Question about LUNS

Is there a way to work out a LUN from within the hardware path?

I dont think there is, but could someone clarify

Cheers

From hardware path, at most you can check which disk it is. Then you can do pvdisplay on the disk to know which lvols reside on that disk.

Given a hardware path eg: -

0/3/0/0.8.0.21.0.1.2

The LUN number can be calculated from the last three digits with the formula: -

0*128 + 1*8 + 2

= 10

The LUN ID for this path is 10.
