SCOM Unix/Linux RunAs Account View - System.Xml.XmlException

Posted by : on

Category : troubleshooting   operationsManager   linux


I received a case today for a customer who is having issues when attempting to open the RunAs Account view for Unix/Linux RunAs Accounts in the SCOM Console (Administration Tab-> Run As Configuration -> Unix/Linux Accounts). We were unable to return any Unix/Linux RunAs Accounts in the SCOM Console, even though we can create new ones, they are not populating in the list of RunAs Accounts for Unix/Linux.

We noticed an exception that will pop-up intermittently (while Console is idle or active):

How to Resolve

First we ran the following Powershell command output to gather RunAs Accounts related to Unix/Linux:

Get-SCOMRunAsAccount | Where {$_.AccountType -like "SCX*"}

We compared the above output to the accounts we can choose in the RunAs Profile for Unix/Linux Action Account. We noticed an entry that was not in the Get-SCOMRunAsAccount command run above: Orphaned RunAs Accounts

I asked the customer if he is comfortable with removing the RunAs Account and re-adding the Account. He said this was fine, so we proceeded to remove the RunAs Account like this:

Get-SCOMRunAsAccount | Where {$_.Name -eq "Test"} | Remove-SCOMRunAsAccount

Conclusion

Removing the Orphaned RunAs account allowed the Unix/Linux RunAs Account view to populate as intended. You can only remove these Orphaned RunAs accounts with the Powershell Commands: Get-SCOMRunAsAccount and Remove-SCOMRunAsAccount
