NAME
cfgadm_fp - driver specific commands for cfgadm
SYNOPSIS
/usr/sbin/cfgadm [-f] [-n | -y] [-v] [-o hardware_options]
-c function ap_id [ap_id]
/usr/sbin/cfgadm [-v] [-a] [-s listing_options]
[-o hardware_options] [-l [ap_id]]
/usr/sbin/cfgadm [-v] [-o hardware_options] -h [ap_id]
DESCRIPTION
The fp port driver plug-in /usr/lib/cfgadm/fp.so.1 provides the func‐
tionality for Fibre Channel Fabric device node management through
cfgadm(8). cfgadm operates on attachment points. Attachment points are
locations in the system where hardware resources can be dynamically
reconfigured. Refer to cfgadm(8) for additional details on attachment
points.
For Fibre Channel Fabric device node management, each fp port node is
represented by an attachment point in the device tree. In addition,
each Fibre Channel device is represented by a dynamic attachment point.
Attachment points are named through ap_ids. Two types of ap_ids are
defined: logical and physical. The physical ap_id is based on the phys‐
ical pathname. The logical ap_id is a shorter, more user-friendly name.
For fp port nodes, the logical ap_id is the corresponding disk con‐
troller number. For example, c0 is a typical logical ap_id.
Fibre Channel devices are named with a port World Wide Name (WWN). If a
disk device is connected to controller c0, its ap_id can be:
c0::50020f2300006077
where 50020f2300006077 identifies the port WWN of a specific Fibre
Channel device.
Each device on the Fibre Channel private loop port, Fabric port or pub‐
lic loop port is probed and made available to Solaris by default.
Devices connected to the Fibre Channel Fabric port or public loop port
can be made unavailable to Solaris by initiating an application or an
end user operation. The operation is similar to the hot unplugging of
devices by way of management user interfaces. Applications or users can
use the /usr/lib/cfgadm/fp.so.1 library to enable libcfgadm to provide
interfaces to accomplish this task.
The list of currently connected Fabric devices is generated in the form
of the attachment point.
A simple listing of attachment points in the system includes attachment
points at fp port nodes but not Fibre Channel devices. The following
example uses the -a flag to the list option (-l) to list Fibre Channel
devices:
# cfgadm -l
Ap_Id Type Receptacle Occupant Condition
c0 fc-fabric connected configured unknown
c1 fc-private connected configured unknown
c2 fc-pt_to_pt connected configured unknown
c3 fc connected unconfigured unknown
sysctrl0:slot0 cpu/mem connected configured ok
sysctrl0:slot1 sbus-upa connected configured ok
The following example lists Fibre Channel devices connected to fp
ports.
# cfgadm -al
Ap_Id Type Receptacle Occupant Condition
c0 fc-fabric connected configured unknown
c0::50020f2300006077 disk connected configured unknown
c0::50020f23000063a9 disk connected configured unknown
c0::50020f2300005f24 disk connected configured unknown
c0::50020f2300006107 disk connected configured unknown
c1 fc-private connected configured unknown
c1::220000203708b69c disk connected configured unknown
c1::220000203708ba7d disk connected configured unknown
c1::220000203708b8d4 disk connected configured unknown
c1::220000203708b9b2 disk connected configured unknown
c2 fc-pt_to_pt connected configured unknown
c2::500104f000937528 tape connected configured unknown
c3 fc connected unconfigured unknown
sysctrl0:slot0 cpu/mem connected configured ok
sysctrl0:slot1 sbus-upa connected configured ok
In this example, the fc-fabric type of ap_id c0 indicates that the fp
port is connected to Fabric. For an fp port with a Fabric-related type
such as fc-fabric and fc-public, device node creation happens by
default at the boot time and can be managed by the cfgadm configure and
unconfigure operations. The fc-private type of ap_id c1 indicates that
fp port is connected to private-loop and device node creation happens
by default as well. The fc-pt_to_pt type of ap_id c2 indicates that the
fp port is directly connected to another N_port and device node cre‐
ation also happens by default. The fc type of ap_id c3 indicates that
nothing is attached to fp port c2. The Type field of a Fibre Channel
device ap_id shows the SCSI device type of LUN 0 in the device.
