PHP MongoDB WriteConcernException with replica set

I'm attempting to connect to a replica set from PHP, using MongoDB client (1.6.11), against both server versions 3.0.7 and 2.6.6.

However, when executing a 'save()', occasionally the save is executed against one of the "secondary" servers, and an exception is thrown:

PHP Warning: Uncaught exception 'MongoWriteConcernException' with message '127.0.0.3:27017: not master'

The commands used to replicate this are:

$options = [
'db' => 'admin',
'username' => '**********',
'password' => '**********',
'socketTimeoutMS' => 5000,
'connectTimeoutMS' => 100,
];

$mongo = new MongoClient('mongodb://127.0.0.1,127.0.0.2,127.0.0.3', $options);
$collection = $mongo->selectDB('test')->selectCollection('test');
for ($i=0; $i<10; $i++) {
    $collection->save(['a' => uniqid()], ['w' => 3]);
}

And the rs.status() returns:

"myState" : 1,

    },

        "configVersion" : 3
    }
],
"ok" : 1
}

What am I missing?

I found my mistake: Somewhere along the line, I dropped ["replicaSet" => "devSet"] from the options array.
