#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Remove-DbaDbMirror { <# .SYNOPSIS Removes database mirrors. .DESCRIPTION Removes database mirrors. Does not set databases in recovery to recovered. .PARAMETER SqlInstance The target SQL Server instance or instances. 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 Database The target database. .PARAMETER Partner The partner fqdn. .PARAMETER Witness The witness fqdn. .PARAMETER InputObject Allows piping from Get-DbaDatabase. .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .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) Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Set-DbaDbMirror .EXAMPLE PS C:\> Set-DbaDbMirror -SqlInstance localhost Returns all Endpoint(s) on the local default SQL Server instance .EXAMPLE PS C:\> Set-DbaDbMirror -SqlInstance localhost, sql2016 Returns all Endpoint(s) for the local and sql2016 SQL Server instances #> [CmdletBinding(SupportsShouldProcess, ConfirmImpact = 'High')] param ( [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [string[]]$Database, [parameter(ValueFromPipeline)] [Microsoft.SqlServer.Management.Smo.Database[]]$InputObject, [switch]$EnableException ) process { if ((Test-Bound -ParameterName SqlInstance) -and (Test-Bound -Not -ParameterName Database)) { Stop-Function -Message "Database is required when SqlInstance is specified" return } foreach ($instance in $SqlInstance) { $InputObject += Get-DbaDatabase -SqlInstance $instance -SqlCredential $SqlCredential -Database $Database } foreach ($db in $InputObject) { if ($Pscmdlet.ShouldProcess($db.Parent.Name, "Turning off mirror for $db")) { # use t-sql cuz $db.Alter() doesnt always work against restoring dbs try { try { $db.ChangeMirroringState([Microsoft.SqlServer.Management.Smo.MirroringOption]::Off) $db.Alter() } catch { try { $db.Parent.Query("ALTER DATABASE $db SET PARTNER OFF") } catch { Stop-Function -Message "Failure on $($db.Parent) for $db" -ErrorRecord $_ -Continue } } [pscustomobject]@{ ComputerName = $db.ComputerName InstanceName = $db.InstanceName SqlInstance = $db.SqlInstance Database = $db.Name Status = "Removed" } } catch { Stop-Function -Message "Failure on $($db.Parent.Name)" -ErrorRecord $_ } } } } } |
