Which command should be used to perform a graceful shutdown and reboot of an AIX...

The shutdown command is used to shut down a system in an orderly manner. When used with the '-Fr' option, it will perform a graceful shutdown and reboot of the LPAR. This command is available onIBM AIX v7 systems and is documented in the IBM AIX v7 Administrator Specialty Study Guide. The syntax for the command is "shutdown -Fr", where the '-F' option indicates that the system should be rebooted after shutdown and the '-r' option indicates that the system should be rebooted. For more information, please see the IBM documentation at https://www.ibm.com/support/knowledgecenter/ssw_aix_72/com.ibm.aix.cmds3/shutdown.htm.
