Enable-NcClusterHA Not Working (New-NcCluster)

JohnChampion

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.

# Create Cluster

# Join Node 2 to Cluster

Add-NcCluster -ClusterName MASTER

 

# Check Progress

# Connect to Cluster

# Set HA Mode

Set-NcClusterHaMode -Node MASTER-01 -Enable
Set-NcClusterHaMode -Node MASTER-02 -Enable

 

# Reboot

Restart-NcNode -IgnoreQuorumWarnings -Node MASTER-01

 

# Connect to Cluster

Connect-NcController 10.0.10.13

 

# Enable Cluster HA

Enable-NcClusterHa -Node MASTER-01

Enable-NcClusterHa -Node MASTER-02

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

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?

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.

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!
