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]
The fp port driver plug-in /usr/lib/cfgadm/fp.so.1 provides the functionality for Fibre Channel Fabric device node management through
cfgadm(1M). cfgadm operates on attachment points. Attachment points are locations in the system where hardware resources can be dynamically
reconfigured. Refer to cfgadm(1M) 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 physical pathname. The logical ap_id is a shorter, more user-friendly
name. For fp port nodes, the logical ap_id is the corresponding disk controller 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 public 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 follow-
ing 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 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 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 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 hap-
pens by default as well. The fc type of ap_id c2 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. Sup-
pose 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 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 following meanings:
failed An error condition has prevented the fp port from being able to detect the presence or type of a Fibre Channel con-
nection.
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 verified due to an error condi-
tion 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 completed without an error and the device state within Solaris host is nor-
mal if the device was configured previously. The internal condition of the device cannot be guaranteed.
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 configurable. 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. See NOTES.
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 automati-
cally enumerated. The default behavior may be changed through the use of the "manual_configuration_only" property in
the fp.conf file. If the property is set, the device remains unconfigured after reboot. Refer to fp(7D) for additional
details on the "manual_configuration_only" property.
For Fibre Channel private loop devices, the configure command returns success without doing any operation. The unconfigure command is
not supported on the private loop devices. The private loop devices are configured by Solaris Fibre Channel drivers by default and are
not managed through end user- or application-initiated operations.
-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 supported on the FCP SCSI LUN level. See NOTES.
All Fibre Channel devices are available to Solaris by default. Enabling only a subset of Fabric devices available to Solaris by default
can be accomplished by setting the property "manual_configuration_only" in /kernel/drv/fp.conf file. When "manual_configuration_only"
in fp.conf is set, all Fabric devices are not available to Solaris unless an application or an end user had previously requested the
device be configured into Solaris. The configure state-change command makes the device available to Solaris. After a successful config-
ure operation on a Fabric device, the associated links are added to the /dev namespace. The unconfigure state-change command makes a
device unavailable to Solaris.
When a Fibre Channel Fabric device is configured successfully to a host using the -c configure operation, its physical ap_id is stored
in a repository. When a Fibre Channel Fabric device is unconfigured using the -c unconfigure operation, its physical ap_id is deleted
from the same repository. All fabric devices are automatically enumerated by default and the repository is used only if the fp.conf
"manual_configuration_only" property is set. Refer to fp(7D) for additional details on the "manual_configuration_only" property.
You can specify the following commands with the -c option to control the update behavior of the repository:
force_update For configure, the attachment point is unconditionally added to the repository; for unconfigure, the attachment point
is unconditionally deleted.
no_update No update is made to the repository regardless of the operation.
These options should not be used for normal configure and unconfigure operations. See WARNINGS.
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 target device is removed.
-s listing_options
Refer to cfgadm(1M) 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(1M) man page.

WARNINGS
Do not use hardware-specific options for the repository update under normal configure/unconfigure operations. The hardware-specific options
are expected to be used when the node creation of a Fabric device fails at boot time and the error condition is considered to be permanent.
The unconfigure command with force_update hardware-specific option unconditionally removes the attachment point of a failing Fabric device
from the repository.
For devices with unknown or no SCSI device type (for example, a Fibre Channel Host Bus Adapter), the configure operation might not be
applicable.
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. 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.
The cfgadm_fp service is managed by the service management facility, smf(5), under the service identifier:
svc:/system/device/fc-fabric:default
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser-
vice's status can be queried using the svcs(1) command.
No administrative actions on this service are required for Fabric device configuration once this service is started on boot time.
