EMC Unity RE-IP
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.
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.
