Hi,

here's my investigation

Code:
NODE01:~ # multipath -ll ocr-vote-mirror-1
ocr-vote-mirror-1 (3600507630080828c4000000000000016) dm-15 IBM     ,2145
size=500M features='1 queue_if_no_path' hwhandler='0' wp=rw
`-+- policy='round-robin 0' prio=30 status=active
  |- 7:0:0:20 sdv  65:80  active ready running
  `- 8:0:0:20 sdas 66:192 active ready running
  
NODE01:~ # /lib/udev/scsi_id --whitelisted --device=/dev/sdv
3600507630080828c4000000000000016
NODE01:~ # /lib/udev/scsi_id --whitelisted --device=/dev/sdas
3600507630080828c4000000000000016

NODE01:~ # ls -l /dev/mapper/ocr-vote-mirror-1*
lrwxrwxrwx 1 root root 8 Apr 18 15:14 /dev/mapper/ocr-vote-mirror-1 -> ../dm-15
lrwxrwxrwx 1 root root 8 Apr 18 09:08 /dev/mapper/ocr-vote-mirror-1_part1 -> ../dm-46
NODE01:~ # ls -l /dev/sdv*
brw-rw---- 1 root disk 65, 80 Apr 17 14:06 /dev/sdv
NODE01:~ # ls -l /dev/sdas*
brw-rw---- 1 root disk 66, 192 Apr 17 14:06 /dev/sdas
At node01, both /dev/sdv and /dev/sdas are not reflected as partitioned.
Code:
  
NODE02:~ # multipath -ll ocr-vote-mirror-1
ocr-vote-mirror-1 (3600507630080828c4000000000000016) dm-15 IBM     ,2145
size=500M features='1 queue_if_no_path' hwhandler='0' wp=rw
`-+- policy='round-robin 0' prio=30 status=active
  |- 7:0:0:20 sdv  65:80  active ready running
  `- 8:0:0:20 sdas 66:192 active ready running
  
NODE02:~ # /lib/udev/scsi_id --whitelisted --device=/dev/sdv
3600507630080828c4000000000000016
NODE02:~ # /lib/udev/scsi_id --whitelisted --device=/dev/sdas
3600507630080828c4000000000000016

NODE02:~ # ls -l /dev/mapper/ocr-vote-mirror-1*
lrwxrwxrwx 1 root root 8 Apr 18 15:21 /dev/mapper/ocr-vote-mirror-1 -> ../dm-15
lrwxrwxrwx 1 root root 8 Apr 17 14:51 /dev/mapper/ocr-vote-mirror-1_part1 -> ../dm-32
NODE02:~ # ls -l /dev/sdv*
brw-rw---- 1 root disk 65, 80 Apr 17 14:08 /dev/sdv
NODE02:~ # ls -l /dev/sdas*
brw-rw---- 1 root disk 66, 192 Apr 17 14:08 /dev/sdas
same things happen at node02, both /dev/sdv and /dev/sdas are not reflected as partitioned.

I partitioned by

Code:
fdisk /dev/mapper/wwid
from https://www.suse.com/documentation/s...piosysconfpart

Partitioning devices that have multiple paths is not recommended, but it is supported.
Am I doing the correct thing or wrong things that's why things don't turn up as expected?

many thanks in advance.
