How to Enable Surveillance
Surveillance is implemented by the survd daemon. This daemon, when started, establishes
a heartbeat between AIX and SystemGuard. In case of an AIX hang, SystemGuard detects
it and reboots the system.
To implement the surveillance, do the following:
1. Enter:
survd –d {number of seconds}
This starts the survd daemon, thereby starting the surveillance. The
number of
seconds
determines the heartbeat delay time, where ten seconds is the minimum, and
the default is sixty seconds.
2. Carry out this step if you want a hardware reboot:
survd –h
(
–h
flag sets hardware reboot)
3. To turn off the surveillance, type the following command:
survd –r
Attention: If you issue the command
kill –9 <survd_proc_id>
, the system reboots
because SystemGuard thinks that AIX hung since it no longer receives a heartbeat.
How to Set Up the Dial-Out Feature
The dial-out feature can be implemented, either through SystemGuard or AIX.
Setting Up Dial-Out from SystemGuard
The dial-out feature is the automatic sending of certain errors to a service center. The
customer must set the Dial-Out Authorization flag. When the Physical Key is in the Normal
position, if a boot fails due to a POST error or boot device not found, a problem report is
sent to the remote service center.
The prerequisites for the dial-out feature are:
•
Remote Service Support flag enabled (1)
•
Remote authorization enabled (1)
•
Dial-out authorization enabled (1)
The dial-out feature uses the dial-out phone numbers listed in SystemGuard configuration.
To add or change phone numbers, do the following:
1. Enter the SystemGuard MAINTENANCE MENU.
2. Enter
8
from this menu to select the SET PARAMETERS menu.
3. Enter
3
from the SET PARAMETERS menu to select the PHONE NUMBERS menu.
4. Select your option, and enter the dial-out number or numbers. There are two service
center and customer hub numbers. These relate to primary (1) and secondary (2)
numbers.
