When in maintenance mode, alerts, notifications, rules, monitors, automatic responses, state changes, and new alerts are suppressed for the class instance. .EXAMPLE Start-SCOMMaintenanceModeForGroup.ps1 -ComputerGroup "All Windows Computers" -EndTime 10 -Reason "UnplannedOther" -Comment "Testing Maintenance Mode" -Verbose Puts all Members of the "All Windows Computer" Group in Maintenance Mode for 10 minutes, with Reason "UnplannedOther" and with Comment "Testing Maintenance Mode". Adding Verbose information. .EXAMPLE Start-SCOMMaintenanceModeForGroup.ps1 -ComputerGroup "All Windows Computers" -EndTime 10 -Reason "UnplannedOther" -Comment "Testing Maintenance Mode" -Eventlog Puts all Members of the "All Windows Computer" Group in Maintenance Mode for 10 minutes, with Reason "UnplannedOther" and with Comment "Testing Maintenance Mode". Writing Eventlog information to the "Operations Manager" Eventlog (eventid 998 and eventid 999). Can be used for tracking and debugging when Task Scheduler is being used. .EXAMPLE Start-SCOMMaintenanceModeForGroup.ps1 -ComputerGroup "All Windows Computers" -EndTime 10 -Reason "UnplannedOther" -Comment "Testing Maintenance Mode" -WhatIf Using the WhatIf switch shows which Members of the "All Windows Computer" Group would be put in Maintenance Mode if you had run the script. So the members are not really put into maintenance mode. For testing purposes. .PARAMETER ComputerGroup The SCOM Computer Group name for which members you want to put in Maintenance Mode. .PARAMETER EndTime Specifies the time the maintenance will end. The minimum amount of time a resource can be in maintenance mode is 5 minutes. .PARAMETER Reason Specifies the reason for placing the resource into maintenance mode. Valid values are: UnplannedOther, PlannedHardwareMaintenance, UnplannedHardwareMaintenance, PlannedHardwareInstallation, UnplannedHardwareInstallation, PlannedOperatingSystemReconfiguration, UnplannedOperatingSystemReconfiguration, PlannedApplicationMaintenance, ApplicationInstallation, ApplicationUnresponsive, ApplicationUnstable, SecurityIssue, LossOfNetworkConnectivity .Parameter Comment Allows you to type a comment about the maintenance activity. .Parameter EventLog Writes information to the "Operations Manager" Eventlog to track what is happening. .Link http://blogs.technet.com/stefan_stranger#> #requires -version 2.0 [CmdletBinding(SupportsShouldProcess=$true)] param ( [Parameter(Mandatory=$True, ValueFromPipeline=$True, ValueFromPipelineByPropertyName=$True, HelpMessage='What is the ComputerGroup you want to put in Maintenance Mode?')] [Alias("Group")] [string[]]$ComputerGroup, [Parameter(Mandatory=$True, ValueFromPipeline=$false, ValueFromPipelineByPropertyName=$True, HelpMessage='Specifies the time the maintenance will end.
