Call-Out (Call-Home)
Note: The call-out function is handled by the Service Focal point application on the
Hardware Management Console (HMC).
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 any serial port.
2. Set up the following using the service processor menus or 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.
