Exchange 2007 cluster failed over
Posted on 2011-02-16
I have an Exchange 2007 2 node cluster. The active virtual machine (exchange1) went offline a while ago and Exchange failed over to the passive node (exchange2).
I am in a situation now where exchange2 is currently active (quorum owner), the copy status of the 2nd storage group (public folders) is healthy but for the first storage group (mailbox database) the copy status is 'suspended'.
Essentially I want to know the best way to bring the first storage group back up to date on exchange1 and make exchange1 the active node in the cluster. Currently if I try a 'resume storage group copy' on exchange2, it bombs out because I think the two databases are vastly out of sync with each other.
On exchage1 there is an option to 'update storage group copy' and on exchange2 there is the option to 'restore storage group copy'. Which one do I use? What impact if any will this have on our live exchange environment?
