8.7Troubleshooting Flowcharts

This section provides troubleshooting flowcharts to illustrate common troubleshooting methods.

The flowcharts included in this section are:

■“Power Supply and Fan Module” on page 8-11

■“Drive LEDs” on page 8-13

■“Front-Panel LEDs” on page 8-16

■“I/O Controller Module” on page 8-21

For the JBOD and expansion unit flowchart, see “Troubleshooting SANnet II 200 FC JBOD Arrays” on page B-12.

For overview information about LEDs, see Chapter 6.

For information about replacing modules, refer to the SANnet II Family FRU Installation Guide.

Caution – Whenever you are troubleshooting and replacing components, there is an increased possibility of data loss. To prevent any possible data loss, it is a good idea to back up user data to another storage device prior to troubleshooting your array.

Set up an IP address for the controller 5.1.1 Point-to-Point Configuration Guidelines Caution - If you keep the default loop mode and connect to a fabric switch, the array automatically shifts to public loop mode. As a result, communication between the array and the switched fabric runs in half duplex send or receive instead of providing the full duplex send and receive performance of point-to-point mode 5.1.2 A Sample SAN Point-to-Point Configuration Remember these important rules Map LG1 to SIDs 45 and Note - These illustrations show the default controller locations however, the primary controller and secondary controller locations can occur in either slot and depend on controller resets and controller replacement operations 2.
