ioscan shows 2 different device names on same HW path

Hello all

 

Does this look normal to you? Could it be a disk can contain 2 different device names on same HW path?(Check the red)

we have no alternate pathing.

 

# ioscan -fnH 6/0/1/1/0/4/0.0.0
Class     I  H/W Path       Driver   S/W State   H/W Type     Description
==========================================================================
disk      0  6/0/1/1/0/4/0.0.0  sdisk    CLAIMED     DEVICE       HP 73.4GST373454LC
                           /dev/dsk/c0t0d0     /dev/dsk/c0t0d0s2   /dev/dsk/c2t0d0s1   /dev/rdsk/c0t0d0    /dev/rdsk/c0t0d0s2  /dev/rdsk/c2t0d0s1
                           /dev/dsk/c0t0d0s1   /dev/dsk/c0t0d0s3   /dev/dsk/c2t0d0s2   /dev/rdsk/c0t0d0s1  /dev/rdsk/c0t0d0s3  /dev/rdsk/c2t0d0s2

Re: ioscan shows 2 different device names on same HW path

There is something wrong.

I would do

# rmsf -H 6/0/1/1/0/4/0.0.0

# insf -e

(remove and re-create the special files)

Hope this helps!
Regards
Torsten.

Re: ioscan shows 2 different device names on same HW path

ioscan is matching up hardware paths with the device files. Use the command:

 

lssf /dev/*dsk/* | grep 6/0/1/1/0/4/0.0.0

 

This will show you all the device files that have the same path. There's probably no way to guess how that device file came to exist although adding and deleting disks without using rmsf -H may be a contributor.
