The InfiniBand hardware specific library /usr/lib/cfgadm/ib.so.1 provides the functionality for administering its fabric through the cfgadm(1M) utility. cfgadm operates on attachment points. See cfgadm(1M).
An InfiniBand (IB) device is enumerated by the IB nexus driver, ib(7D), based on the services from the IB Device Manager (IBDM).
The IB nexus driver creates and initializes five types of child device nodes:
IB Port devices
IB HCA service (HCA-SVC) devices
IB Virtual Physical Point of Attachment (VPPA) devices
I/O Controller (IOC)
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 physical 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(4) 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:
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 configured 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 Condition column. The IB device with a zero P_Key and HCA GUID is a HCA-SVC device. Refer to cfgadm(1M) for more information regarding listing attachment points.
The receptacle state for attachment points have the following meanings:
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 configured for use by Solaris.
For a HCA attachment point, connected implies that it has been configured and is in use.
All IB ap_ids are always shown as connected.
The occupant state for attachment points have the following meanings:
The IB device, and the HCA ap_id, are configured and usable by Solaris.
The IB device at the ap_id was explicitly offlined using cfgadm –c unconfigure, was not successfully configured. This could be because it wasn not successfully configuref 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:
Normal state. Ready for use.
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.
The following options are supported:
The IB hardware specific library supports two generic commands (functions). These commands are not supported on the static attachment points (that is, the HCA ap_ids and the IB static ib ap_id).
The following generic commands are supported:
Configure the IB device to be used by Solaris.
Unconfigure the IB device. If successful, cfgadm reports the condition of this ap_id as unknown.
Obtain IB specific help for an IB attachment point.
List the state and condition of IB attachment points. The –l option works as described in cfgadm(1M).
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
output displays the following information: VendorID, IOCDeviceID, DeviceVersion, SubsystemVendorID, SubsystemID, Class, Subclass, Protocol, ProtocolVersion and IDString from the IOCControllerProfile. If the ID string isn't provided then nothing is displayed in its place. These fields are defined in the InfiniBand Specification Volume 1 (http://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 displayed.
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.
This option is not currently defined.
Attachment points of class ib can be listed by using the select sub-option. Refer to the cfgadm(1M) man page for more information.
Perform a hardware specific function. Note that the name can not be more than 4 characters long.
The following hardware specific functions are supported:
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(7D) driver.
You must use the service=name option to indicate the new service 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.
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(7D) driver's data base. 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.
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.
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 /etc/driver/drv/ib.conf file. See EXAMPLES.
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.
This hardware specific function is supported on static ib attachment point and the IOC attachment points. For the ib APID, this function updates properties of all the IOC device nodes. For the IOC APID, this function updates the properties of specified IOC device node. This command updates the port-list, port-entries, service-id, and service-name IOC node properties .
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.
The following command lists the state and condition of IB devices on the system. It only shows the static attachment points.
example# cfgadm hca:21346543210a987 IB-HCA connected configured ok ib IB-FABRIC connected configured ok
The –a option lists all attachment points. The following example uses the –a option and lists all attachment points:
