Complete controller replacement (duplex)

You complete the controller replacement by placing the controller online and confirming that the storage
array is working correctly. Then, you can collect support data and resume operations.
Procedure
1. As the controller boots, check the controller LEDs and the seven-segment display.
When communication with the other controller is reestablished:
• The seven-segment display shows the repeating sequence OS, OL, blank to indicate that the
controller is offline.
• The amber Attention LED remains on.
• The Host Link LEDs might be on, blinking, or off, depending on the host interface.

2. Check the codes on the controller's seven-segment display as it comes back online. If the display shows
one of the following repeating sequences, immediately remove the controller.
• OE, L0, blank (mismatched controllers)
• OE, L6, blank (unsupported HIC)
Attention: Possible loss of data access – If the controller you just installed shows one these
codes, and the other controller is reset for any reason, the second controller also could lock down.
3. When the controller is back online, confirm that its status is Optimal and check the controller shelf's
Attention LEDs.
If the status is not Optimal or if any of the Attention LEDs are on, confirm that all cables are correctly
seated and the controller canister is installed correctly. If necessary, remove and reinstall the controller
canister.
Note: If you cannot resolve the problem, contact technical support.
