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 per-
     forms 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.
