Failover Cluster Rule ID 17 Internal Error configuring Cluster Aware Updating

Question

Here's a fun one:

RuleId : 17
Title : All failover cluster nodes must be able to access Windows PowerShell scripts
State : Failed
Severity : Error
FailedMachines : {HOSTA (internal error)}
PercentComplete : 85

I've set up basic CUA but I need a PowerShell script available to wait for an additional service to be online. I've placed the script in c:\ClusterStorage\Storage1\script.ps1. However, when running test-causetup I get the above. It seems to only be one host that has this issue in a 2 node cluster. If I put the script in c:\windows it has the exact same issue.

Any ideas on how to fix?

Hello

Thank you for your question and reaching out. I can understand you are having issues related to Cluster aware updates.

Ensure that all possible owner nodes of the CAU clustered role have permissions to access the configured PowerShell pre-update and post-update scripts.

Also , Please try to Remove the CAU configuration, reinstall and reconfigure CAU.
