#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Get-DbaAgReplica { <# .SYNOPSIS Returns the availability group replica object found on the server. .DESCRIPTION Returns the availability group replica object found on the server. .PARAMETER SqlInstance The target SQL Server instance or instances. Server version must be SQL Server version 2012 or higher. .PARAMETER SqlCredential Login to the SqlInstance instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER AvailabilityGroup Specify the availability groups to query. .PARAMETER Replica Return only specific replicas. .PARAMETER InputObject Enables piped input from Get-DbaAvailabilityGroup. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: AG, HA, AvailabilityGroup, Replica Author: Shawn Melton (@wsmelton) | Chrissy LeMaire (@cl) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaAgReplica .EXAMPLE PS C:\> Get-DbaAgReplica -SqlInstance sql2017a Returns basic information on all the availability group replicas found on sql2017a .EXAMPLE PS C:\> Get-DbaAgReplica -SqlInstance sql2017a -AvailabilityGroup SharePoint Shows basic information on the replicas found on availability group SharePoint on sql2017a .EXAMPLE PS C:\> Get-DbaAgReplica -SqlInstance sql2017a | Select-Object * Returns full object properties on all availability group replicas found on sql2017a #> [CmdletBinding()] param ( [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [string[]]$AvailabilityGroup, [string[]]$Replica, [parameter(ValueFromPipeline)] [Microsoft.SqlServer.Management.Smo.AvailabilityGroup[]]$InputObject, [switch]$EnableException ) process { if ($SqlInstance) { $InputObject += Get-DbaAvailabilityGroup -SqlInstance $SqlInstance -SqlCredential $SqlCredential -AvailabilityGroup $AvailabilityGroup } if ($Replica) { $InputObject = $InputObject | Where-Object { $_.AvailabilityReplicas.Name -contains $Replica } } $defaults = 'ComputerName', 'InstanceName', 'SqlInstance', 'AvailabilityGroup', 'Name', 'Role', 'ConnectionState', 'RollupSynchronizationState', 'AvailabilityMode', 'BackupPriority', 'EndpointUrl', 'SessionTimeout', 'FailoverMode', 'ReadonlyRoutingList' foreach ($agreplica in $InputObject.AvailabilityReplicas) { #Variable marked as unused by PSScriptAnalyzer #$sever = $agreplica.Parent.Parent Add-Member -Force -InputObject $agreplica -MemberType NoteProperty -Name ComputerName -value $agreplica.Parent.ComputerName Add-Member -Force -InputObject $agreplica -MemberType NoteProperty -Name InstanceName -value $agreplica.Parent.InstanceName Add-Member -Force -InputObject $agreplica -MemberType NoteProperty -Name SqlInstance -value $agreplica.Parent.SqlInstance Add-Member -Force -InputObject $agreplica -MemberType NoteProperty -Name AvailabilityGroup -value $agreplica.Parent.Name Add-Member -Force -InputObject $agreplica -MemberType NoteProperty -Name Replica -value $agreplica.Name # backwards compat Select-DefaultView -InputObject $agreplica -Property $defaults } } } |
