Activate database fail. An active Manager Operation Failed.

Question

Windows 2012 R2 with Microsoft Exchange 2016

I have 2 databases, let’s called it DB1-P and DB2-S

Inside Exchange Admin Center, under servers, databases: active on server DB1-P. On the side panel when I select database copy DB2-S and press Activate it show error.

ERROR
DB2-S
An Active Manager operation failed. Error: The database actin failed. Error: An error occurred while trying to validate the specified database copy for the possible activation. Error: DBS-2; Server “xxxx.org” is not up according to the Windows Failover Cluster service.

On both servers services: Cluster Service is running on DB1-P and DB2-S

Run, exchange management shell on server DB1-P
Get-MailboxDatabaseCopyStatus

Name. Status
DB1-P Mounted 0 0 Empty Healthy
DB2-S Healthy 0 0 18/7/2020 1:15 PM Healthy

Run, exchange management shell on server DB1-P
Cluster node /status
DB1-P 1 Up
DB2-S 2 Down

Run, exchange management shell on server DB2-S
Cluster node /status
DB1-P 1 Down
DB2-S 2 Joining

How do I solve the DB2-S switchover issue? I cannot activate inside exchange admin Center.

Answer 1

Whenever I have seen this issue, it required removing the node from the DAG, clearing that node from the cluster (Clear-ClusterNode) and re-adding.

Answer 2

Do you try to mount the DB2 on the first Exchange server or the second server? I'm a little confused about your db name and server name.

As Andy mentioned, please try to remove db copies from the second Exchange server, then remove this server from DAG. After re-adding it into the DAG, check if database copies can be mounted on it successfully.

You can check these for more information about removing db copies and DAG member:

Answer 3

Hi Zhou,

Good Day!

I've encountered same error. The error is an active manager operation failed when I try to make a database copy from Primary Exchange Server to Secondary Exchange Server.

Thanks,
Raymond

Answer 4

After a reboot, especially after a patch; "MS Exchange Search Host Controller service gets disabled" so you need to enable it and start it to fix content index state of exchange server

Answer 5

Just trying to check if there's any firewall between 2 cluster nodes? Or is there any antivirus installed on each of the nodes? If yes, you may try to disable the antivirus and observe the result.

Thank you.
