Method used to check the WWN of Fibre Channel HBA ports when the device is running under common operating systems
Method used to check the WWN of Fibre Channel HBA ports when the device is running under various common operating systems: 1. Windows system In a Window system, you can use the management software provided by the Fibre Channel HBA card vendor to check the WWN of the fiber adapter. The WWN is as follows: Qlogic: SANsurfer Emulex: HBAnyware 2. SUSE Linux 9 Check /proc/scsi/qla2xxx/* and use adapter-port as a keyword to search for the WWN of Fibre Channel HBA ports. # cat /proc/scsi/qla2xxx/* | grep adapter-port scsi-qla0-adapter-port=21000018822c8a2c; scsi-qla1-adapter-port=21000018822c8a2d; 3. SUSE Linux 10 Check contents of the /sys/class/fc_host/host*/port_name file and obtain the WWN of corresponding Fibre Channel HBA cards. # cat /sys/class/fc_host/host*/port_name 0x210000e08b907955 0x210000e08b902856 4. RedHat Linux AS4 # grep scsi /proc/scsi/qla2xxx/3 Number of reqs in pending_q= 0, retry_q= 0, done_q= 0, scsi_retry_q= 0 scsi-qla0-adapter-node=20000018822d7834; scsi-qla0-adapter-port=21000018822d7834; scsi-qla0-target-0=202900a0b8423858; scsi-qla0-port-0=200800a0b8423858:202900a0b8423858:0000e8:1; 5. RedHat Linux AS5 # cat /sys/class/fc_host/hostx/port_name 6. Solaris 10 The fcinfo command is provided. You can use fcinfo hba-port to check the WWN of Fibre Channel HBA ports: # fcinfo hba-port Check the path and connection status of ports on the Fibre Channel card. # luxadm -e port 7. HP-UX Run # ioscan -funC fc // to find Fibre Channel HBA cards and use fcmsutil to check the information of Fibre Channel HBA cards. # fcmsutil /dev/fcd0(1) 8. AIX Use # lsdev -Cc adapter to find Fibre Channel HBA cards. # lscfg -vpl fcs0 |grep network address 9. Note The first digit of the WWN of Emulex's HBA cards is 1. The first digit of the WWN of Qlogic's HBA cards is 2. The first digit of the WWN of HP Tachyon HBA cards is 5. 10. Connection Options of the Qlogic parameter: 0 - Loop only 1 - Point-to-point only 2 - Loop preferred, otherwise point-to-point. You are advised to choose loop only when the direct attached storage is used and choose point-to-point only when the storage is connected to the Fibre Channel switch. 11. Data rate This configuration item defines the rate on the Fibre Channel port: 0 �?1 Gbit/s 1 �?2 Gbit/s 2 - Auto

16 Gbit/s Fibre Channel interface module
16 Gbit/s Fibre Channel interface modules are described as follows: A 16 Gbit/s Fibre Channel interface module has two 16 Gbit/s Fibre Channel ports. These ports are the service ports used to connect a storage system to application servers and to receive read/write requests from application servers. If the port speed is auto-negotiable, the port will auto-negotiate 4 Gbit/s, 8 Gbit/s, or 16 Gbit/s. If the port speed is manually set but inconsistent with the data transfer speed of the connected application server, the connection will be interrupted.

Indicators on an 8 Gbit/s Fibre Channel interface module
Indicators on an 8 Gbit/s Fibre Channel interface module are described as follows: Power indicator/Hot swap button Steady green: The interface module is working correctly. Blinking green: The interface module receives a hot swap request. Steady red: The interface module is faulty. Off: The interface module is powered off or is hot-swappable. 8 Gbit/s Fibre Channel port Link/Speed indicator Steady blue: Data is transferred between the storage system and application server at a rate of 8 Gbit/s. Blinking blue: Data is being transferred. Steady green: Data is transferred between the storage system and application server at a rate of 2 Gbit/s or 4 Gbit/s. Blinking green: Data is being transferred. Steady red: The port is faulty. Off: The link to the port is down.
