We use Exchange Server 2013 Enterprise on Windows Server 2012 R2 Standard. We installated SP1 directly after installation without installing CU1 and CU2.
According to documentation with SP1 for Exchange Server 2013, the maximum amoumt of Active Databases per server or per DAG is 100 after installing SP1. Before CU2 this was 50.
We have 96 databases configured on 8 servers (MB / CAS) in a DAG
. Each database has two passive copies. 132 copies of this passive databases are in a healthy state, and the other 60 have the status FailedAndSuspended
. When I try to resume these I get a message that the number of supported databases is reached (see attachement). According to an article on technet this can occur when a value msExchMaxStoresTotal is not updated properly in the configuration container of AD. This proved to be the case of some of our servers. I have changed the value from 50 to 100 using ADSI-Edit, waited for replication and then rebooted the server.
Still the databases that were FailedAndSuspended refused to resume. The same error is given.
I also tried the "solution" given in the technet articel. Re-enter the product key of Exchange and restarting the MSExchangeIS service didn't resolve anything.
Anybody an idea?
