Solution 1474002.1 : Display HBA Control Path's ( luxadm)

Applies to:

Sun StorageTek SL3000 Modular Library System - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.

Goal

Display HBA information and status

Fix

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 HBA


 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
