When you have multiple hosts in the Virtual SAN cluster, you can reuse the profile of an existing Virtual SAN host and apply its profile settings to the rest of the hosts in the Virtual SAN cluster.
The host profile includes information about storage configuration, network configuration, and other characteristics of the host. Typically, if you are planning to create a cluster with a large number of hosts, such as 8, 16, 32, or 64 hosts, use the host profile feature to add more than one host at a time to the Virtual SAN cluster.
Prerequisites
- Verify that the host is in maintenance mode.
- Verify that the hardware components, drivers, firmware, and storage I/O controllers are listed in the VMware Compatibility Guide at http://www.vmware.com/resources/compatibility/search.php.
