function Set-DbaDbMirror { <# .SYNOPSIS Sets properties of database mirrors. .DESCRIPTION Sets properties of database mirrors. .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. Accepts PowerShell credentials (Get-Credential). Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported. For MFA support, please use Connect-DbaInstance. .PARAMETER Database The target database. .PARAMETER Partner Sets the partner Fully Qualified Domain Name. .PARAMETER Witness Sets the witness Fully Qualified Domain Name. .PARAMETER SafetyLevel Sets the mirroring safety level. .PARAMETER State Sets the mirror state. .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: Mirroring, Mirror, HA Author: Chrissy LeMaire (@cl), netnerds.net Website: 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 sql2005 -Database dbatools -Partner TCP://SQL2008.ad.local:5374 Prompts for confirmation then sets the partner to TCP://SQL2008.ad.local:5374 for the database "dbtools" .EXAMPLE PS C:\> Set-DbaDbMirror -SqlInstance sql2005 -Database dbatools -Witness TCP://SQL2012.ad.local:5502 -Confirm:$false Does not prompt for confirmation and sets the witness to TCP://SQL2012.ad.local:5502 for the database "dbtools" .EXAMPLE PS C:\> Get-DbaDatabase -SqlInstance sql2005 | Out-GridView -PassThru | Set-DbaDbMirror -SafetyLevel Full -Confirm:$false Sets the safety level to Full for databases selected from a grid view.
