IBM RS/6000 44P manual Call Out

This is the maximum time (in minutes) the service processor should wait for a heartbeat from the operating system before timeout.

vSurveillance delay

This is the length of time (in minutes) for the service processor to wait from when the operating system is started to when the first heartbeat is expected.

Surveillance takes effect immediately after the parameters are set from the service processor menus.

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. The machine is left powered on and the service processor enters standby phase, displaying the operating system surveillance failure code on the operator panel. If Call-out is enabled, the service processor calls to report the failure.

Call Out

The service processor can call out when it detects one of the following conditions:

vSystem firmware surveillance failure

vOperating system surveillance failure (if supported by the operating system)

vCritical environmental failures

vRestarts

To enable the call-out feature, do the following:

1.Have a modem connected to serial port 1 or 2

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.

vSet up serial port line speed.

vEnter the modem configuration filename.

vSet up site-specific parameters (such as phone numbers for call out and call out policy).

vTo 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 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 causes 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.
