Error description

  • IBM PureApplication users with DNS servers outside
    PureApplication may experience DNS connection errors while
    trying to connect to external hosts from PureApplication
    Virtual Machines through DNS.
    
    Users having DNS servers (primary and secondary) outside
    PureApplication Systems may have multiple VLANs effected.
    
    The troubleshooting steps in the 'How IBM PureApplication
    System uses DNS to deploy workloads onto the data center's
    network' can be utilized to see if there is a persistent
    configuration or network problem.
