hwmgr(8)							      hwmgr(8)

NAME
       hwmgr,  hardware	 - Command line interface for managing hardware compo‐
       nents

SYNOPSIS
       /sbin/hwmgr [-help] command [subsystem] [parameters]

OPTIONS
       The following options are used with many of the commands. Other options
       are  unique to the individual commands and are documented with the com‐
       mands.  Perform the operation on every  member  of  the	cluster.  This
       option  is valid only when the system is a cluster member.  Perform the
       operation on the specified cluster member. This option  is  valid  only
       when  the  system  is a cluster member.	Display extended details where
       they are provided.  Causes the command output to	 be  truncated	at  80
       columns.	  See	ENVIRONMENT   VARIABLES	  for  a  description  of  the
       HWMGR_NOWRAP variable.  Provide detailed information about  the	return
       status  of  this command.  You must not abbreviate the -verbose option.
       To make the verbose operation default, define the environment  variable
       HWMGR_VERBOSE = TRUE as described in ENVIRONMENT VARIABLES.

DESCRIPTION
       The  hwmgr  command  enables  you to manage hardware components and the
       software subsystems that maintain information about the	components.  A
       hardware component can be a storage peripheral, such as a disk or tape,
       or a system component such as a CPU or a bus.

       You can use the hwmgr command on either	an  individual	system	or  on
       clustered systems to manage hardware, gather information on system sta‐
       tus, and diagnose problems. The hwmgr command  provides	the  following
       features:  Provides a wide range of hardware management functions under
       a single command.  Enables you to manage (to a small  extent)  hardware
       components  that	 are  not  currently connected to your system but were
       seen on a previous system boot.	Enables you to manage hardware	compo‐
       nents  that  are connected to multiple systems in the cluster.  Enables
       you to propagate a management request to multiple members of a cluster.

       The hwmgr command enables you to manage hardware components. The	 hwmgr
       commands	 are  organized into related groups and documented in the fol‐
       lowing reference pages: hwmgr(8) - The hwmgr command overview. It  also
       describes options for configuring the environment variable settings for
       the hwmgr command.  hwmgr_get(8) - Commands that enable you to  display
       and  set	 information  about the system and its hardware components and
       their attributes (or properties), such as the capacity of a  hard  disk
       or  the speed of a CPU.	hwmgr_view(8) - Commands that display informa‐
       tion about the status of the system and its  hardware  components.  The
       display	output	from  each  command organizes the data into a specific
       format.	hwmgr_show(8) - Commands that enable you to  display  informa‐
       tion  from  specific hardware subsystems.  hwmgr_ops(8) - Commands that
       enable you to perform administrative tasks on hardware components, such
       as  scanning  buses,  locating components, powering off components, and
       deleting components.

       You can abbreviate some hwmgr command options  and  parameters  to  the
       fewest unique characters.

       For  information	 on using the hwmgr command to hot-swap certain compo‐
       nents, see olar_intro(5) and the Managing Online Addition  and  Removal
       manual.

       You can run some hwmgr commands using the SysMan Menu, and also monitor
       component properties and attributes using the SysMan Station. You  must
       be  superuser  (root) to use the hwmgr command; however, you can assign
       root privileges by using the Division of Privileges (DOP) command.

ENVIRONMENT VARIABLES
       The hwmgr command provides a  set  of  environment  variable  settings,
       which you can set in your preferred environment configuration file such
       as your file as follows: Use this variable to set the location  of  the
       main   hwmgr   command	data   file.   The   default   path   name  is
       /etc/hwmgr/hwmgr.dat.  Use this variable to set debugging  on  or  off.
       The default value is FALSE (off).  Use this variable to set the display
       output to hexadecimal. The default value is FALSE  (off).   Causes  the
       command output to be truncated at 80 columns rather than wrapped.  (See
       the -nowrap option described in the  in	OPTIONS	 section.)   Use  this
       variable to set the hwmgr command to display verbose output by default.
       This option can also be specified using the -verbose option on the com‐
       mand line. The default value is FALSE (off).

       Use  the	 hwmgr	view environment command option to display the current
       values of the environment variables  as	follows:  #  /sbin/hwmgr  view
       environment  HWMGR_DATA_FILE  =	"/etc/hwmgr/hwmgr.dat"	HWMGR_DEBUG  =
       FALSE HWMGR_HEXINTS = FALSE HWMGR_NOWRAP = FALSE HWMGR_VERBOSE = FALSE

RESTRICTIONS
       The following notes and restrictions apply: When working on a  cluster,
       if you do not specify an optional member name the operation defaults to
       the local member. (Some command options require that you specify a mem‐
       ber  name.)   Currently the locate component -id command is implemented
       only for some SCSI disks, using the  disk's  activity  indicator	 light
       (LED).	The  following	operations  on the name subsystem are not sup‐
       ported by all drivers: reload name unconfigure name unload name

ERRORS
       The command returns an int with an errorno from <errno.h>.

FILES
       The format of the hardware management data files is  undocumented.  You
       must  never manually change the content of the data files or the system
       might not boot. Such problems might be unrecoverable, requiring a  com‐
       plete  rebuild of the system and of all application databases that rely
       on device naming (such as the Logical Storage Manager).	The executable
       image  The main data file The data file for the Fibre Channel subsystem
