The MOUNTWAITTIME option determines the maximum time that DFSMShsm waits for a tape mount before it issues a message to the operator. The MOUNTWAITTIME parameter is assigned a numeric value that specifies a reasonable amount of time to mount the tape. There are three mount processes: mounts by humans, robotic mounts, and virtual mounts. There is a wide range of the amounts of time for each mount process, and the MOUNTWAITTIME option is applied independently of which mount process is occurring.
