環境

• Red Hat Enterprise Linux 5
• Red Hat Enterprise Linux 6
• Red Hat Enterprise Linux 7
• FC/FCoE Host Bus Adapter (QLogic, Emulex, Brocade, Cisco, etc.)

問題

• How to check HBA host and its corresponding WWPN?
• How do I lookup WWN of installed HBAs?
• How do I locate the world wide number of an hba WWPN (world wide port name)?
• How do I locate the world wide name of an hba?
• How to find out which Port Name is being used by an HBA Fibre Channel port?
• I need to associated my HBA ports WWPN within the Fibre Channel switch. How can I found out the correct name?

決議

• For more information about setting up SAN storage refer to the appropriate storage guide:

  • RHEL5: Online Storage Reconfiguration Guide
  • RHEL6: Storage Administration Guide
  • RHEL7: Storage Administration Guide.

• The wwpn (world wide port name) and companion wwnn (world wide node name) of an hba within the current configuration are available within the sysfs tree, can be found using a find

   command and viewed either via systool command from sysfsutils package (#yum install sysfsutils), or via simple grep command:

Raw

$ find /sys/class/fc_host/*/ -name 'port_name'             << retrieve path to wwpn entry
$ find /sys/class/fc_host/*/ -name 'node_name'             << retrieve path to wwnn entry


$ grep -v "zZzZ" -H /sys/class/fc_host/host*/*_name
/sys/class/fc_host/host6/fabric_name:0x100000051e900105    << switch port name, wwpn
/sys/class/fc_host/host6/node_name:0x200000e08b87de9a      <<    HBA node name, wwnn
/sys/class/fc_host/host6/port_name:0x210000e08b87de9a      <<    HBA port name, wwpn
/sys/class/fc_host/host6/symbolic_name:QLE2462 FW:v7.03.00 DVR:v8.07.00.18.07.2-k

In the case where it is insufficient to know just the WWNN/WWPN that exists for a scsi host and it is desired 
to know the actual pci address assigned to a particular scsi host -- then the following can be used:
$ find ./sys/devices -type d -name 'host*' | egrep -v "host_busy|fc_host|scsi_host" | sort
./sys/devices/pci0000:00/0000:00:01.0/0000:04:00.0/host4
./sys/devices/pci0000:00/0000:00:04.0/0000:08:00.0/host10

./sys/devices/pci0000:00/0000:00:07.0/0000:0e:00.1/host9
./sys/devices/pci0000:00/0000:00:0a.0/0000:14:00.0/host6   <<   card pci address for host6/scsi6
./sys/devices/pci0000:00/0000:00:0a.0/0000:14:00.1/host7

• Additional information is available within "How do I find the FC ID (WWN) of a disk/LUN", which discusses end-to-end transport identification (disk, scsi address, host [hba/pci address], switch port, storage port, lun). This references an unsupported/as-is utility called mapdevs that can be run on RHEL 5, 6, and 7 to display, among other things, an hba-to-storage wwn map.
