I think I see the confusion. Erick is right that using collections API would sort the problem, but here is my rationale on why the confusion exists.
There are 3 stages to creating a valid collection (well this is how I think of it) 1) Upload a solrconfig.xml/schema.xml (+ A N Other required config) to ZK, 2) Create the "logical" collection, this step is dividing up the hash range of unique Ids for the shards, and needs to know NumShards for the collection in order to divide up the complete hash range into the relevant sections. 3) Create cores and assign them to each shard, etc. Prasi, you are doing step 1 and then step 3, but because you never use Collections API, you are never doing step 2. Hence Solr has no idea how many shards you have in your collection, so it assumes 1 when you create your first core. Hence everything else after this is just a replica of that core. ZkCli can do step 1, and the core API can be used for step 3 (we used it only because collection API didn't used to support things like dataDir, with discovery mode this becomes less important, as we can deploy core.properties files at will) *but* only if you've already defined the number of shards for your collection either on command line or through use of collectionAPI. But (and this is the important bit), the way to do step 2 properly is via Collections API. It is also possible to start a solr instance and supply numShards to it via an environment variable (-DnumShards=X) and that seems to work, but I don't think that is the recommended approach.
