hwmgr_show(8)hwmgr_show(8)NAMEhwmgr_show - Displays information from kernel-based hardware subsystems
SYNOPSIS
/sbin/hwmgr show [component | fibre | name | scsi] [subsystem-specific-
options]
/sbin/hwmgr pathlist scsi
OPTIONS
Displays hardware component information from the hardware component
subsystem. This includes all hardware components, including those that
the system registered on previous boots, but are not currently con‐
nected to your system.
The show component command displays a FLAGS field as part of the
output. The FLAGS field is a series of characters that provide
information about the state of a hardware component. The fol‐
lowing characters are used: The component is currently regis‐
tered with hardware management. The component has device spe‐
cial files associated with it. The component has a clusterwide
unique name. The component has saved attributes associated with
it in the on-disk hardware database. This component has an
inconsistency in the hardware component database.
You can specify the following additional options with the hwmgr
show command to control the output: Shows all hardware compo‐
nents that are currently registered with hardware management.
Shows all hardware components that are not currently registered
with hardware management. These components were previously reg‐
istered. Shows all hardware components that are cluster shared.
A cluster shared hardware component is a hardware component that
has a name that is guaranteed to be unique anywhere in the clus‐
ter. Shows all hardware components that are NOT cluster shared.
See the -cshared option for a definition of cluster shared.
Shows all hardware components that have device special files
associated with them. Shows all hardware components that do not
have device special files associated with them. Shows all hard‐
ware components that have saved attributes. See the hwmgr get
command option for a description of saved attributes. Shows all
hardware components that do not have saved attributes. See the
hwmgr get command option for a description of saved attributes.
Shows all hardware components that have software inconsistencies
in the hardware component database. An inconsistency is a pos‐
sible internal error with the component database. Use the show
-full command option to obtain detailed information about possi‐
ble problems.
This command does not fix database inconsistencies; it only
detects inconsistencies. One possible fix might be to reboot
the system. Shows all hardware components with no software
inconsistencies. Shows detailed information about the hardware
component. Displays output from the show command option in an
alternate format. The tcl format is the only alternate format
supported in this release. Specifies a cluster member on which
you want to perform the hwmgr show operation. Specifies that
the operation be performed on every member of the cluster. This
option is valid only when the local system is a cluster member.
Specifies the hardware identifier (HWID) of the component on
which you want to perform the show operation.
If no member ID is specified and the -cluster option was not
used, the show operation defaults to all components on the local
system. Displays information from the Fibre Channel (emx) sub‐
system. When you enter the hwmgr show fibre command without any
options, the following information is returned for all adapters:
The hardware identifier for this Fibre Channel component. The
name and instance of the specified Fibre Channel component. Use
the hwmgr show name command to determine adapter names, such as
emx0. The current state of the adapter's link connection to the
fabric (switch), loop to the hub, or adjacent ports in the loop.
Possible states are as follows: up - The link is connected and
available for I/O. down - The link is not available. This
adapter has no visibility into the fabric or loop and cannot
transfer any I/O to storage devices. paused - The link is in a
temporary state between up and down. A link condition was
detected. If the link comes back quickly, it does not change to
the down state. The link type and mode, which is independent of
the fabric connection. The link can be one of the following
types: point-to-point - The adapter is connected directly to
another port. loop - The adapter is connected in a loop. Either
it is connected directly to an upstream port and a downstream
port, or the cable pair is plugged into a hub (switch), creating
a loop out of all ports connected to the hub. Whether the
adapter is logged into an F_PORT (switch port). This field can
either be attached or blank (null).
An attached state can exist under either point-to-point or loop
link types. Under point-to-point it indicates that the adapter
is directly plugged into a switch port (F_Port). Under loop it
indicates that at least one of the ports connected in the loop
is an F_Port. However, there might be several other loop ports
between the adapter and the F_Port that are in loop mode.
(Fabric loop attach from a host adapter is not supported in
Tru64 UNIX Version 5.1B). The SCSI bus name of the bus that is
supporting this connection. Use the hwmgr view hierarchy command
to determine the location of the bus in the system hardware
hierarchy. The model number and revision type of the Fibre
Channel device.
Specify the following additional options to control the output:
Specifies the hardware identifier (HWID) of a specific Fibre
Channel component such as a host bus adapter (HBA). Use the
hwmgr view hierarchy command to obtain a component's HWID.
Specifies a component name, such as adapter emx1. Use the hwmgr
show name command to determine adapter names, such as emx0.
Displays additional information for all Fibre Channel adapters.
This option provides the following information: Revisions:
driver 2.01 firmware 3.03A1 FC Address: 0x21300 TAR‐
GET: -1 WWPN/WWNN: 1000-0000-c922-2f6b
2000-0000-c922-2f6b
The additional information fields are defined as follows: Revi‐
sions: - The loaded versions of the driver software and compo‐
nent firmware. FC Address: - The component's Fibre Channel
device identifier (DID) address in hexadecimal. This address is
either self-determined in a loop topology or assigned by the
fabric in a point-to-point fabric configuration. TARGET: - A
field that is provided for backwards compatibility with output
from the retiring emxmgr command. A valid SCSI target ID is no
longer assigned to the host bus adapter; its value is always -1.
