HP-ASRD(8)            HP Advanced Server Recovery Daemon            HP-ASRD(8)



NAME
       hp-asrd - HP Advanced Server Recovery Daemon

SYNOPSIS
       hp-asrd [OPTION]...

DESCRIPTION
       The  HP  Advanced Server Recovery Daemon provides a mechanism for auto-
       matically restarting your system in the event of an unrecoverable oper-
       ating  system  hang. hp-asrd makes use of the various hardware watchdog
       features provided across the HP ProLiant product line.

       By default, hp-asrd will automatically detect the  watchdog  mechanisms
       available  on  the system and select the one recommended by HP. hp-asrd
       will also, by default, make use of the ASR settings defined in the ROM-
       Based  Setup Utility (RBSU). These settings maybe overridden by modify-
       ing the initscript (/etc/init.d/hp-asrd).

       The HP ProLiant ROM will check a status bit on the ASM hardware to  see
       if  an  ASR event took place and will log a message to the IML as such.
       The message logged will be "ASR Detected by System ROM".

       Note: Prior to hp-health 8.5.0, ASR functionality was managed  directly
       by the health daemon.

OPTIONS
       The following is a list of features supported by  the  hpasmd  applica-
       tion:

       -p INTERVAL
              Polling Interval (seconds)

       -t TIMEOUT
              Timeout Interval (seconds)

       -m MODE
              Specify a watchdog usage mode. MODE can be one of the following:

              auto   The default. Probe for available modes in order of  pref-
                     erence.  The  order  of preference follows the same order
                     listed below.

              hpwdt  Use the /dev/watchdog interface if it is provided by  the
                     hpwdt driver. This device is only supported on iLO2/iLO3.

              iloraw Use the iLO2/iLO3 watchdog  via  raw  /dev/mem  accesses.
                     This  makes  use  of  the same underlying hardware as the
                     hpwdt driver, and should only be used if the hpwdt driver
                     is not available.

              ipmiwd Use  the /dev/watchdog interface if it is provided by the
                     ipmi_watchdog driver.

              devwd  Use the  /dev/watchdog  interface,  regardless  of  which
                     driver is providing it.

       -d     Debug mode, stay in foreground.

       -h     Display help information.
