We use EMC SAN disks with 100 miles between data centers. We let the SAN
folks do live replication between the data centers on the SAN LUN. It is
mounted as /openv on the master servers.
Two separate master servers, two separate locations, two separate SAN disk
arrays mirrored over a long fiber.
If either site goes down, the other site mounts a freshly broken SAN LUN to
an alternate file system mount point (something like /openv_other_site).
Copy the images from DR backups, load tapes from DR off site location, add
force_restore entries in bp.conf and you can start restoring.
Works and have tested DR restores.

Subject: [Veritas-bu] Question in regards to high availability of the
catalog.
Has anyone performed a high availability catalog across different
datacenters?
For instance:
Master [Datacenter1] --------------> Netapp [Datacenter 1]
^^^
|||||
vvv Master [Datacenter2
(standby)] -> Netapp [Datacenter 2]
Where the two netapps are synced via their own protocol for replication?
Has anyone done this or similar methods of catalog replication across
multiple sites?
Thanks,
Justin.
