We're in the process of moving to new datacenters. All servers will be moved over but the SAN won't. The SAN will be replicated to a new SAN in the new datacenters by our SAN admins. That means, the LUNs in the new SAN will be identical to the old, also the LUN numbers.
Example output from 'vxdisk list' on the current host shows:
c1t50050768014052E2d129s2 auto:cdsdisk somedisk01 somedg online
This disk will get same LUN nr, but the target name will probably differ as it's new hardware in the new DC.
Will this work with Veritas SFHA? If not, is there any way to do this the way the datacenter project wants to?
If I could choose to do this my way, I would present the LUNs on the new SAN to my servers so that I could do a normal host based migration. Add the new LUN to the diskgroup and mirror the data, then remove the old LUN. However, I'm told that the hosts in the current datacenter won't be able to see the new SAN.
