Hi Donna,
Rather than troubleshoot the issue with the previous example code (which i hadn't tested), here is another code example using Invoke-NcSystemApi as an alternative to using Invoke-NcSsh
The code below enables you to show or modify the ontapi limits for a cluster. EG
cluster1::*> set diag;system ontapi limits show
Monitor Mode Max Run Max Reply
Time Size
------------- ---------- ---------
silent 120000 20
cluster1::*> set diag;system ontapi limits modify -max-reply-size 50
If you wanted to automate the above process (WITHOUT relying on "Invoke-NcSsh") then the following WFA command code enables you to do that using "Invoke-NcSystemApi"
Param(
[Parameter(Mandatory=$True, HelpMessage="The cluster name or IP Address")]
[String]$Cluster,
[Parameter(Mandatory=$False, HelpMessage="The ontapi monitor mode. Valid values are 'off', 'silent' or 'log'")]
[ValidateSet("off","silent","log","")]
[String]$MonitorMode,
[Parameter(Mandatory=$False, HelpMessage="The maximum ontapi runtime")]
[ValidateRange(0,1000000)]
[Int]$MaxRunTime,
[Parameter(Mandatory=$False, HelpMessage="The maximum ontapi reply size")]
[ValidateRange(0,1000)]
[Int]$MaxReplySize
)

If you are not using WFA and just want a native powershell example then replace:
- "Get-WFALogger -Info -Message" with "Write-Host"
- "Get-WFALogger -Error -Message" with "Write-Warning -Message"
- Comment out "#Add-WfaWorkflowParameter"
- "Connect-WfaCluster $Cluster" with "Connect-NcController -Name $Cluster -HTTPS -Credential $(Get-Credential -Credential admin)"
- Add "Import-Module DataONTAP" to your script
Here is an example output from WFA:
Hope that's a more useful example that you should be able to test without issue and use the code as the basis for modifying it to meet your requirements.
