Site Restart

A site restart is a hot restart of the entire system. All data of boot processes are reset to their original values from the previously loaded system image and the system enters its start-up phase again. As C_INIT restarts, sysadm.ini is reexecuted. Any calls to start restartable processes in the sysadm.ini file are ignored for a site restart because all direct restartable processes are automatically restarted by the system after the sysadm.ini file has been read.

When the system is restarted, previously mounted disks are not automatically remounted. To resolve this issue, ensure that the disks are mounted in the sysadm.ini file, or create a hot restartable process that will automatically mount the disks.

A site restart can be invoked automatically by the Hot Restart Controller, according to the tunable parameters that define the system's restart policy. For more information, see "Tunable Parameters".

To invoke a site restart programmatically, use the sysShutdown(2K) function call with the -i 1 arguments:

int sysShutdown (int argc, char** argv)

To provoke a site restart from the C_INIT command-line console, use the command shutdown -i 1 or restart(1M) command.
