Solved: error with Get-NcAggr

Hello,

I've got an error

Get-NcAggr : Error converting value "inf" to type 'System.Nullable`1[System.Int64]'. Path 'space.efficiency.ratio', line 62,
position 20.
At C:\scripts\netapp.ps1:83 char:20

My toolkit version

PS C:\Windows\system32> get-natoolkitversion

Major Minor Build Revision
----- ----- ----- --------
9 12 1 2302

OnTAP version 9.12.1P3

How can I solve that? I've seen someone talked about ZAPI. I need to force that in the Toolkit?

thanks

Hi Maurizio,

Disclosure: I am a netapp employee but work on the PS/MSP side.

I came across this post searching for my own answers and your mention of ZAPI made me wonder if they just forgot to document a switch in the connect-nccontroller help... Sure enough, i found it via Get-Command:

((Get-Command Connect-NcController).parametersets).parameters | ft name,parametertype,aliases,helpmessage

Name                ParameterType                                 Aliases       HelpMessage
----                -------------                                 -------       -----------
Name                System.String[]                               {Filer}
Port                System.Nullable`1[System.UInt16]              {}
Credential          System.Management.Automation.PSCredential     {Cred, Creds}
HTTPS               System.Management.Automation.SwitchParameter  {}
HTTP                System.Management.Automation.SwitchParameter  {}
EnableSSLValidation System.Management.Automation.SwitchParameter  {}
Transient           System.Management.Automation.SwitchParameter  {}
Vserver             System.String                                 {}
Timeout             System.Nullable`1[System.Int32]               {}            Connection timeout value in milliseconds.  Only applies to HTTP/HTTPS.
Add                 System.Management.Automation.SwitchParameter  {}
ZapiCall            System.Management.Automation.SwitchParameter  {ONTAPI}      Use this to create Zapi connections to controller. Default would be REST for filers 9.6 and higher
ApplicationName     System.String                                 {AppName}
SSLVersion          System.String                                 {}

So just add the switch -ZapiCall; to your Connect-NcController command:

Connect-NcController "<clustername>" -Credential "<credentials>" -ZapiCall

The difference even when connecting to a 9.12P5 cluster (also im using the same PS module version as your are):

With -ZapiCall

I've noticed a lot of other breaking differences as well.
