You need to know, what is version of your HBA firmware to upgrade it or install compatible driver version. There is many ways to find firmware version but I want to share easier way. Just logon to your Linux machine with Sudo user and run the below command: cat /sys/class/fc_host/host*/symbolic_name
Device Naming Device name management is handled by udev system. When Linux kernel discovers a new device (e.g., a network interface card) added to the system, it notifies udev daemon of the device event. The udev daemon will then match various device attributes against a set of rules to identify the device, name it, and store its information in udev database. In case of network devices, udev relies on MAC addresses to assign persistent names to the devices. The MAC address based naming rules are stored in “/etc/udev/rules.d/70-persistent-net.rules”.
What’s UUID? A universally unique identifier (UUID) is a 128-bit number used to identify information in computer systems. Microsoft uses the term globally unique identifier (GUID), either as a synonym for UUID or to refer to a particular UUID variant. When generated according to the standard methods, UUIDs are for practical purposes unique, without requiring a central registration authority or coordination between the parties generating them. The probability that a UUID will be duplicated is not zero, but is so close to zero as to be negligible. Thus, anyone can create a UUID and use it to identify something with near certainty that the identifier does not duplicate one that has already been created to identify something else, and will not be duplicated in the future. Information labeled with UUIDs by independent parties can therefore be later combined into a single database, or transmitted on the same channel, without needing to resolve conflicts between identifiers.
