function Get-DbaAgReplica { <# .SYNOPSIS Outputs the Availability Group(s)' Replica object found on the server. .DESCRIPTION Default view provides most common set of properties for information on the Availability Group(s)' Replica. .PARAMETER SqlInstance The SQL Server instance. Server version must be SQL Server version 2012 or higher. .PARAMETER SqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. .PARAMETER AvailabilityGroup Specify the Availability Group name that you want to get information on. .PARAMETER Replica Specify the replica to pull information on, is dependent up name that you want to get information on. .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, AvailabilityGroup, Replica Author: Shawn Melton (@wsmelton) | Chrissy LeMaire (@ctrlb) Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaAgReplica .EXAMPLE Get-DbaAgReplica -SqlInstance sqlserver2014a Returns basic information on all the Availability Group(s) replica(s) found on sqlserver2014a .EXAMPLE Get-DbaAgReplica -SqlInstance sqlserver2014a -AvailabilityGroup AG-a Shows basic information on the replica(s) found on Availability Group AG-a on sqlserver2014a .EXAMPLE Get-DbaAgReplica -SqlInstance sqlserver2014a | Select * Returns full object properties on all Availability Group(s) replica(s) on sqlserver2014a #> [CmdletBinding()] param ( [parameter(Mandatory = $true, ValueFromPipeline = $true)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential][System.Management.Automation.CredentialAttribute()] $SqlCredential, [parameter(ValueFromPipeline = $true)] [object[]]$AvailabilityGroup, [object[]]$Replica, [Alias('Silent')] [switch]$EnableException ) process { foreach ($serverName in $SqlInstance) { try { $server = Connect-SqlInstance -SqlInstance $serverName -SqlCredential $SqlCredential -MinimumVersion 11 } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } if ($server.IsHadrEnabled -eq $false) { Stop-Function -Message "Availability Group (HADR) is not configured for the instance: $serverName" -Target $serverName -Continue } $ags = $server.AvailabilityGroups if ($AvailabilityGroup) { $ags = $ags | Where-Object Name -in $AvailabilityGroup } foreach ($ag in $ags) { $replicas = $ag.AvailabilityReplicas foreach ($currentReplica in $replicas) { if ($Replica -and $currentReplica.Name -notmatch $Replica) { continue } Add-Member -Force -InputObject $currentReplica -MemberType NoteProperty -Name ComputerName -value $server.NetName Add-Member -Force -InputObject $currentReplica -MemberType NoteProperty -Name InstanceName -value $server.ServiceName Add-Member -Force -InputObject $currentReplica -MemberType NoteProperty -Name SqlInstance -value $server.DomainInstanceName $defaults = 'ComputerName', 'InstanceName', 'SqlInstance', 'Parent as AvailabilityGroup', 'Name as Replica', 'Role', 'ConnectionState', 'RollupSynchronizationState', 'AvailabilityMode', 'BackupPriority', 'EndpointUrl', 'SessionTimeout', 'FailoverMode', 'ReadonlyRoutingList' Select-DefaultView -InputObject $currentReplica -Property $defaults } } } } } |
