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

ansible_netapp_Provision

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"
