powerpath on Linux

[John Guster]

Why it is "UNKNOWN" instead of lpfc in Path field and is "unknown" in the I/O Paths field in the powermt display?

I strongly suggest you upgrade to PowerPath 5 (latest version is 5.3.1 SP1), 4.5.1 is no longer supported.
Also make sure the HBA drivers are listed in EMC Storage Interoperabilty Matrix, if you don't have access to EMC Powerlink to check, please let me know:
1) HBA Model
2) OS Version
3) HBA Driver Version
4) Storage Array Model and Firmware (Code) Version.
