2.2.6. Step 6: Place controller online
For a duplex configuration, place the controller online, collect support data, and resume operations.
Perform this task only if your storage array has two controllers.
Steps
1.
As the controller boots, check the controller LEDs and the seven-segment display.
The figure shows an example controller canister. Your controller might have a
different number and a different type of host ports.
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 lit.
◦ The Host Link LEDs might be on, blinking, or off, depending on the host interface.
(1) Host Link LEDs (Controllers without two base-board ports on the rear do not have the
LEDs.)
(2) Attention LED (Amber)
(3) Seven-segment display
