node run to get to the node shell, then priv set diag.

cmode-single::> node run local

Type 'exit' or 'Ctrl-D' to return to the CLI

cmode-single-01> priv set diag

Hi Scott,

Thank you for the response. I would like to get into the Diag mode of the node via Powershell.

It is not possible to login to diag mode. What are you attempting to do? There still might be a solution, depending on what you are attempting.

Hi Cole,

Thank you for the reply. I am trying to write a script

1. which would login into the node of the CDOT filer's to get the registry value for the auto-grow trigger which based on the size. ( For more Info https://kb.netapp.com/support/index?page=content&id=3011632&actp=search&viewlocale=en_US&searchid=null) .

2. If i don't have the desired value, the script would go and change it.

Ok, so you would just need to use the cmdlets Get-NcVolAutosize and Set-NcVolAutosize. Is this the data you are looking for (I'm just looking at one volume below as an example)?

#7 PS2 D:\Development\PowerShell> Get-NcVolAutosize -VserverContext vs-vmware -Name test | fl *

NcController : den-cluster

Name : test

IsEnabled : False

IncrementSize : 10485760

MaximumSize : 251658240

MinimumSize : 209715200

GrowThresholdPercent : 85

ShrinkThresholdPercent : 50

Mode : off

Thanks again. I think you are using 8.2 version ONTAP . But in 8.1 version cluster ONTAP , the autogrow would trigger based on the registry value we set @ the node level . which i am trying to modify

I have sent you an email with one possible solution to this.

I'm interested in this as well. We use the setflag command for 7-mode.

Here is one example using Invoke-NcSsh:

Invoke-NcSsh -Command 'system node run -node * -command "priv set diag; registry walk options"'
