The VSRESERVESYS command is an operator command that reserves a volume set on a system-wide basis. Logging on and off does not cancel the reserve.
This command can be used when the operator wants to stream several jobs that use files on the volume set. This system-wide reserve remains in effect during the logging on and logging off of the jobs that use the volume set.
Reserves the volume set for the entire system. This command indicates to the system that the volume set is to remain online until an VSRELEASESYS command is issued. Unlike the VSRESERVE command, this command is unaffected by logging off.
