Explanation:
There are two approaches for monitoring Oracle Exadata Storage Servers: using a command-line interface
(CLI) or using the graphical interface provided by the Oracle Enterprise Manager Cloud Control 12c console.
You can manually monitor the InfiniBand Switch Ports with the ibqueryerrors.pl command.
Run the ibqueryerrors.pl command to report on switch port error counters and port configuration information using the command:
# ibqueryerrors.pl -rR -s RcvSwRelayErrors,XmtDiscards,XmtWait,VL15DroppedReferences: http://www.oracle.com/technetwork/articles/servers-storage-admin/monitor-exadata-em12-
