lun number map to a device file name

Hi Fellas,
We have an HP EVA 8100 with HP-UX 11.23 and 11.31 hosts connected to it.
I’m wondering if there is a unique mapping between a LUN in the EVA with a device file name in a host.
For example, on a host I have
/dev/rdsk/c25t0d1 LUN 1
/dev/rdsk/c25t0d2 LUN 2
/dev/rdsk/c25t0d3 LUN 3
/dev/rdsk/c29t15d2 LUN 250
If this is the case, I want to use the LUN number to get the device file name in the host and remove it later after a snap clone is done.
Your answer will be highly appreciated.

Hi,

the device file is almost meaningless, you need the hardware path!

See this thread from this week:

Hope this helps!
