Call-Out (Call-Home)

Note: Call-out is disabled in logically partitioned systems. 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 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

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.
