Port Troubleshooting Resolution Guide

From the picture above, note that this controller head (which is only one example) contains a lot of different ports which can behave differently in different configurations.

These can be divided into three groups:

  • SAS ports (marked with red circles) which are used to access the disk shelves. 
  • Ethernet ports (marked with green circles) used for end users to access data.
  • FC Ports Some of the ports, (half green- half orange), can be configured as FC ports, but are still used for end users to access data.
  • Management ports (wrench port and locked wrench port) are used for monitoring and managing the system.

Depending on port configuration or hardware issue with a particular port, the system can behave differently and the end result might be different.
