hdelogger(1M)                                                 hdelogger(1M)


   NAME
         hdelogger - Hard Disk Error status report command and Log Daemon

   SYNOPSIS
         /usr/sbin/hdelogger [ -s ] [ -f ] [ -D maj min ]

   DESCRIPTION
         This command is part of the bad block handling utility.  It is
         executed automatically by the init in run levels 2, 3 and 4.

         The hdelogger command serves two purposes.  When run by the init
         process [process 1 - see init(1M)], this command performs the
         functions of the Hard Disk Error (HDE) Log Daemon.  These functions
         include providing summaries of outstanding errors during system
         startup and shutdown transitions, along with adding new errors to HDE
         Logs and giving the revised status summaries as errors are reported
         by hard disk drivers.  When run as the daemon, no options are used.

         When run as a normal command (process 1 is not its parent), this
         command provides on the spot reports of outstanding errors as
         recorded in the HDE Logs of equipped hard disks.  You must be the
         super-user to run the command this way.  The following options
         control report generation:

        -s     Specifies that summary reports are to be generated.  The
                summary report provides sufficient information for normal bad
                block handling operations.  This is the default.

        -f     Specifies that full reports are to be generated.  This is
                intended mainly for testing the bad block handling feature,
                but is available in case additional detail is needed for
                troubleshooting complicated problems.

        -D maj min
                Restricts the report generation to a specific hard disk.  If
                this option is omitted, reports will be generated for all
                equipped hard disks.
