Is the host link status LED on?
■ Yes – You have isolated the fault to the HBA. Replace the HBA.
■ No – It is likely that the controller module needs to be replaced.
6. Move the cable back to its original port.
Is the host link status LED on?
■ No – The controller module’s port has failed. Replace the controller module.
■ Yes – Monitor the connection for a period of time. It may be an intermittent
problem, which can occur with damaged cables and HBAs.
Isolating a Controller Module Expansion Port
Connection Fault
During normal operation, when a controller module’s expansion port is connected to
a drive enclosure, the expansion port status LED is green. If the connected port’s
expansion port LED is off, the link is down. Use the following procedure to isolate
the fault.
This procedure requires scheduled downtime.
Note – Do not perform more than one step at a time. Changing more than one
variable at a time can complicate the troubleshooting process.
1. Halt all I/O to the storage system.
2. Check the host activity LED.
If there is activity, halt all applications that access the storage system.
3. Reseat the expansion cable.
Is the expansion port status LED on?
■ Yes – Monitor the status to ensure there is no intermittent error present. If the
fault occurs again, clean the connections to ensure that a dirty connector is not
interfering with the data path.
■ No – Proceed to Step 4.
