survd Daemon

Purpose

Controls the surveillance daemon.

Syntax

Controls Surveillance Parameters

survd [ -d Delay ] [ -h ]

Resets the Surveillance

survd -r

Description

The survd command enables a user with root authority to control the surveillance daemon. You can choose the frequency of the signals that the operating system sends to the bring-up microprocessor (BUMP), using the -d Delay flag. You can also choose the way the BUMP will reboot the system (hardware or software reboot) if it does not receive a signal from the operating system within the given delay. (The -h flag stands for hardware reboot required). Finally, you can decide to turn the surveillance off, using the -r flag.

The survd daemon works only on multiprocessor systems with Micro Channel I/O for AIX 5.1 and earlier. For IBM systems, this includes the IBM 7012 Model G Series, the IBM 7013 Model J Series, and the IBM 7015 Model R Seriesfor AIX 5.1 and earlier.

Attention: Do not use the kill command to stop the surveillance: in this case the BUMP would no longer receive signals from the daemon and would reboot the system.

Flags

Security

Access Control: Only the root user can run this command.

Examples

1. To set the signal period to 70 seconds, enter:

   survd -d 70

   Note that if no signal is received by the BUMP within 70 seconds, the BUMP will execute a software reboot, since the -h flag is not specified.

2. To turn the surveillance off, enter:

   survd -r
