ups_mond - HP PowerTrust Uninterruptible Power System monitor daemon SYNOPSIS
configfile] DESCRIPTION
When it detects a loss of AC power for a period of time exceeding a configured limit, ensures file system integrity by shutting down HP-UX. To do this, uses the device special files specified in its configuration file by default) to monitor the state of each HP PowerTrust Unin- terruptible Power System (UPS) attached to the system. Use the option to specify a configuration file other than See ups_conf(4) for a description of the configuration file format. By default, is locked into memory (see plock(2)). That is, is not swappable. Although extreme caution is required, you can make swappable if all swap disks are powered by an uninterruptible power system (assured to have power when the primary power source fails). To make swappable, use the option. When is forced to shutdown the system, it executes the command with real-time priority (default behavior). can be configured to execute command with a timeshare (non-real-time) priority by using the option. is started by (see init(1M)) by means of an entry in the file (see inittab(4)). The entry uses the option to automatically restart if is terminated by the command (see kill(1)). This entry should follow the entry: so that is started after the system logging daemon It should also be run with real-time priority to assure its execution (see rtprio(1)). logs messages, and when appropriate invokes using the option, or For each configured UPS, can be instructed (in to log messages only, with- out taking or action. See MSG_ONLY in ups_conf(4). By default performs the and actions. Note that when the shutdown is performed, UPSs that have lost AC line voltage will be turned off once the shutdown_timeout_mins time has expired (see ups_conf(4)). By default the system will power on when the AC line voltage is restored. The kill_after_shutdown line can be added to to tell the UPS not to come back up when AC line voltage is restored (see ups_conf(4)). uses the message logging facility to log these occurrences (see syslog(3C)). Messages are written to the console if is unable to send them to Critical messages (see DIAGNOSTICS section) are also sent to the console. RETURN VALUE
returns the following values: zero(0) Successful Completion non-zero Error encountered. See ERRORS below. EXAMPLES
The entry in should be similar to this: DIAGNOSTICS
Messages resulting from normal operation: Messages resulting in exit of daemon: Messages for which might be run (depends on UPS configuration): Messages for which might be run (depends on UPS configuration): The above messages are followed by the following message: Messages that are only logged (no action is taken): Messages relating to Timer Controlled Power On and Off: ERRORS
returns the following error values: encountered an incorrect parameter. Insufficient privileges. must be started by a superuser. was interrupted (terminated) by or See signal(2) and kill(1). one(1) For all other error conditions. FILES
