matching LUNs to hardware paths

[Susan Eck]

I have an FC60 array shared by three N4000 servers, which has the disks hardware-mirrored. When I do an "amdsp -a" I can see the LUN numbers, enclosure, and slots. I use ioscan to associate the device files with the hardware paths. But how do I know which LUNs go with which hardware paths/device files of the disks?

A single LUN may consist of many disks and since FC60 is an Array It will be stripped on all the disks. So you can't associate the drives alongwith the LUNs.

I go to SAM -> Disk and File Systems -> Disk Devices. Each Disk Array LUN is listed. Select each one and under Actions, do View More Information. Hit the Show Device Files to see them.

Hi Susan:

Other options:

1) Run 'stm' and get information about the controller and LUN. This will give you the disk's information.

2) Run the FC60 array utility which normally comes with the array.

3) Run SAM -> disk and file systems -> Disk devices -> LUN

HTH,
