Enable-NcClusterHA Not Working (New-NcCluster)

JohnChampion — Wed, 04 Jun 2025 15:26:50 GMT

Environment: NetApp PowerShell Toolkit 4.3, FAS2552 running ONTAP 9.1GA

I'm working on a new cluster setup script and trying the New-NcCluster cmdlet.

Everything works great with the exception of the last cmdlet - Enable-NcClusterHA. This should (as I understand) be the equivalent of the CLI command "cluster ha modify -configured true". I was able to set this correctly using a ZAPI call as well as the CLI....just not the cmdlet (?).

Also, during troubleshooting, I noticed that the Set-NcClusterHaMode is not really needed (?) - the appropriate options are already set correctly. So it'd probably be possible to skip this one along with the reboots - but going along with what has worked in the past.

Any ideas why the Enable-NcClusterHa cmdlet is not working?

Hi John,

Enable-NcClusterHa is not the equivalent of "cluster ha modify", rather it is the equivalent of the CLI command "storage failover modify" and is using the "cf-service-enable" ZAPI.

Hope that helps.

OK - so what cmdlet is the equivalent? Do I have the cmdlets in the wrong order? I've tried both sequences and cannot find any other cmdlet related to HA to make the final setting.

There is no cmdlet equivalent. The API equivalent for "cluster ha modify" is private, unsupported, undocumented, and deprecated...so probably not a good one to use. Maybe use Invoke-NcSsh to change that setting?

I'll go with Invoke-NcSSH for now - seems odd that just about every other cmdlet you need to build an HA pair/cluster is now available EXCEPT that last step - hopefully they'll work it out.

Thanks!
