Restoring via XP Business Copy, while using mirror on primary site
situation we currently have is following:
Platform is Solaris 10 SPARC.
On production side we are using mirror within Veritas. Each half of mirror is on different XP24000 box, and while creating, expading, etc.. it's taken care that each half is based on enclosure.
We also use HP Business Copy on one storage to make a copy in time backup, which can also be made available on backup site.
To activate it on backup site it's done using 'vxdg -fC import <diskgroup>', and activationg volumes + mounting. Using -fC is required as disks were mounted on primary side, and when activating disk group, it cannot find other half of mirror (which is natural as there was mirror on production side, yet not on backup).
However, we have yet not tried proper recovery procedures in our scenario.
Has anyone some knowledge how we should make restore?
My main concern is this scenario: Primary site is working, we make a BC copy. However, after, for example, an upgrade is done, we need to revert to old copy.
We can resync backup to prouction - which means ONE half of copy is resynced from backup on primary site, but now is the tricky part:
If I just reactivate disk group, Veritas could see that 'production' one had newer timestamp than BC copy, and just resync mirror in that way that 'backup' we need to make as production is destroyed.
We need to be sure we can use backup copy, and make sure it will be primary copy when resyncing mirror.
I know it's a bit odd configuration, but this were business requirement we have.
If anyone has any ideas how to properly tackle this issues, would be most welcome :)
