Re: Exchange 2007 DR
Hi,
I used database portability to activate the SCR target. I successfully
mounted the database in the SCR target Exchange standalone server. Now i am
trying to follow the same procedure to replicate back to my orginal server.
My orginal server is SCC in a two node active passive cluster
configuration. I deleted the Storage group and database which was in the
orginal exchange srever. When i enable the SCR i am getting the following
error "SCR cannot be configured on node YYY because it is not a member of
cluster XXX "
Please advise.
Thanks.
