DESCRIPTION
The InfiniBand hardware specific library /usr/lib/cfgadm/ib.so.1 pro‐
vides the functionality for administering its fabric through the
cfgadm(8) utility. cfgadm operates on attachment points. See cfgadm(8).
An InfiniBand (IB) device is enumerated by the IB nexus driver, ib(4D),
based on the services from the IB Device Manager (IBDM).
The IB nexus driver creates and initializes five types of child device
nodes:
o IB Port devices
o IB HCA service (HCA-SVC) devices
o IB Virtual Physical Point of Attachment (VPPA) devices
o I/O Controller (IOC)
o IB Pseudo devices
See ib(4D) for details on enumeration of IB Port, IB VPPA, and IB HCA-
SVC devices. For additional information on IBDM, see ibdm(4D). See
ib(5) for details on IB Pseudo devices.
For IB administration, two types of static attachment point are created
for the fabric administration as seen by the given host. There is one
static attachment point ib and all IB devices (either an IOC, Port,
VPPA, HCA-SVC, or a Pseudo device) in the fabric are represented as
dynamic attachment points based off of it. There is another static
attachment point for each Host Channel Adapter (HCA) in the host based
on its node Globally Unique Identifier (GUID) value.
Attachment points are named through ap_ids. There are two types of
ap_ids: logical and physical. The physical ap_id is based on the physi‐
cal path name. For the IB fabric it is /devices/ib:fabric. The logical
ap_id is a shorter, and has a more user friendly name.
The static ap_id for the IB fabric is ib. The IB devices are dynamic
attachment points and have no physical ap_id. The logical ap_id of an
IOC contains its GUID, ib::IOC-GUID. An example of an IOC ap_id is
ib::80020123456789a. The logical ap_id of a Pseudo device, see ib(5)
for details, is of the format ib::driver_name,unit-address. An example
of a pseudo ap_id would be ib::sdp,0 where "sdp" is the driver name and
"0" is its unit-address property. The logical ap_id of Port, VPPA and
HCA-SVC device contains its Partition Key (P_Key), Port GUID / Node
GUID and a communication service-name. The format of ap_id is as below:
Port device
ib::PORT_GUID,0,service-name
VPPA device
ib::PORT_GUID,P_Key,service-name
HCA-SVC device
ib::HCA_GUID,0,servicename
The Partition Key (P_Key) is 0 for Port and HCA-SVC devices. The P_Key
helps determine the partition to which this port belongs for a VPPA
device node. A port might have more than one P_Key. An example of a
VPPA device logical ap_id point is ib::80245678,ffff,ipib. The port-
GUID is 80245678, the P_Key is 0xffff, and the service name is ipib.
The service-name information is obtained from the file
/etc/driver/drv/ib.conf which contains service-name strings. The HCA's
logical ap_id contains its node GUID value, hca:HCA-GUID. An example is
hca:21346543210a987.
A listing of the IB attachment points includes information on all IB
devices (IOC, VPPA, HCA-SVC, Pseudo, and Port devices seen by the IBDM
and the IB nexus driver) in the fabric even if they are not seen by the
host and configured for use.
The following shows a listing of five IB devices (two IOC, one VPPA,
one Port, one HCA-SVC) and one HCA:
example# cfgadm -al
Ap_Id Type Receptacle Occupant Condition
hca:21346543210a987 IB-HCA connected configured ok
ib IB-FABRIC connected configured ok
ib::80020123456789a IB-IOC connected configured ok
ib::802abc9876543 IB-IOC connected unconfigured unknown
ib::80245678,ffff,ipib IB-VPPA connected configured ok
ib::12245678,0,nfs IB-PORT connected configured ok
ib::21346543,0,hnfs IB-HCA-SVC connected configured ok
ib::sdp,0 IB-PSEUDO connected configured ok
The ap_id ib::802abc9876543 shows an IOC device that is not yet config‐
ured by the host for use or had been previously offlined by an explicit
cfgadm -c unconfigure operation.
The distinction was made by the information displayed under the Condi‐
tion column. The IB device with a zero P_Key and HCA GUID is a HCA-SVC
device. Refer to cfgadm(8) for more information regarding listing
attachment points.
The receptacle state for attachment points have the following meanings:
connected
For an IOC/VPPA/Port/Pseudo/HCA-SVC device, connected implies that
it has been seen by the host. The device might not have been con‐
figured for use by Solaris.
For a HCA attachment point, connected implies that it has been con‐
figured and is in use.
All IB ap_ids are always shown as connected.
The occupant state for attachment points have the following meanings:
configured
The IB device, and the HCA ap_id, are configured and usable by
Solaris.
unconfigured
The IB device at the ap_id was explicitly offlined using cfgadm -c
unconfigure, was not successfully configured. This could be because
it was not successfully configured for use with Solaris (no driver,
or a device problem), or because it was never configured for use by
the IB nexus driver.
The unconfigured operation is not supported for the HCA attachment
point. The IB static apid, ib, is shown unconfigured if the system
has no IB hardware.
