Hi all - I am in the process of moving data around on our v6210 filer. I snapmirror data from aggr2 to aggr1 as I need to make some changes but wanted to retain the data.
That data i moved via snap mirror was a snapmirror of data from a remote filer.
now I wanted to re-establish that remote site with snapmirror with the data I snapmirrored in the new aggr - i thought a 'resync' woudl take care of this but only options was to intialize. If I were to click initialize will it write over what I have?
the only difference is that the remotes site destination snapmirror on the v6210 is on a diff aggr with a new name.
anyhow I hope I didnt confuse what I am trying to describe.
I clicked inittialize and thought if it would see the data then it woul dbe ok but shows xferring..
see attached pic
Solved! SEE THE SOLUTION

darn autocorrect If you type "snap list" on the source and destination volumes, if you have a common snapshot then you should be able to resync. If no common snapshot then you have to iniitialize from scratch.

In some cases (rarely) snap names may be different but the same snapshot (same time stamp) so you can rename them to match… but that is risky unless you can guarantee they are the same exact snapshot otherwise snapmirror can’t resync… resync requires a snap restore on the destination to match a common source snap then it rolls forward from that snap.

Thanks – I have two of them but only decided to start one of them. I will take a few weeks to finish.. as I am “initializing” from the remote site to dest filer.. ☹
But the original snapshot info is still on the other aggr… (which is local to the dest filer)
I was trying to cheat and snap mirror THE snap mirror from one aggr to the other then I thought I can resync the source with the new destination which has a diff name.. ☹
