I am trying to construct an IBM ICP cluster (aka docker).

The issue I am running into is that to build out a scaleable cluster, I need uniformity that the yaml file can call against when it creates the container LVM storage. But with the number of systems I am building , though all see the correct disk "uuid" and multipath is showing it correctly on all nodes... it shows to the kernel as different names

Ex: some see it as /dev/mapper/mpatha while others is /dev/mapper/mpathd etc...

I want to create uniformitiy so created per the redhat document a udev rule:
vi /etc/udev/rules.d/20-names.rules

#

KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s %p", RESULT=="600507680C808191E0000000000000F6",SYMLINK+="icp_intel_v90001_00"

#

but it does not work.

I posted this to the centos forum as I opened a ticket with IBM.. five days ago and still no help... so .. though I know all my redhat is via IBM "first level support and can't call and open ticket... I cant wait any longer for this.. this is holding up demos for customers.
