.

2)      Synchronization is done on the disk array to copy those disks to another set of disks.

3)      Once synchronizatrion is complete the Oracle DB is put in hot backup mode.

4)      The copies are split from the original production disks so that they are no longer synrchronizing.

5)      On a separate host the disks are seen via the SAN and imported/mounted looking like they had on the original server.

6)      We do a backup from this copy.
Note that the copies are never actually seen by the original server even during the period they are being synchronized.   That process is wholly within the disk array.
