Snapmirror from drfiler1 to drfiler2.
Quiesce and break the mirror between drfiler1 and drfiler2.
Modify snapmirror between drfiler2 and drfiler1 to be between drfiler2 and filer1
Resync snapmirror on drfiler2
On drfiler1 snapmirror release drfiler2 path
 
When satisfied that all is as you want it.
Quiesce and break mirror between filer1 and drfiler1
On filer1 snapmirror release drfiler1 path
On drfiler1 delete snapmirror definition for filer1
Delete former destination volume on drfiler1
 
Setting up and initializing the mirrors between drfiler1 and drfiler2 ensures there are some common snapshots between filer1 and drfiler2.  Therefore, when you change the relationship to be between drfiler2 and filer1 instead of drfiler2 and drfiler1, there will only be a delta transfer.

Hi,

 

We currently 3 filers, and are looking to move a snap mirrored volume to another filer, we would like to do this without having to recreate a new snapmirror and all the traffic associated with with it.

 

The example is:

 

Filer1 has Vol1 witch is snap mirrored to drfiler1 Vol1

 

We would like to copy/move Vol1 on drfiler1 to drfiler2, and continue with it being a snap mirror of Vol1 on Filer1, without having to reinitialise the snap mirror

 

Drfiler1 and Drfiler2 are both on the same site so we have no bandwidth restrictions.

 

Is this possible and could someone point me in the right direction of how to do it.

 

Thanks

 

Matt
