change the surveillance time interval or the surveillance delay, as shown in 
the following example.

by simply entering 1 and then press Enter.

Surveillance Delay:
May be set to any number from 0 to 255 minutes.
Surveillance is a function in which the SP monitors the system, and the 
system monitors the Service Processor. This monitoring is accomplished by 
periodic samplings called 
heartbeats
.
Surveillance is available during two phases:
1. System firmware bringup (automatic)
Provides the SP with a means to detect boot failures while the system 
firmware is running. System firmware surveillance is automatically 
enabled during system power-on. It cannot be disabled with a user 
selectable option. If the SP detects no heartbeats during system IPL (for 7 
minutes), it cycles the system power to attempt a reboot. The maximum 
number of retries is set from the SP menus. If the fail condition repeats, 
the SP leaves the machine powered on, logs an error and offers menus to 
the user. If Call-out is enabled, the SP calls to report the failure and 
displays the operating system surveillance failure code on the operator 
panel.
2. Operating system run time (optional)
