SHUTDOWN Use the SHUTDOWN command to systematically end all VM/370 functions and
to cbeckpoint the system for an ¥ara start. This is the nor.al method to shut the system down. All VM/370 functions are suspended and communications lines are disabled. Use the NETWORK SHUTDOWN command to
stop communications on 370x or remote 3270 binary synchronous lines.
The format of the SHUTDOWN command is: SHUTDOWN I This command has no operands. 1. Because the SHUTDOWN command stops all virtual machine operation,
any knowledge of an impending shutdown situation on the part of the system operator should be conveyed to the virtual machine users as
soon as possible via appropriate LOGMSG information, aessages and
warnings so they may quiesce their virtual systems in an orderly manner. 2. In VM/370 installations that use the 3850 Mass Storage System, the V8/370 shutdown process issues a SUSPEND order to all 3851 devices
to suspend the MSC interface. Note, the SUSPEND order may cause
the shutdown process to take longer than usual as it causes the
destaging of data on 3330V volumes. SYSTEM SHUTDOWN COMPLETE 144 VM/370 Operator's Guide