WWPN/WWNN: - The Fibre Channel worldwide port name and worldwide
node name. The combination of these values is the worldwide name
which is a 64-bit unique identifier assigned to a Fibre Channel
entity. (This identifier is similar to the concept of the MAC
address assigned to an Ethernet network adapter.) Displays the
port mapping information for all links in the fabric. This
option provides the same link state information that is dis‐
played when you use the hwmgr show fibre -id and hwmgr show
fibre -name commands. In addition, the following mapping infor‐
mation is displayed:
FC DID - A field that contains the same information the FC
Address, which is the device's Fibre Channel device identifier
(did) address in hexadecimal. TARGET - The SCSI target ID
assigned to this particular N_Port. A value of -1 indicates that
the remote port is a special fabric port that provides a fabric
service. A value of -2 indicates that this is a remote N_Port
that does not provide SCSI target mode service. This indicates
that the N_Port is probably another host bus adapter. WWPN -
The Fibre Channel worldwide port name. WWNN - The Fibre Channel
worldwide node name. lfd - A flags field providing the follow‐
ing port information: l - The adapter is logged in to the port
as a Fibre Channel device. f - The port is an F_Port (switch
port). d - The port is a fabric directory server. LSIT - A
flags field that provides the following SCSI information: L
(logged in) - The adapter is logged in to the port as FCP
(SCSI). S (suspended) - The FCP login is currently suspended.
I (initiator) - The port is an FCP (SCSI) initiator. T (target)
- The port is an FCP (SCSI) target. Specifies a cluster member
on which you want to perform the hwmgr show fibre operation.
Use the hwmgr view hierarchy and hwmgr show component commands
to display configuration information about the Fibre Channel
devices. Use the hwmgr get attribute and hwmgr set attribute
commands to return the attributes (device characteristics or
properties) associated with the Fibre Channel device. Displays
information from the name subsystem, which maintains an on-disk
database that preserves the names of most hardware components.
Typical names are pci0 (PCI bus) and tu3 (Tulip, a type of net‐
work card). Use the view hierarchy command option to obtain the
component type that is associated with a name.
This operation defaults to the local system if you do not spec‐
ify a cluster member. Specifies a cluster member on which to
perform the show operation. Displays information from the SCSI
subsystem, which maintains information about SCSI devices, and
does not include SCSI adapters. You can specify the following
options with the hwmgr show scsi command: Shows SCSI information
for only the component specified by the hardware component iden‐
tifier. Shows SCSI information for the component specified by
the SCSI device identifier (did). The did is a specific identi‐
fier used by the SCSI subsystem, and differs from the hardware
identifier (HWID). Shows SCSI entries with a path (valid or
stale) at the specified bus. A stale path occurs when a compo‐
nent that was previously seen at a path is no longer accessible
at that path. Shows SCSI entries at the specified target.
Shows SCSI entries at the specified lun (logical unit number).
Specifies a cluster member on which to perfom the show opera‐
tion. This operation defaults to the local system if no cluster
member identifier is specified. Specifies a SCSI device type,
such as disk or tape. SCSI device types are: disk, tape,
printer, processor; worm, cdrom, scanner, optical, changer,
raid, enclosure, unknown. Specifies that only SCSI components
with valid paths be displayed. If the system can access a compo‐
nent through a path, the path is valid. Specifies that only
SCSI components with stale paths be displayed. A path becomes
stale when a component that was previously seen at a path is no
longer accessible at that path. Specifies that the command out‐
put includes detailed information, if available. Identifies one
of the following PATH STATE conditions:
active
standby
failed
unknown
rad active
The -pathdetails option only works with the -full option. Works
with the scsi subsystem to give a count of the number of active,
standby, inactive, or failed paths on a system in one line. You
can specify the following additional options with the pathlist
scsi command to control the output (see the show scsi command
for information about these options):
-id
-did
-bus
-target
-lun
-type
DESCRIPTION
The commands described in this reference page are a subset of the com‐
mand options available from the hwmgr utility. Refer to hwmgr(8) for
more information.
Hardware subsystems maintain on-disk databases that contain information
about hardware components. You use the hwmgr show command options to
display information from the following hardware subsystems: The compo‐
nent subsystem maintains information on all hardware components speci‐
fied in the /etc/dec_hwc_ldb and /etc/dec_hwc_cdb binary databases.
These databases contain information on most devices that are connected
to the system. The fibre subsystem maintains information on all fibre
channel components specified in the /etc/emx_db binary database. The
name subsystem maintains information on all hardware components in the
/etc/dec_hw_db binary database, often referred to as the hardware
topology. The database contains hardware name persistence information
that is maintained by the kernel driver framework and includes informa‐
tion about most buses, controllers, and devices. The scsi subsystem
maintains information on all SCSI devices in the /etc/dec_scsi_db
binary database.
When managing the system hardware, you typically use the show option to
obtain information on components that you need to manage. (For exam‐
ple, a component's HWID (hardware identifier) or name. You can then
specify this information as a command parameter with hwmgr operational
commands. Refer to the following reference pages for information on
related commands: hwmgr_view(8) - Describes commands that enable you to
display information about the status of the system and its hardware
components. hwmgr_get(8) - Describes commands that enable you to dis‐
play (get) or configure (set) component attributes such as the capacity
of a hard disk or the speed of a CPU. You can also display component
category names. hwmgr_ops(8) - Describes commands that enable you to
perform administrative tasks on hardware components, such as scanning
buses, locating components, powering off components, and deleting com‐
ponents.
See the Hardware Management manual for more information about compo‐
nents, device special files, and a definitive list of the supported
device names. This manual provides further examples of hwmgr command
usage and common procedures.
You can run some hwmgr commands directly from the SysMan Menu. You can
also monitor many properties and attributes of components by using the
SysMan Station GUI. See the System Administration manual for informa‐
tion about these interfaces.
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>.
EXAMPLES