A Fibre Channel device with multiple FCP SCSI LUNs is configured into
Solaris and each FCP SCSI LUN is available as a Solaris device. Suppose
that ap_ids c0::50020f2300006077 and c0::50020f23000063a9 represent
Fibre Channel devices with multiple FCP SCSI LUNs.
The following example shows how to list ap_ids with FCP SCSI LUN
information:
# cfgadm -al -o show_SCSI_LUN
Ap_Id Type Receptacle Occupant Condition
c0 fc-fabric connected configured unknown
c0::50020f2300006077,0 disk connected configured unknown
c0::50020f2300006077,1 disk connected configured unknown
c0::50020f2300006077,2 disk connected configured unknown
c0::50020f2300006077,3 disk connected configured unknown
c0::50020f23000063a9,0 disk connected configured unknown
c0::50020f23000063a9,1 disk connected configured unknown
c0::50020f23000063a9,2 disk connected configured unknown
c0::50020f23000063a9,3 disk connected configured unknown
c0::50020f2300005f24,0 disk connected unconfigured unknown
c0::50020f2300005f24,1 disk connected unconfigured unknown
c0::50020f2300006107,0 disk connected unconfigured unknown
c0::50020f2300006107,1 disk connected unconfigured unknown
c1 fc-private connected configured unknown
c1::220000203708b69c,0 disk connected configured unknown
c1::220000203708ba7d,0 disk connected configured unknown
c1::220000203708b8d4,0 disk connected configured unknown
c1::220000203708b9b2,0 disk connected configured unknown
c2 fc-pt_to_pt connected configured unknown
c2::500104f000937528,0 tape connected configured unknown
c3 fc connected unconfigured unknown
In this example, the ap_id c0::50020f2300006077,0 identifies the FCP
SCSI LUN 0 of the Fibre Channel device which is represented by port WWN
50020f2300006077. The Fibre Channel device is reported to have 4 FCP
SCSI LUNs and they are all configured. 4 FCP SCSI LUN level ap_ids
associated with port WWN 50020f2300006077 are listed. The listing also
displays FCP SCSI LUNs for unconfigured Fibre Channel devices. The
Fibre Channel device represented by c0::50020f2300005f24 is reported to
have two FCP SCSI LUNs. The configure operation on c0::50020f2300005f24
creates two Solaris devices. The Type field of FCP SCSI LUN level
ap_ids show the SCSI device type of each LUN. When a Fibre Channel
device has different device type LUNs, the Type field reflects that.
The receptacle and occupant state for attachment points at the fp port
have the following meanings:
configured
One or more devices configured on the fp port
connected
fp port active
disconnected
fp port quiesced (IO activity is suspended)
empty
Not applicable
unconfigured
No devices configured on the fp port
The state for individual Fibre Channel devices on an fp port:
configured
Device is configured into Solaris and is available for use
connected
fp port to which the device is connected to is active
disconnected
fp port to which the device is attached is quiesced
unconfigured
Device is available to be configured
The condition field for attachment points at the fp port has the fol‐
lowing meanings:
failed
An error condition has prevented the fp port from being able to
detect the presence or type of a Fibre Channel connection.
The condition field for individual Fibre Channel devices on an fp port
has the following meanings:
failed
An error is encountered while probing a device on Fabric.
failing
A device was configured on a host and its state as seen by Solaris
appears to be normal (i.e., online) but it is either not currently
present or visible in the fabric or its presence could not be veri‐
fied due to an error condition on the local port through which the
device was configured.
unusable
A device has been configured on the host, but is currently offline
or failed.
The unknown condition indicates that probing a device on Fabric com‐
pleted without an error and the device state within Solaris host is
normal if the device was configured previously. The internal condition
of the device cannot be guaranteed.
OPTIONS
cfgadm defines several types of operations in addition to listing (-l).
