How does Powershell handle connecting to a mirrored failover partner automatically as it will in a .Net program that specifies the failover partner in the connection string?by Klaas at 2013-02-01 00:28:02
I think you should check the status of the databases, the principal will have status ‘normal’, the mirror is ‘restoring’. Of course there’s a possibility neither is available.If ((Get-Childitem SQLSERVER:SQL\server1\instance1\databases | Where { $.name -LIKE 'mirroreddbname'}).status -eq 'Normal') { $instance = "server1\instance1" }You can do pretty much the same with SMO instead of the SQL Provider.
ElseIf ((Get-Childitem SQLSERVER:SQL\server2\instance2\databases | Where { $.name -LIKE 'mirroreddbname'}).status -eq 'Normal') { $instance = "server2\instance2" }
Else { "None of the instances is available" }
It 's probably even better to check the availability of the server first, to catch any case where the principal is unavailable for other reasons than a failover.
