If you want to restart DFSMShsm in emergency mode, consider the following conditions:

• To restart a demoted host in emergency mode, specify the EMERGENCY parameter in your startup procedures to avoid the window between the time a demoted DFSMShsm host joins XCF and attempts to take back its functions and the time—after setup—that the SETSYS EMERGENCY command is issued.
• If an original host restarts in emergency mode, it will not take back its level functions.
• A host in emergency mode cannot promote itself.
