Possible symptoms:

  • There are a combination of FC-VI adapter disconnection errors or transport errors in the ems-log when accessing disks at the remote site:

  • The Brocade Switches report that one or more ISL interfaces reset:

  • The node reports failed disks at the other site:

  • LUNs can experience connections/disconnections, hence LUNs might be inaccessible.
