I have previously posted a few scripts on managing and configuring fail-over management servers on gateways and agents in System Center Operations Manager 2007 R2. Now that System Center 2012 Operations Manager is RTM and users are starting to explore the differences between the versions I see more and more questions on how you do, in OpsMgr 2012, what you did in OpsMgr 2007. In a few posts henceforth I will go through Agent and Gateway server fail-over configuration and management. In this first post I’ll look at the very basics of fail-over configuration, the cmdlets to use and some one-liners. The cmdletFirst of all, the cmdlets of OpsMgr powershell have all got new names looking like Verb-SCOMnoun and to list them all in the console you can execute the following command: [powershell]get-command SCOM[/powershell] The cmdlet we are looking for to set and manage primary and fail-over management servers is [powershell]Get-SCOMParentManagementServer[/powershell] As usual, you can pass the cmdlet as a parameter to get-help for information about its parameters and a few use-cases. SYNOPSIS Changes the primary and failover management servers for an agent or gateway management server. SYNTAX Set-SCOMParentManagementServer -Agent -PrimaryServer [-PassThru ] [-Confirm ] [-WhatIf ]  Set-SCOMParentManagementServer -Agent -FailoverServer [-PassThru ] [-Confirm ] [-WhatIf ]  Set-SCOMParentManagementServer -GatewayServer -FailoverServer [-PassThru ] [-Confirm ] [-WhatIf ]  Set-SCOMParentManagementServer -GatewayServer -PrimaryServer [-PassThru] [-Confirm] [-WhatIf] But that’s so boring to read the manual is a bit sketchy on how it behaves and the limitations.
