问题
- 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?

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
findcommand and viewed either viasystoolcommand from sysfsutils package (#yum install sysfsutils), or via simplegrepcommand:

- 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
mapdevsthat can be run on RHEL 5, 6, and 7 to display, among other things, an hba-to-storage wwn map.
