Re: The tag mechanism of the "netgroups-file-get-iter" zapi call doesn't appear to work

loganb · ‎2016-05-27

Hello, I am a TSE with this Active case open - https://smartsolve.netapp.com/case?case_id=2006299816

I am creating this post for the customer as he believes that there is a bug related to the netgorups-file-get-iter call. I will maintain the case Active for monitoring and to provide assistance where needed.

Problem Summary:

The tag mechanism of the "netgroups-file-get-iter" zapi call doesn't appear to work. The first call returns 20 records, but calling it again with a tag always returns zero records, even when the filer definitely has more than 20 netgroup entries.

Increasing the "max-records" parameter results in more records being returned on the first call, but the second call still returns zero records.

Test performed:

I attached a perl script text below that can reproduce the bug, as follows:

1. Use "netgroup load" on the cluster to populate the local netgroup database. The loaded netgroup file should have 40 or more entries.

2. Edit the attached perl script to supply a username and password for a user with the capability to run netgroups-file-get-iter. A user with the "readonly" role should work.

3. Run the script, supplying the cluster management address as the first parameter.

Although the cluster has more than 20 netgroup entries, you'll get

Received 20 entries
Received no entries

What you should get is

Received 20 entries
Received 20 entries

You can compare this behavior to that of "volume-get-iter" or "qtree-list-iter" by changing the $API variable. Those calls will give you the correct output (if run against a cluster with at least 40 volumes or qtrees, respectively).

Perl script text:

#!/usr/bin/perl

use strict;
use warnings;
use NaServer;

my $API = 'netgroups-file-get-iter';
my $USER = '<insert username here>';
my $PASS = '<insert password here>';

{
    my $s = NaServer->new($ARGV[0], 1, 31);
    $s->set_admin_user($USER, $PASS);

    # first query
    my $res = $s->invoke($API);
    if (!$res || $res->results_status() eq 'failed') {
        die "$API failed";
    }
    my $itertag = $res->child_get_string('next-tag')
        or die "Invalid test: data all fits in one call";
    my $attrs = $res->child_get('attributes-list');
    if ($attrs) {
        print "Received ",scalar($attrs->children_get())," entries\n";
    } else {
        print "Received no entries\n";
    }

    # second query
    my $query = NaElement->new($API);
    if (defined($itertag)) {
        $query->child_add_string('tag', $itertag);
    }
    $res = $s->invoke_elem($query);
    if (!$res || $res->results_status() eq 'failed') {
        die "$API failed";
    }
    $attrs = $res->child_get('attributes-list');
    if ($attrs) {
        print "Received ",scalar($attrs->children_get())," entries\n";
    } else {
        print "Received no entries\n";
    }
}

, the “netgroups-file-get-iter” is a new API introduced with SDK version 5.5 (API version 1.3.1)
I downloaded the latest SDK and had a look at the structure compared to “qtree-list-iter” (which has the same parameters) EG:

Here is the example code in Perl to invoke the ZAPI from zexplore (set the path as required):

require 5.6.1;
use lib '<path_to_nmsdk_root>/lib/perl/NetApp';
use strict;
use warnings;
use NaServer;
use NaElement;

my $s = new NaServer('<server name or IP address>', 1 , 31);
$s->set_server_type('FILER');
$s->set_transport_type('HTTPS');
$s->set_port(443);
$s->set_style('LOGIN');
$s->set_admin_user('<user name>', '<password>');

my $api = new NaElement('netgroups-file-get-iter');

my $xi = new NaElement('desired-attributes');
$api->child_add($xi);

my $xi1 = new NaElement('netgroups-file-config-info');
$xi->child_add($xi1);

$xi1->child_add_string('domain','<domain>');
$xi1->child_add_string('host','<host>');
$xi1->child_add_string('member-netgroup','<member-netgroup>');
$xi1->child_add_string('netgroup-name','<netgroup-name>');
$xi1->child_add_string('user','<user>');
$xi1->child_add_string('vserver','<vserver>');
$api->child_add_string('max-records','<max-records>');

my $xi2 = new NaElement('query');
$api->child_add($xi2);

my $xi3 = new NaElement('netgroups-file-config-info');
$xi2->child_add($xi3);

$xi3->child_add_string('domain','<domain>');
$xi3->child_add_string('host','<host>');
$xi3->child_add_string('member-netgroup','<member-netgroup>');
$xi3->child_add_string('netgroup-name','<netgroup-name>');
$xi3->child_add_string('user','<user>');
$xi3->child_add_string('vserver','<vserver>');
$api->child_add_string('tag','<tag>');

my $xo = $s->invoke_elem($api);
if ($xo->results_status() eq 'failed') {
    print 'Error:\n';
    print $xo->sprintf();
    exit 1;
}

print 'Received:\n';
print $xo->sprintf();

Another method to determine if the issue is caused by the ZAPI or the PERL code would be to test the ZAPI using the “apitest” utility within the SDK
There is a PERL example in the SDK which contains the required syntax. See (“<path_to_nmsdk_root>/src/sample/Data_ONTAP/Perl/apitest.pl”)

next step:

waiting for customer to test the ZAPI

Hi Logan,

I believe the issue relates the "max-records" property default value being set to 20. I do not think there is a bug with the API as a low default value would have probably been defined to ensure the ZAPI does not return all records. You need to explicitly set the 'max-records' property of the NaElement object BEFORE you invoke the 'netgroups-file-get-iter' ZAPI to ensure that you can iterate through each netgroup rather than just the default of 20.

Here is an example in PowerShell which uses the "manageontap.dll" from the NMSDK 5.5 (ZAPI version 1.31 introduces the 'netgroups' API)

The bug is with the tag parameter, not with the max-records parameter. The first call (with no tag parameter) always works correctly; it just returns the first max-records records and a next-tag field. The problem happens when you try to use that next-tag field in a second invocation of the API call.

I'm not a powershell programmer, but you need to do something like this: leave the max-records alone, but get the "next-tag" field from the first call:

$naElement = New-Object NetApp.Manage.NaElement($zapiName)
$results = $NaServer.InvokeElem($naElement)
$tag = $results.GetChildContent("next-tag")

...then use that in a second invocation:

$naElement = New-Object NetApp.Manage.NaElement($zapiName)
$naElement.AddNewChild("tag", $tag)
$results = $NaServer.InvokeElem($naElement)

This time $results will contain no entries, while it should contain records 21-40. And indeed, if you replace the zapi call with another -iter, say, qtree-list-iter or volume-list-iter, the tag mechanism works fine, and each call gets you the next 20 records.

Hi,

You are correct and appologies for the delayed response, I think there is a BUG with the "netgroups-file-get-iter" ZAPI when used with the tag mechanism as it does not return more than 20 returns. I confirmed this by testing another ZAPI "qtree-list-iter" using the tag mechanism to iterate through the results and it works successfully. EG:

Now if i apply exactly the same principle using the tag mechanism but using the "netgroups-file-get-iter" it will only show the first 20 results (even though there were 25 netgroups on my vserver). EG
