Adding Datastore from second host


I have Opennebula 5.4 running on my environtment with simple installation. I have 2 host. Now i experienced lack of storage on my server. I see 92% used on my first host and 6% used on my second host. I realize i just using one host to save all my images and disks. How do i add second host’s storage to datastore and use it to save images and disks? Anyone can help me?
