Call-Out (Call-Home) - IBM RS/6000 Enterprise Server M80 Service Manual

For operating system surveillance to work correctly, you must set the following parameters:
v Surveillance enable/disable
v Surveillance interval
The maximum time the service processor waits between heartbeats from the operating system before
reporting a surveillance failure.
v Surveillance delay
The maximum time the service processor waits for the first heartbeat from the operating system, after
the operating system has been started, before reporting a surveillance failure.
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 within the
surveillance delay period, 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 387.
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, number of call-out
retries, and so on).
3. To call out before restart, set Call-out before restart to enabled from the Reboot/Restart Policy Setup
menu.
Note: Some modems, such as IBM 7857-017, are not designed for the paging function. Although they can
be used for paging, they will return an error message when they do not get the expected response
from another modem. Therefore, even though the paging was successful, the error message will
cause the service processor to retry, continuing to place pager calls for the number of retries
specified in the Call-Out Policy Setup Menu. These retries result in redundant pages.
