I am bit curious to know how could we differentiate LUN and Local disk ,without a HUK / Sansurfer packages installed ?.We came across such a difficulty in an incompatible machine that doesnt have any package to install.
LUN id is the unique identifier between the host and the filer (storage) to differentiate between LUNs. There should be a way to find the LUN using serial number. I am currently not aware of it. Will let you know if I find anything.
