Profile Sychronization Instance list does not list all WFE servers on farm to choose from

Question

I want to create a UPA on a second WFE that serves as a failover WFE server, however the list of "Select the machine in this farm on which you would like to run Profile Synchronization process." only has the first WFE listed .. How can I add a new UPA for the second server to be able to run it when the first server is down?

Answer 1

You can only run one instance of the User Profile Synchronization service on a farm. it is kind of limitation. You cant have multiple instances of UPA sync.

But you can start User profile Service instance on multiple servers in farm.

Plan for the synchronization server

Try to run the below script against each server, replace Servername with ur each time. (this will list the UPA service instance on each server)

Add-PSSnapin Microsoft.SharePoint.Powershell
$TypeName = "User Profile Synchronization Service"
$ServerName = "SERVERNAME" #Replace with your server name where the service is stuck on Starting

Get-SPServiceInstance | where-object {$_.TypeName -eq $TypeName -and $_.Server.Address -eq $ServerName}
