Can't we add another host even though storage pool is available ??


We can. The issue seems to be the new host not able to connect to the storage. Can you share the vdsm.log for the event?

Seems like you already have a Storage Pool called 'Pulse' and the new host is not able to connect to it. vdsm.log on the infraesx2 host will give you more details.
