How get WWN numbers for disks

Etienne Holm — Fri, 11 Jul 2008 08:36:48 GMT

I have several HP_UX servers with a large number of LUNS assignd from an EVA storage device.

These systems was build by a 3rd party and we have to reorg the LVM configs.

How can I get the WWN number for each disk and how do I then work it back to an device/HW path

For the EVA you can download and install "evainfo".

The only options I seem to be able to do is:
Usage : scsimgr -o old_target_name -n new_target_name -H interface_hw_path

Is there a manager tool that I sould install to get the information or is there standard HP commands that will give this to me.

Hi Holm,

You are probably looking for "evainfo".

Download and install it from the below link.

hi,

if you have autopath or spmgr, you can also get the info that you want.
