 The B<mkzone> command is designed to divide the xCAT cluster into multiple zones. The nodes in each zone will share common root ssh keys. This allows the nodes in a zone to be able to as root ssh to each other without password, but cannot do the same to any node in another zone. All zones share a common xCAT Management Node and database including the site table, which defines the attributes of the entire cluster.
 The mkzone command is only supported on Linux ( No AIX support).
-The nodes are not updated with the new root ssh keys by mkzone.  You must run updatenode -k  or xdsh -K to the nodes to update the root ssh keys to the new generated zone keys. This will also sync any service nodes with the zone keys, if you have a hierarchical cluster.

 Note: if any zones in the zone table, there must be one and only one defaultzone. Otherwise, errors will occur.
