EMC Unity RE-IP

Question

Hello there, I currently have a working pair of Unity300 in 2 sites with file replication from Site1 to Site2. I will need to RE-IP all interfaces on the Unity in Site2 as part of a datacenter networking project. I have to change the MGMT IP on the Unity, and change the Replication Interfaces in Site2 and get the replication working again between the sites. I am looking for a process/procedure to handle this RE-IP requirement so that I won't have to lose any data that is already SYNC there at Site2, I don't want to have to start replication from scratch. Any pointers would be helpful. Thanks.

Have you done this?

I have only done this on a pair of Unity VSA in our lab, not yet in production.

Build vsa-1/prod and vsa-2/recovery with all NIC on the same portgroup/VLAN, then change vsa-2/recovery.

This seemed to work to emulate/simulate networking changes.

PROD/RECOVRY	setup all NICS for both VSA on VLAN60
PROD	PAUSE the replication NAS
PROD	PAUSE the replication FS
RECOVERY	shutdown "RECOVERY" storage system
RECOVERY	VMware (change the nics) on VSA-2 to VLAN50
RECOVERY	change the IP of "RECOVERY" unity (cmdline on console in VMware)
RECOVERY	login to unisphere in RECOVERY
RECOVERY	change replication interface
PROD	Edit the replication connection
PROD	verify and update replication connection
RECOVERY	edit NAS server interface on RECOVERY site/override
PROD	resume NAS Server
PROD	resume FS
PROD	sync the FS
PROD	verify the current NAS Server settings in DNS/auto-AD
PROD	Failover NAS Server between "PROD" and "RECOVERY"
PROD	Failover FS between "PROD" and "RECOVERY"

Then, fail back to PROD, verify, etc.
