Hi Gurus,

i recently encountered a situation that after failover the resync to the primary was manual event. This is my scenario we are doing project to replace eva with mc service gurard implementation , now in stiutaion where the client failover to the disaster recovery site start his production . what is the best approach to resync back to the primary do you folks think that we can automate this what are the risk factors if so

i really appreciate any body who can pass on this experence , i thought putting the entries in the snapmirror.conf file put i am not sure about risks considering that client would want to failback to to orginal disater recovery site.

regards

Moncy -

It is a manual operation to resync changes after recovery of the primary site, as is doing the 'snapmirror break' for failover.

These operations could be scripted.

There is some detail in the 'Data Protection Online Backup and Recovery Guide' portion of Data ONTAP documentation.

I hope this response has been helpful to you.
