Operating System Surveillance: Provides the SP with a means to detect hang conditions, hardware or
software failures while the operating system is running. It also provides the operating system with a means
to detect the SP failure by the lack of a return heartbeat.
Operating system surveillance is enabled by default. This is to allow the user to run operating systems that
do not support this SP option.
Operating system surveillance can be enabled and disabled via:
v
SP Menus
v
SP Service Aids
Three parameters must be set for operating system surveillance:
1. Surveillance enable/disable
2. Surveillance interval
This is the maximum time in minutes the SP should wait for a heartbeat from the operating system
before timeout.
3. Surveillance delay
This is the length of time in minutes for the SP to wait from when the operating system is started to
when the first heartbeat is expected.
Surveillance will take effect immediately after setting the parameters from the SP menus.
If operating system surveillance is enabled (and system firmware has passed control to the operating
system), and the SP does not detect any heartbeats from the operating system, the SP assumes the
system is hung. The machine is left powered on and the SP enters standby phase, displaying the
operating system surveillance failure code on the operator panel. If Call-out is enabled, the SP calls to
report the failure.
Call Out (Call-Home)
The SP 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 environmental failures.
v
Restarts
To enable the call out feature, you need to do the following:
v
Have a modem connected to serial port 1 or 2.
v
Set up the following using the SP Menus or Diagnostic Service Aids:
– Enable call out for the serial port where the modem is connected.
– Set up serial port line speed.
– Enter the modem configuration filename.
– Set up site specific parameters (i.e. phone numbers for call out, call out policy, etc).
v
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 SP 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.
Console Mirroring
Console mirroring allows a person on a local service terminal to monitor the SP activities of a remote user.
Console mirroring ends when the SP releases control of the serial ports to the system firmware.
