Unable to mount datastore on new host

Have a 2 host VM Lab.  Data store on each host (local) and 2 LUNs (Datastores) on a SAN

Up graded an old host  to a newer host in lab.  Used HBA, Hard Drives, Memory for older server in newer server.  (HP G5 to G6 server).

With some help yesterday was able to mount the local datastore (hard drives) from old server to the new host.  Success!

Now I would like to mount the SAN Luns to the new host.

Not sure of the steps to accomplish this.  The host does not see the VMFS datastores.  The VMWare Knowlege base indicates I should be able to mount these datastores using the webclient, by selecting the add datastore.  But I must be missing something, because there are no vmfs stores to load.

I assume I have to establish connectivity between the host and the SAN, before the VMFS store are visible.  How do I go about this.

If the LUNs have VMFS partitions, they should appear automatically, after Re-scanning the storage adpators.

The Add Storage option, should really say Add New Storage.

Do you see the LUNs next to storage adaptor ?

I am using the web client.  So how do I rescan the storage adapters.  I knew where to look in the old client, just can't find it in the new client.

Also this isn't new storage to VCenter.  The other hosts see it fine.  It will just be new storage for the upgraded host.

But it's not new storage in the sense of blank storage!

can you see the LUNs ?

If I am looking at the storage I see both local stores and both lUNS.
If I am looking at the first host, I can see its local store and both Luns
If I am looking at the new host, I can only see local store.

okay, that would indicate that this new host does not have permission to mount the LUN.

did you add the iSCSI IQN from this new host, to the SAN LUN Permissions

Andrew, because the VM didn't really exist on on the old server datastore (decommissioned).  I removed it from inventory and disk (not really there) and then it allowed me to add it back to the new server with associated datastore.  So it is fixed.  Thanks!!