These operations include invoking configuration state changes and
obtaining configuration administration help messages (-h).
The following options are supported:
-c function
The following generic commands are defined for the fp-transport-
specific library:
For Fibre Channel device attachment points on the fc-fabric type fp
port attachment point, the following configuration state change
operations are supported:
configure
Configure a connected Fibre Channel Fabric device to a host.
When a Fibre Channel device is listed as an unknown type in the
output of the list operation the device might not be config‐
urable. No attempt is made to configure devices with unknown
types. The force option (-f) can be used to force the fp port
driver plug-in to make an attempt to configure any devices. Any
errors in the process are reported. By default, each FCP SCSI
LUN that is discovered on a Fibre channel Fabric device is con‐
figured. However, FCP SCSI LUNs that are specified in the
"pwwn-lun-blacklist" property in the fp.conf file will remain
unconfigured. The FCP SCSI LUN level listing reflects the state
of such FCP SCSI LUNs. They stay in the "unconfigured" state
after reboot or Solaris Dynamic Reconfiguration on the con‐
troller that they are connected through. Refer to fp(4D) for
additional details on the "pwwn-lun-blacklist" property.
unconfigure
Unconfigure a Fibre Channel Fabric device from a host. This
device stays unconfigured until the next reboot or Solaris
Dynamic Reconfiguration on the controller that the device is
connected, at which time all fabric devices are automatically
enumerated.
For Fibre Channel private loop devices and N_Port point-to-point
devices, the configure command returns success without doing any
operation. The unconfigure command is not supported on the private
loop devices and N_Port point-to-point devices. The private loop
devices and N_Port point-to-point devices are configured by Solaris
Fibre Channel drivers by default and are not managed through end
user- or application-initiated operations. The pwwn-lun-blacklist
property in the fp.conf file is applied to the private loop device
and N_Port point-to-point device in the same way it is applied to a
Fabric device.
-f
Force the configure change state operation to occur irrespective of
the condition or type. Refer to the above description of the con‐
figure change state operation.
-h ap_id
Obtain fp—transport-specific help. Specify any fp attachment point.
-o hardware_options
The following hardware options are supported.
show_SCSI_LUN
Lists ap_ids associated with each FCP SCSI LUN for discovered
Fibre Channel devices when specified with the list option -al.
Refer to the previously mentioned description and example of
FCP SCSI LUN level listing. Device node creation is not sup‐
ported on the FCP SCSI LUN level. See NOTES.
When a Fibre Channel device has multiple FCP SCSI LUNs configured
and any Solaris device associated with its FCP SCSI LUN is in the
unusable condition, the whole Fibre Channel device is reported as
unusable. The following option with the -c unconfigure command
removes only Solaris devices with the unusable condition for a
Fibre Channel device.
unusable_SCSI_LUN
For unconfigure operation, any offlined device nodes for a tar‐
get device is removed.
-s listing_options
Refer to cfgadm(8) for usage information.
-t ap_id
No test commands are available at present.
-x hardware_function
No hardware specific functions are available at present.
All other options have the same meaning as defined in the cfgadm(8) man
page.

NOTES
For devices with unknown or no SCSI device type (for example, a Fibre
Channel Host Bus Adapter), the configure operation might not be appli‐
cable.
The configure and unconfigure commands operate on the Fibre Channel
device level which is represented by port WWN ap_id. If a Fibre Channel
device has multiple FCP SCSI LUNs configured, the configure command on
the associated port WWN ap_id results in creating a Solaris device for
each FCP SCSI LUN unless it is specified in the "pwwn-lun-blacklist"
property in the fp.conf file. The unconfigure command removes all
Solaris devices associated with the port WWN ap_id. The FCP SCSI LUN
level ap_id is not valid for the configure and unconfigure commands.
The deprecated show_FCP_dev option has been replaced by the new
show_SCSI_LUN option, and the deprecated unusable_FCP_dev option has
been replaced by the new unusable_SCSI_LUN option.
