NAME

edd- event detector daemon

SYNOPSIS

edd

-a

-d

CAUTION

Do not execute this program manually. It is automatically invoked by the SSP startup script and periodically monitored for restart.

DESCRIPTION

edd is a key component of the Sun Enterprise 10000 system's RAS features. When executed with no options, it checks the edd.emc(4) configuration file to determine which event-detection scripts it should use in monitoring the system. Then, if it detects one of those events for which it is checking, edd uses the edd.erc(4) configuration file to determine whether to take action and, if so, what action to take. If appropriate, it then executes the specified Response Action Script.

Each Sun Enterprise 10000 system has one edd.emc(4) file, one edd.erc(4) file for global events (those that affect the entire system), and one edd.erc(4) file for each domain. The locations of these files are shown below in FILES. Refer to edd.emc(4) for a list of the events being monitored and edd.erc(4) for a list of the actions to be taken if any of those events occur.

You can prevent edd from responding to some events by editing either the edd.emc(4) file to disable the uploading of certain event-detection scripts, or editing the edd.erc file to prevent edd from executing certain Response Action Scripts.

In case of conflict, the options to edd override any actions specified in the edd.emc(4) and edd.erc(4) files.

Note for Service Providers: When edd produces a dumpfile due to an arbstop or recordstop in a domain that is part of an InterDomain Network (IDN), the dumpfile provides information about all domains in that IDN. For an arbstop, edd also saves the BBSRAM information for the boot processors of the IDN domains in a separate file.

OPTIONS

The following options are supported:

-a: Take no action; do not invoke any Response Action Scripts.
-d: Do not upload event monitoring scripts to the active control board.

SIGNALS

SIGHUP: Reread the event response configuration files. This signal does not affect response actions for previously received events.

FILES

The following files are supported:

$SSPVAR/etc/platform_name/edd.emc

$SSPVAR/etc/platform_name/edd.erc
