#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Get-DbaDbMirror { <# .SYNOPSIS Gets properties of database mirrors and mirror witnesses. .DESCRIPTION Gets properties of database mirrors and mirror witnesses. .PARAMETER SqlInstance SQL Server name or SMO object representing the SQL Server to connect to. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .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: Mirror, HA Author: Chrissy LeMaire (@cl), netnerds.net dbatools PowerShell module (https://dbatools.io, clemaire@gmail.com) Copyright (C) 2016 Chrissy LeMaire License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaDbMirror .EXAMPLE PS C:\> Get-DbaDbMirror -SqlInstance localhost Gets properties of database mirrors and mirror witnesses on localhost .EXAMPLE PS C:\> Get-DbaDbMirror -SqlInstance localhost, sql2016 Gets properties of database mirrors and mirror witnesses on localhost and sql2016 SQL Server instances #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { $dbs = Get-DbaDatabase -SqlInstance $instance -SqlCredential $SqlCredential $partners = $dbs | Where-Object MirroringPartner $partners | Select-DefaultView -Property ComputerName, InstanceName, SqlInstance, Name, MirroringSafetyLevel, MirroringStatus, MirroringPartner, MirroringPartnerInstance, MirroringFailoverLogSequenceNumber, MirroringID, MirroringRedoQueueMaxSize, MirroringRoleSequence, MirroringSafetySequence, MirroringTimeout, MirroringWitness, MirroringWitnessStatus # The witness is kinda hidden.
