3. Look at the LEDs on both controller canisters to make sure that the controllers
are booting correctly.
The seven-segment display shows the sequence OS+ Sd+ blank- to indicate
that the controller is performing Start-of-day (SOD) processing. After the
controller successfully completes rebooting, the seven-segment display shows the
tray ID matching the seven-segment display on the second controller. After this
time, you can discover the controllers by using the storage management software.
From the Hardware pane in the Array Management
Window, right-click the picture of the controller, and
select Advanced >> Place >> Online.
Enter the following command on the command line:
smCLI
<DNS-network-name-or-IP-address> -c
"set controller [a]
availability=online";
In this command,
<DNS-network-name-or-IP-address> is
the applicable address.
