ASM instance fails to startup but can occur for RDBMS instances


Symptoms

CRS starts up successfully on the newly added node but the ASM instance fails to start and causes all ASM instances in the cluster to crash with:

Maximum Tranmission Unit (mtu) of the ether adapter is different
on the node running instance 4, and this node.
Ether adapters connecting the cluster nodes must be configured
with identical mtu on all the nodes, for Oracle.
Please ensure the mtu attribute of the ether adapter on all
nodes are identical, before running Oracle.
