  • Switchless cluster to BES-53248 cluster switch conversion

Issue

  • Following the below procedure to migrate from 2 node switchless cluster to switched cluster with BES-53248 cluster switches:

     Migrate to a switched NetApp cluster environment using Broadcom-supported BES-53248 cluster switches

  • Each node has e0a cluster port connected to new cluster switch cs1
  • The e0b cluster ports are still connected to each other
  • There is a link error (port flapping due to faulty cable) on one of the links connected to the new switch
  • The following is seen on the affected node:
