Hi Team,

I have issue, suddenly my Exchange mailbox move to other passive mailbox with healthy condition, no downtime

I have Exchange 2013 Cu7 and 3 Member DAG

this is event id log when move happened

can you tell me what this event id describe?

is Exchange Server have capability to move database itself if the server is healthy?

Thanks

You can use CollectOverMetrics.ps1 to determine why a database failedover to a different server.

Hi iam have a trouble when execute the command,

this error show

WriteHtmlReport : Cannot bind argument to parameter 'Data' because it is null.
At F:\Scripts\CollectOverMetrics.ps1:1493 char:31
+         WriteHtmlReport -Data $AmOperationsData -ReportPath $HtmlSummaryReportNa ...
+                               ~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidData: (:) [WriteHtmlReport], ParameterBindingValidationException
    + FullyQualifiedErrorId : ParameterArgumentValidationErrorNullNotAllowed,WriteHtmlReport

after that HTML and CSV report go blank

Btw, is the Exchange Server 2013 have capability to move active database automatically?

Thanks

Hi,

The Event 167 in your posting indicates that the Exchange Store database DBBRONZE01 copy on this server could not be reached.

If a database cant be reached, the mailbox which is located in another copy database would be mounted and connected automatically so that the client user would still connect to their mailbox without any problem. It is the High Availability for your mailbox database which is provided by DAG feature. For more information about the feature, please refer to Using a database availability group for high availability part in:

https://technet.microsoft.com/en-us/library/dd979799(v=exchg.150).aspx

Please check the status about the database DBBRONZE01 and collect more logs information about it.

Regards,

David

Is there any relation between CPU consume and mailbox connectivity?

because this cas happend when CPU process is peak

in my case, server availability is good, server still can be reached and ping reply

Thanks

Absolutely, if CPU is spiking and resources are being consumed (more than normal), the server is essentially in a 'hung' state. Response times will drop and communication to the database will fail/ become too slow. The DAGs PAM will move the database to a server that is healthy. Use Perfmon or ProcExplorer to determine what is causing your CPU to spike. Do you know what service is causing this spike? Do you have any third party apps installed on this machine? Does it happen at a specific time everyday? We need to trace down what/when/why this is happening.

Hi,

in my case, only one database move to others node.

I have 2 active database. DB01 with high traffic, and DB02 with standard traffic.

only DB01 move to others node, DB02 not move.

I think there is no CPU hung state, if the server Hung, two database will be move to other node

Thanks

Hi,

Please use the below command to check the database status:

get-MailboxDatabase Status | format-table Name,StorageGroup,

Mounted,BackupInProgress,OnlineMaintenanceInProgress

if you have some related logs, please post them here for further analysis.
