NAME
       dgsvc_d, dgsvc_mid, dgsvc_timd, dgsvc_pwd, dgsvc_inetd, dgsvc_cld -
       Data General AV/Alert service daemons

SYNOPSIS
       /usr/sbin/dgsvc_d [ -u updatetime ]
       /usr/sbin/dgsvc_mid [ line ]
       /usr/sbin/dgsvc_timd
       /usr/sbin/dgsvc_pwd
       /usr/sbin/dgsvc_inetd
       /usr/sbin/dgsvc_cld

   where
       updatetime
              Number of minutes, must be 5 or greater.

       line   Device name, must start with /dev/tty. If this argument is
              present it must be last on the command line.

DESCRIPTION
       dgsvc_d, the Data General service daemon, provides a central location
       for the management of system error information obtained from DG/UX
       device drivers.

       dgsvc_mid, the Data General machine initiated callout daemon, directs
       error information to the appropriate Data General Customer Support
       Center.  This daemon expects a Hayes-compatible modem to be connected
       to the specified tty line.  The argument line is defined in the file
       /etc/dgux.params and is used by /sbin/rc.init during normal start up.
       The default value for line in /etc/dgux.params is /dev/tty00.  This
       is also the default if no argument is supplied.

       dgsvc_inetd, a Data General network forwarding daemon, receives and
       directs error information via a Unix domain socket.  This daemon
       requires the tcpip package be installed.  The port number assigned
       for the service deamon to use is defined in /etc/services.

       dgsvc_cld, a Data General network forwarding daemon, receives and
       directs error information via the RPC mechanism.  This daemon
       requires the tcpip and ONC packages be installed.  The dgsvc_cld
       network forwarding daemon will run on any system with a modem.  It
       can be found by other systems by using the RPC broadcast mechanism,
       without operator assistance.

       dgsvc_timd, a child process of dgsvc_d, is used to timestamp service
       daemon activity.

       dgsvc_pwd, the Data General service information daemon, monitors
       service information and reports changes to the appropriate Data
       General Customer Support Center.

       All these daemons are started at user run level 1 or greater with the
       exception of dgsvc_inetd, which will start at run level 2 or greater,
       and

dgsvc_d(1M)                      DG/UX R4.11                     dgsvc_d(1M)


        dgsvc_cld, which will start at run level3.  Logging and hardware
       error management are provided by dgsvc_d unconditionally.  The DG/UX
       device drivers provide a special interface to dgsvc_d by which
       messages may be passed from the kernel to the service daemon.  Upon
       receipt of a message from a device driver, the service daemon formats
       and logs the message in /var/adm/dgsvcmgr/dgsvcd_log.  In addition to
       device driver messages, dgsvc_d posts its own error notifications in
       /var/adm/dgsvcmgr/dgsvcd_log.

       The primary Data General proprietary service feature supported by
       dgsvc_d is machine-initiated callout of hardware errors to a Data
       General Customer Support Center.  Proprietary service features are
       available only to Data General customers who have signed the
       appropriate service agreement.

       Options are:

       -u    The amount of time to wait in between updating the time
             stamp file.

       line  Specifies a device name to use as a communication line.


EXAMPLES
       The following is an example of a message fielded by dgsvc_d and
       written to /var/adm/dgsvcmgr/dgsvcd_log:

       (5-27-92 11:16:55) AV/Alert System: Insertion of disk array disk
        at position B0 (disk array adapter at address ffff1000)
       (5-27-92 11:16:55) Detail: 60000302 00060102 00000000 00000000
       (5-27-92 11:16:55)         00000000 00000000 00000000 00000000

       This message indicates that a disk unit has been inserted into the
       High Availability Disk Array subsystem chassis.

FILES
       /var/adm/dgsvcmgr/rbos.config  The configuration file for the system.

       /var/adm/dgsvcmgr/dgsvcd_log   The log file for dgsvc_d.

       /etc/services                  Port number assignment file.

       /dev/fru/*                     Character special files through                                                 which DG/UX device drivers provide                                              messages to dgsvc_d.

       /dev/fe                        The FE (Field Engineering) support                                              driver character special file                                                   which provides proprietary service                                              information to the service daemon.

DIAGNOSTICS
       dgsvc_d exits with a status of 0 if it is unable to open any
       character special files in /dev/fru.  dgsvc_d should never exit with
       a non-zero status.
