Hi everyone,
I recently purchased a new FAS2820 as a SnapMirror target system.
Now, I want to create a SnapMirror relationship for all my volumes (>100) in my primary storage.
What is the best way to achieve this?
I don't want to just run snapmirror protect commands on my target system because I don't want to overload my network during initialization.
Every idea is welcomed.

If you did settle on initializing many at once, you could use a global replication throttle to set a ceiling and avoid overloading the network.

SnapMirror will also automatically queue any relationships transfers above the supported limit for your platform (100/node)
Not sure how the volumes are arranged per SVM/vserver on the primary, but have you looked into SVMDR?

You could use snapmirror protect -auto-initialize false and then initialize them separately.

Hi RVA, I would use powershell to create all the snapmirror relationships. You could then initialize in batches, say 1-5 at a time, once that batch is at a healthy state (with checks), then move onto the new batch. Like Joey mentioned above, you may want to limit the bandwidth as well depending on the size of your link.

You could use Excel to generate the command and put the command in different columns, and the vserver/volume can be a separate row.
