Goal

How to display HBA information and status

How to display the FC HBA device ports

Solution

The luxadm command can be used to display the path to the FC HBA device and the status of the connection.
For example:

# luxadm -e port
/devices/pci@5,700000/SUNW,qlc@0/fp@0,0:devctl                     CONNECTED
/devices/pci@4,600000/SUNW,qlc@0/fp@0,0:devctl                     CONNECTED
/devices/pci@3,700000/SUNW,qlc@0/fp@0,0:devctl                     NOT CONNECTED
/devices/pci@3,700000/SUNW,qlc@0,1/fp@0,0:devctl                  CONNECTED
/devices/pci@4,600000/SUNW,qlc@0,1/fp@0,0:devctl                  NOT CONNECTED
/devices/pci@5,700000/SUNW,qlc@0,1/fp@0,0:devctl                  CONNECTED
/devices/pci@7,700000/SUNW,qlc@0/fp@0,0:devctl                     CONNECTED
/devices/pci@7,700000/SUNW,qlc@0,1/fp@0,0:devctl                  NOT CONNECTED

1. CONNECTED means that there is a FC device connected on the HBA controller port

2. NOT CONNECTED means that there is no FC device connected on the HBA controller port

3. /devices/pci@7,700000/SUNW,qlc@0,1/fp@0,0:devctl is the physical pathname to the host controller port.

4. /devices/pci@4,600000/SUNW,qlc@0,1/fp@0,0:devctl - "pci" indicates the PCI bus to which the HBA is plugged in

5. /devices/pci@4,600000/SUNW,qlc@0,1/fp@0,0:devctl - "@4" is the instance of the PCI controller.

6. /devices/pci@4,600000/SUNW,qlc@0,1/fp@0,0:devctl - "SUNW,qlc" refers to the HBA device driver.
( "qlc" is the FC Solaris Leadville driver for Oracle-branded Qlogic HBAs )

    In the case of Oracle branded HBAs, the following device drivers are available:
       qlc    - Qlogic hba from Sun/Oracle
       emlxs - Emulex hba from Sun/Oracle

    For Non Oracle HBAs:
       lpfc - emulex from Emulex
       qla - qlogic hba from Qlogic
       qlt - COMSTAR driver for a target QLogic 4G HBA (Used with ACSLS logical libraries)

7. /devices/pci@4,600000/SUNW,qlc @ 0,1/fp@0,0:devctl - "0,1" points to the second controller in the same HBA and in same PCI Bus (i.e., in a 2-port HBA);
                                    - same as /devices/pci@4,600000/SUNW,qlc@0/fp@0,0:devctl

8. /devices/pci@4,600000/SUNW,qlc@0,1/fp@0,0:devctl - "fp" is the FC port controller's device driver
