Add replica on shards

Hi,
         I have created 8 shards on a collection named as ***wikingram**.
Now at that time, I were not created any replica. Now, I want to add a
replica on each shard. How can I do?
I created this - ** sudo curl
http://localhost:8983/solr/admin/collections?action=ADDREPLICA&collection=wikingram&shard=shard1&node=localhost:8983_solr**
but it is not working.

It throws errror -


<response>
<lst name="responseHeader">
<int name="status">400</int>
<int name="QTime">86</int>
</lst>
<str name="Operation ADDREPLICA caused
exception:">org.apache.solr.common.SolrException:org.apache.solr.common.SolrException:
Could not find collection : null</str>
<lst name="exception">
<str name="msg">Could not find collection : null</str>
<int name="rspCode">400</int>
</lst>
<lst name="error">
<str name="msg">Could not find collection : null</str>
<int name="code">400</int>
</lst>
</response>

Any help on this?

Thanks Norgorn.
I did the same thing but in different manner..
like -

localhost:8983/solr/admin/cores?action=CREATE&name=wikingram_shard4_replica3&collection=wikingram&property.shard=shard4

U can do the same simply by something like that

http://localhost:8983/solr/admin/cores?action=CREATE&collection=wikingram&name=ANY_NAME_HERE&shard=shard1

The main part is "shard=shard1", when you create core with existing shard
(core name doesn't matter, we use "collection_shard1_replica2", but u can do
whatever u want), this core becomes a replica and copies data from leading
shard.
