I wrote a blog on SVM DR, if you are interested:

You are right, you need to create destination SVM in advance with right attributes.

According to documentation “For remote data access or data distribution, you can provide read-only access to the NFS clients and SAN hosts from the destination SVM, if you chose to set the identity-preserve option to false.”. Also “SVM Disaster Recovery Preparation Express Guide” gives examples that indicate that you can (actually, must) configure network on destination SVM and access it.

Subject: SVM DR in 8.3.1

Hi all,

I know is still RC1 but prior to upgrade a running 8.3 I would try to have more info on a new 8.3.1 feature: the SVM DR.

I’ve a customer that on 7Mode ran the DR of CIFS vfiler (joined to a domain) using snapmirror of the vfiler vols, including the root one, and at the DR test/run the source vfiler was stopped and a vfiler create –d command, with the mirrored root specified, let the destination vfiler start with all domain infos, shares on the vole and ip addresses on the DR site with minimal effort.

I’ve read the docs that come with 8.3.1 but is not clear.

I don’t think that there’s something in SVM DR that permit to recreate the SVM on the destinanation: this must exist in advance, in stopped mode, right?

What’s about the maintenance of the IPs? Should I have two identical subnets in both clusters?

What if I cannot have two different subnets? Do I have a way to let the replicated SVM being in standby with the data lif with preregistered IPs?

Regards
