Environment

Open Enterprise Server 2018 (OES 2018) Linux

Situation

Existing cluster of OES 2015 SP1 nodes cluster on physical hardware or VMware virtualized.

The shared disks are in a SAN that is connected per Fibre Channel to host bus adapters of the cluster nodes.

SAN connected the to a host bus adapter of an ESXi 6.5 host and created a Raw Disk Mapping for each shared disk of the SAN, also for the SBD partition.

New OES 2018 server as VMWare guest on the ESXi 6.5 host is created and added it to the cluster.

When booting the OES 2018 cluster node, which is a VMWare guest at the ESXi 6.5 host, it crashes as soon as sbdlib.ko is loaded.

dmesg reads the following details about the crash:
