PS script: New-NcExportRule giving rule index always first number

ansible_netapp_Provision — Wed, 04 Jun 2025 09:58:10 GMT

When we execute export policy rule create through CLI, it always create "rule index" last number which is good and it should but when i did same using PS , "rule index" taking first number which is not needed. What is wrong here with PS? how can i solve it?

New-NcExportRule -ClientMatch "server1" -ReadOnlySecurityFlavor "sys" -ReadWriteSecurityFlavor "sys"

Hi,

The Index parameter of the "New-NcExportRule" CmdLet will assign the next "available" value, that is not necessarily the next concurrent index rule. To ensure the rule index is incremented you need to apply some programmatic logic if you don't want to accept the defaults. See the following example.

Syntax:

PS C:\> $credential = Get-Credential -Credential admin PS C:\> .\AddExportRule.ps1 -Cluster cluster1.testlab.local -VserverName vserver2 -VolumeName nfs_data_001 -ClientMatch "192.168.108.0/24" -Credential $credential Connected to cluster "cluster1.testlab.local" as user "admin" Enumerated Volume "nfs_data_001" on vserver "vserver2" Enumerate next concurrent export rule index "8" for policy "default" on vserver "vserver2" Added export rule index "8" for clientmatch "192.168.108.0/24" to policy "default" for volume "nfs_data_001" on vserver "vserver2"

Source Code:

Param( [Parameter(Mandatory = $True, HelpMessage = "The cluster name or IP Address")] [String]$Cluster, [Parameter(Mandatory = $True, HelpMessage = "The vserver name")] [String]$VserverName, [Parameter(Mandatory = $True, HelpMessage = "The volume name")] [String]$VolumeName, [Parameter(Mandatory = $True, HelpMessage = "The IP Address or IPv4 CIDR address")] [String]$ClientMatch, [Parameter(Mandatory = $False, HelpMessage = "The Read-Only rule type")] [ValidateSet("any","none","never","krb5","krb5i","krb5p","ntlm","sys")] [String]$RoRule="any", [Parameter(Mandatory = $False, HelpMessage = "The Read-Write rule type")] [ValidateSet("any","none","never","krb5","krb5i","krb5p","ntlm","sys")] [String]$RwRule="any", [Parameter(Mandatory = $False, HelpMessage = "The Protocol type")] [ValidateSet("any","cifs","flexcache","nfs","nfs2","nfs3","nfs4")] [String]$Protocol="nfs3", [Parameter(Mandatory = $True, HelpMessage = "The Credentials to authenticate to the cluster")] [System.Management.Automation.PSCredential]$Credential ) #'------------------------------------------------------------------------------ #'Connect to the cluster. #'------------------------------------------------------------------------------ Try{ Connect-NcController -Name $Cluster -HTTPS -Credential $Credential -ErrorAction Stop | Out-Null Write-Host $("Connected to cluster ""$Cluster"" as user """ + $Credential.UserName + """") }Catch{ Write-Warning -Message $("Failed connecting to cluster ""$Cluster"".
