Call-Out (Call-Home) - IBM H80 User Manual

v Surveillance interval
The maximum time the service processor should wait for a heartbeat from the
operating system before timeout.
v Surveillance delay
The length of time to wait from the time the operating system is started to when the
first heartbeat is expected.
Surveillance does not take effect until the next time the operating system is started after
the parameters have been set.
You can initiate surveillance mode immediately from service aids. In addition to the
three options above, a fourth option allows you to select immediate surveillance, and
rebooting of the system is not necessarily required.
If operating system surveillance is enabled (and system firmware has passed control to
the operating system), and the service processor does not detect any heartbeats from
the operating system, the service processor assumes the system is hung and takes
action according to the reboot/restart policy settings. See "Service Processor
Reboot/Restart Recovery" on page 46.
If surveillance is selected from the service processor menus that are only available at
bootup, then surveillance is enabled by default as soon as the system boots. From
service aids, the selection is optional.

Call-Out (Call-Home)

The service processor can call out (call-home) when it detects one of the following
conditions:
v System firmware surveillance failure
v Operating system surveillance failure (if supported by operating system)
v Restarts
v Critical hardware failure
v Abnormal operating system termination
To enable the call-out feature, do the following:
1. Connect a modem to serial port 1 (S1) or serial port 2 (S2).
2. Set up the following using the service processor menus or the diagnostic service
aids:
v Enable call-out for the serial port where the modem is connected.
v Enter the modem configuration file name.
v Set up site-specific parameters (phone numbers for call-out, call-out policy,
3. To call out before restart, set Call-out before restart to enabled from the
Reboot/Restart Policy Setup menu.
number of call-out retries, and so on).
