I have 2 different system and one is working correct.

How can I get following

Class I H/W Path Driver S/W State H/W Type Description
============================================================================
disk 0 8/0/19/0.6.0 sdisk CLAIMED DEVICE ATA SATA SSD
/dev/dsk/c0t6d0 /dev/rdsk/c0t6d0
disk 2 8/16/5.2.0 sdisk CLAIMED DEVICE FUJITSU M2512A
/dev/dsk/c1t2d0 /dev/rdsk/c1t2d0
/dev/dsk/mo3.5 /dev/rdsk/mo3.5

also on the 2nd system. The 2nd system looks like

I need to set it up, that the MO is same. There is an grafic system set up to work with this mount points.

You could start with

lssf /dev/dsk/mo3.5

to get more information.

Hi,

Thanks for answer.

I checked with lssf and I see, that the LUN is not the same where I cant run the MO. On the other system all settings are same and I can use all the installed shortcuts to get access to the MO drive.

How can I change the LUN from 0 to 1?

The folder /dev/dsk/mo3.5 is linked from /dev/dsk/c4t2d0.

Hello,

Good Day.

I suspect that comamnd "ioscan" shows "/dev/rdsk/mo3.5" or "/dev/dsk/mo3.5" against "c1t2d0" due to
same "minor" number assigned. I mean Minor number for /dev/dsk/mo3.5 is same as /dev/dsk/c1t2d0.

I have tried to simulate the issue in my LAB server ( OS: 11.31).

Before:
======
#ioscan -m lun
Class I Lun H/W Path Driver S/W State H/W Type Health Description
=======================================================================
disk 50 64000/0xfa00/0x23 esdisk CLAIMED DEVICE online HP P2000 G3 FC
0/0/4/1/0/4/0.0x217000c0ff11a036.0x4000000000000000
0/0/6/1/0/4/0.0x217000c0ff11a036.0x4000000000000000
/dev/disk/disk50 /dev/rdisk/disk50

Duplicating Minor number:
=======================
# ll /dev/disk/disk50
brw-r----- 1 bin sys 1 0x000023 Apr 16 2017 /dev/disk/disk50

# ll /dev/rdisk/disk50
crw-r----- 1 bin sys 13 0x000023 May 10 2019 /dev/rdisk/disk50

// Creating "/dev/disk/mo3.5" device file with same minor number.

## mknod /dev/disk/mo3.5 b 1 0x000023
# mknod /dev/rdisk/mo3.5 c 13 0x000023 < == same minor number as disk50

# ll /dev/disk/mo3.5
brw-rw-rw- 1 root sys 1 0x000023 May 15 18:41 /dev/disk/mo3.5

# ll /dev/rdisk/mo3.5
crw-rw-rw- 1 root sys 13 0x000023 May 15 18:43 /dev/rdisk/mo3.5

# ioscan -m lun

Hope this helps.

Hi Manjunath,

thanks for your help.

#ioscan -m LUN does not work under Unix 10.2

First I used ln, but by creating new with mknod, I got it working.

I make the linked folder new and got it working.

Best Regards
