How can I set shard members?

[Lee Chunki]

Hi,

I am trying to test Solr Cloud with version 4.1.0.
(  
http://wiki.apache.org/solr/SolrCloud#Example_C:_Two_shard_cluster_with_shard_replicas_and_zookeeper_ensemble
 )

Is there any way set shard & shard member ?

for example.
server1, server2 for shard1
server3, server4 for shard2

when I tested the example, shard member depend on running Solr order.
i.e. run server1 -> server2 -> server3 -> server4 then server1, 3 are shard1 
and server 2,4 are shard2
of course, from second time there is no dependency of running Solr order.

and I tried "-DshardId=shard1” but it is not working.

Thanks,
Chunki.