The attachment point conditions are:
failed
Not used.
failing
Not used.
ok
Normal state. Ready for use.
unknown
This state is only valid for IB device that have been probed by
IBDM but not yet configured for use by Solaris. It is also shown
for devices that have been explicitly offlined by a cfgadm -c
unconfigure operation. This condition does not apply to a HCA
attachment point.
unusable
Not used.
OPTIONS
The following options are supported:
-c function
The IB hardware specific library supports two generic commands
(functions). These commands are not supported on the static attach‐
ment points (that is, the HCA ap_ids and the IB static ib ap_id).
The following generic commands are supported:
configure
Configure the IB device to be used by Solaris.
unconfigure
Unconfigure the IB device. If successful, cfgadm reports the
condition of this ap_id as unknown.
-f
Not supported.
-h ap_id
Obtain IB specific help for an IB attachment point.
-l
List the state and condition of IB attachment points. The -l option
works as described in cfgadm(8).
When paired with the -a option, displays the dynamic attachment
points as well (IOC, VPPA, Port, Pseudo, and HCA-SVC devices).
When paired with -v option, displays verbose data about the ap_ids.
For an IOC, the Info field in the
cfgadm -avl
output displays the following information: VendorID, IOCDeviceID,
DeviceVersion, SubsystemVendorID, SubsystemID, Class, Subclass,
Protocol, ProtocolVersion and IDString from the IOCControllerPro‐
file. If the ID string isn't provided then nothing is displayed in
its place. These fields are defined in the InfiniBand Specification
Volume 1 (https://www.infinibandta.org).
For a VPPA, Port, or HCA-SVC device the Info field in the cfgadm
-lav display shows the service name information to which this
device is bound. If no such information exists, nothing is dis‐
played.
For a Pseudo device cfgadm -alv displays the driver name and its
unit-address information. For a HCA the verbose listing displays
the VendorID, ProductID of the HCA, number of ports it has, and the
PortGUID value of its ports. See EXAMPLES.
-o hardware_option
This option is not currently defined.
-s listing_option
Attachment points of class ib can be listed by using the select
sub-option. Refer to the cfgadm(8) man page for more information.
-x hardware_function
Perform a hardware specific function. Note that the name can not be
more than 4 characters long.
The following hardware specific functions are supported:
add_service -ocomm=[port|vppa|hca_svc],service=name
This hardware specific function is supported on the static IB
attachment point. It can be used to add a new service to
/etc/driver/drv/ib.conf file and to update the ib(4D) driver.
You must use the service=name option to indicate the new ser‐
vice to be added. You must use the option
comm=[port|vppa|hca_svc] option to add the name service to
either port-svc-list or to the hca-svc-list in the
/etc/driver/drv/ib.conf file. See EXAMPLES.
delete_service -ocomm=[port|vppa|hca_svc],service=name
This hardware specific function is supported on the static IB
attachment point only. It can be used to delete an existing
service from the /etc/driver/drv/ib.conf file and also from the
ib(4D) driver's database. You must use the service=name option
to indicate which service to delete. You must use the
comm=[port|vppa|hca_svc] option to delete this service from the
port-svc-list, vppa-svc-list, or vppa-svc-list of the
/etc/driver/drv/ib.conf file. See EXAMPLES.
list_clients
Supported on HCA attachment points. Displays all the kernel IB
clients using this HCA. It also displays the respective ap_ids
of these kernel IB clients and if they have opened an alternate
HCA device. See EXAMPLES.
.
If a given kernel IB client does not have a valid ap_id then a
- is displayed in that column.
list_services
This hardware specific function is supported on the static IB
attachment point only. It lists all the Port and VPPA services
as read from the drv file. See EXAMPLES.
unconfig_clients
This hardware specific function is supported on the static HCA
attachment point only. It can be used to unconfigure all IB
kernel clients of this given HCA. Only IB kernel clients that
do not have an alternate HCA are unconfigured. See EXAMPLES.
update_pkey_tbls
Supported on the static ib attachment point. Updates the PKEY
information inside IBTL. IBTL re-reads the P_Key tables for all
the ports on each HCA present on the host.
See ibtl(4D).
EXAMPLES
Example 1 Listing the State and Condition of IB Devices
The following command lists the state and condition of IB devices on
the system. It only shows the static attachment points.
example# cfgadm

You can obtain more user-friendly output if you specify these following
cfgadm class and field selection options: -s
"select=class(ib),cols=ap_id:info"
The following command displays only IB ap_ids. The output only includes
the ap_id and Information fields.
# cfgadm -al -s "cols=ap_id:info" ib::80245678,ffff,ipib
Ap_Id Information
ib::80245678,ffff,ipib ipib
Example 3 Unconfiguring an Existing IB IOC
The following command unconfigures the IB IOC attached to
ib::80020123456789a, then displays the status of the ap_id:
# cfgadm -c unconfigure ib::80020123456789a
Unconfigure the device: /devices/ib:fabric::80020123456789a
This operation will suspend activity on the IB device
Continue (yes/no)?
Enter: y
