Hi All,
I have 2 fairly simple question about vmware vcentre 5.5 running 2 ESX hosts attached to a EqualLogic SAN. No ESX  clusters. No datastore clusters. Just standalone 2 ESX servers managed through vcentre 5.5 .

I have created a new iscsi volume in SAN  and given permission to both ESX hosts to access  it.
In vcentre  , I can see this volume attached to a one host. In the other host , it get discovered but it doesn't show up as a available volume to create a data store.

Questions:
1. Why does this new volume does not  show up in both ESX servers ?

Secondly ,
What I would like to happen is to create a shared datastore that can be accessed by both ESX servers.Similar to what says (But unfortunately not shown how its done anywhere) in here.

Sharing a VMFS Datastore Across Hosts:
http://pubs.vmware.com/vsphere-51/index.jsp?topic=%2Fcom.vmware.vsphere.storage.doc%2FGUID-52DC7277-5321-4BB5-86B4-D73D258F6529.html

Seems to be a very straightforward thing to do. But I really can not find out a way to do it.
I can add a datastore through vsphere web interface. But then that datastore only appear in one ESX server. Not on the other one.

Any help would be greatly appreciated.

You need to create a cluster in VC and add both hosts under the cluster. Then add the datastore and it will be available to both hosts. You will need to run through the Add Storage wizard under the configuration ---> Storage table for each host.

Thanks for the quick response SagiEDoc,
I've already tried that. Also created a storage Cluster and tried as well. Both didn't work.
So Ive revert back to the standalone 2 host configuration.

These 2 ESX hosts already have  2 shared data-stores configured in them  (Not by me).
These 2 datastores are visible in both ESX servers with out being in a cluster.  That's where the real mystery is.

Are both hosts added on the EqualLogic as hosts?
