I've such problem: I need to replicate lun1 from eva1 to lun2, eva2. Next I will break the connection between the evas. So here is the problem - how to present lun2 to the same host, so that it "sees" the lun2 as the lun1.
Assume that I will unpresent the lun1. The host is windows.
Thank you.
Solved! Go to Solution.

Re: Replication to 2-nd EVA and presenting to the same host
1) Controlled failover: Destination disk becomes source and is accesible. Source disk becomes destination and read-only or inaccessible.
2) Delete DR group, leaving destination vdisk. You'll have two independent copies of the vdisk, at the moment the DR group was deleted. Then you can unpresent one and present the other.
Obviously the server needs SAN access to both EVAs, so you cannot break the inter-site link.

Re: Replication to 2-nd EVA and presenting to the same host
Or if it is easy to understand, I wish to migrate (transperent to the hosts) one eva to another.

Solution- Replicate LUN with Sync Mode to EVA2
- Add Host to EVA2 and Present the LUN
(As vcespon says the Host will not see the LUN)
- Wait until the LUN is Full replicated and in Sync
- ShutDown Host
- Unpresent LUN at EVA1
- Delete DR Droup and choose not to delete the LUN on EVA2
- Present LUN at EVA2
- Start Host
