13 : Update a Database Copy (Catalog Only)

Update-MailboxDatabaseCopy -Identity <DBName>\<ServerName> -SourceServer <ServerName> -CatalogOnly

Applicable in Windows 2008 / 2008 R2

Now everything seems to be working fine and sometimes we might face core Cluster Issues then please follow the below steps :

First you need to import failover cluster

Open windows Powershell -> Run as Administrator

Run the command the below

Import-Module failoverClusters

If you want to know the Quorum type then need to run the below command

Command Input : Get-ClusterQuorum -Cluster “DAGName” | fl

Output :

Cluster	DAG1
QuorumResource	File Share Witness (\\ mb3.netsaints.com\DAG1.netsaints.com)
QuorumType	Based on Nodes

 

If you have another Site (DR) and if you want to enable DAC mode below is the command

DAC MODE :

Set-DatabaseAvailabilityGroup -Identity DAG2 -DatacenterActivationMode DagOnly
