Call-Out (Call-Home)
The service processor can call out (Call-Home) when it detects one of the following
conditions:
System firmware surveillance failure
Operating system surveillance failure (if supported by operating system)
Restarts
Critical hardware failure
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:
Enable call-out for the serial port where the modem is connected.
Enter the modem configuration file name.
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.
