Rename LIF using Update-NcNetInterface Fails

Trying to rename the node management LIFs using Update-NcNetInterface but it does not rename the lif even though it reports a success count of 1.

 

PS C:\> $q = get-NcNetInterface -Template
PS C:\> $q.InterfaceName = "CLUSTER-01_mgmt1"
PS C:\> $a = Get-NcNetInterface -Template
PS C:\> $a.InterfaceName = "CLUSTER-A_mgmt"
PS C:\> Update-NcNetInterface -Query $q -Attributes $a

 

NcController : xx.xx.xx.xx
SuccessCount : 1
FailureCount : 0
SuccessList : {CLUSTER-01_mgmt1}
FailureList : {}

 

I have also attempted this on data lifs with the same result so it's not specific to management lifs.  Also tried setting the AdministrativeStatus to "down" prior to rename - same result.

 

Renaming the LIF from the CLI works perfectly!

 

Could make a new LIF and then delete the old one but this should work.  It sets any other property EXCEPT the InterfaceName and it works from the CLI.

 

Any ideas?

Hi John,

 

I suspect it's because it may require shell access to rename the node management LIF and the PowerShell CmdLets invoke ZAPI's instead of shell commands.

You can use the Invoke-NcSsh CmdLet. Here is an example of a WFA command i wrote to rename a logical interface name:

 

Param(
   [Parameter(Mandatory=$True, HelpMessage="The hostname or IP Address of the cluster")]
   [String]$ClusterName,
   [Parameter(Mandatory=$True, HelpMessage="The name of the vserver")]
   [String]$VserverName,
   [Parameter(Mandatory=$True, HelpMessage="The name of the logical interface to rename")]
   [String]$LogicalInterfaceName,
   [Parameter(Mandatory=$True, HelpMessage="The new name of the logical interface")]
   [String]$NewLogicalInterfaceName     
)

$attributes = Get-NcNetInterface -Template
$attributes.InterfaceName = ""

}Catch{

   Throw "Failed renaming network interface ""$LogicalInterfaceName"" to ""$NewLogicalInterfaceName"""

}
#'------------------------------------------------------------------------------
#'Ensure the logical interface has been renamed.
#'------------------------------------------------------------------------------
If($NewLogicalInterfaceName -ne $lifName){
   Throw "Failed renaming logical interface ""$LogicalInterfaceName"" to ""$NewLogicalInterfaceName"" on vserver ""$VserverName"""
}Else{
   Get-WFALogger -Info -Message "The logical interface ""$LogicalInterfaceName"" has been renamed to ""$NewLogicalInterfaceName"" on vserver ""$VserverName"""
}

Ok, I will admit I hate the implementation of powershell for cDOT.   I'm a huge fan of powershell on 7-mode, beening using it heavily since 7-mode v1.0.  (Check my post archives)

 

In my mind, invoke-ncssh is a "patch" on how to run an SSH command.  These should all be done via API with powershell.

 

There is no reason on my mind we shouldn't be able to do this

 

get-ncnetinterface | ? {$_.interfacename -eq "blah"} | set-ncnetinterfacen -interfacename "newblah"

 

I might be ranting a little, but this is my opinion and i'm pretty strong on this.

This appears to be a limitation of ZAPI, not the PSTK.  ZAPI uses the vserver + name as the unique identifier for the LIF, and there is no option to change the name.

I figured as much - even tried using just the IP Address in the query template to get around this - but if ZAPI insists .... well.  Long term this should be worked out without resorting to NcSsh I think.  Especially considering there is a CLI command. Maybe Ontapi 1.40 😉

Thanks Andrew
