Place controller online (duplex)
Place the controller online to confirm the storage array is working correctly. Then, you can collect
support data and resume operations.
About this task

As the controller boots, check the controller LEDs and the seven-segment display.

number and a different type of host ports.

• The seven-segment display shows the repeating sequence OS, OL, blank to indicate that the
controller is offline.
• The amber Attention LED remains lit.
• The Host Link LEDs might be on, blinking, or off, depending on the host interface.
