Shared HFS

If this system is in a sysplex and is participating in the shared HFS function, you can specify whether you want ownership of the file system you are editing to automatically move to another system in the case of system failure. If you check "Yes" and the system fails, ownership of the file system moves to another system. If you check "No" and the system fails, the file system will become inaccessible. For full support, however, zFS must be running on all systems in the sysplex and all zFS file systems must be compatibility mode file systems (that is, they cannot be file systems in multi-file system aggregates).
