SYNOPSIS

       hafs -h

       hafs [ -f  schema file ] [ -L  | -l  log file ] [ -v ]

       hafs -n [ -f  schema file ] [ -L  | -l  log file ] [ -v ]

       hafs -g [ -f  schema file ] [ -L  | -l  log file ] [ -v ]

DESCRIPTION

       The  hafs  program  is used to collect a pre-defined set of file system
       information from the local host. The collected information is  used  to
       update  a  local  RAP  database  or dumped to the standard output if -n
       option is selected.

       The set of information collected by hafs is defined in an ASCII  schema
       file   specified   by   the   -f  option  and  has  the  default  value
       schema/hafs.sch.  Each line in the  schema  file  represents  a  single
       attribute   and  my  have  one  or  more  values  associated  with  it.
       Attributes other than resource type and  version  number  are  used  to
       determine  the  type  of  information  to be reported by hafs.  A given
       pieces of information will not be collected or reported if the  associ-
       ated  attribute is commented out with # or remove from the schema file.
       Note that attributes resource type and version number are part of every
       schema  file and should not be removed or commented out.  A schema file
       will be rejected if one or more  essential attributes  are  missing  or
       the  value  associated  with  the version number does not match that of
       hafs.  hafs can be used to generate a fresh schema file  using  the  -g
       option.

       The  file  system  information  reported by hafs is defined in the file
       hafs.sch as follows:

       file system
              file system type name.

       free space (MB)
              free space in MB in this file system.

       mount point
              mount point for this file system.

       total space (MB)
              total space in MB in this file system.

       used space (MB)
              used space in MB in this file system.

OPTIONS

       -f schema file
              Specifies the full path for  the  schema  file  associated  with
              hafs.   When  -f  is  not  specified, the default schema file is
              hafs then any logging information will be printed on stdout  and
              stderr.

       -l log file
              Allows  you to specify the name of the file that hafs will write
              its log to. Only one of -L or -l may be specified - not both. If
              neither  -L or -l is specified in the arguments to hafs then any
              logging information will be printed on stdout and stderr.

       -n     Dump the collected information to the standard  output;  do  not
              update the local RAP database.

       -g     Generate  a  new  schema  file  for  hafs after renaming the old
              schema, if exists, to <name>.<date>.[1..]

       -h     Display a brief help message; ignore all other options.

       -v     Run in verbose mode.

EXAMPLES

       Collect file system information and dump the  result  to  the  standard
       output, do not update the local RAP data base:

                            hafs -n

       Collect file system information and update the local RAP data base:

                            hafs

DIAGNOSTICS

       Some  information  may  not  be available on all systems, configuration
       problems, hardware/software limitations.   Attributes  associated  with
       missing information are assigned the value not available.
