Powering on the storage array
After replacing a controller canister, you must bring the controller online and confirm that the storage
array is working correctly. Then, you can collect support data and resume operations.
About this task
If the controller upgrade involves a protocol change (for example, Fibre Channel to iSCSI), any hosts
groups, hosts, and volume-to-LUN mappings defined in the host mappings tab remain intact.
However, you must take steps to associate the new host ports with the hosts. If the controller upgrade
does not involve a protocol change, all host port mappings will remain intact and no additional steps
are required.
Steps
1. Turn on the Power switch on the rear of each drive tray that is connected to the controller-drive
tray.
2. Wait two minutes for the drives to spin up.
3. Turn on the Power switch on the rear of the controller-drive tray.
4. Wait three minutes for the power-up process to complete.
5. If you saved a security key in
Preparing to Replace the Controllers
on page 11, perform the
following steps on each controller to import that key.
a. If there is a mix of secured and unsecured drives in the storage array, create a new security
key.
Unsecured drives are unassigned drives, GHS drives, or drives which are part of a volume
group or a disk pool that is not secured by Drive Security. Secured drives are assigned drives
that are a part of a secured volume group or Disk Pool using Drive Security.
b. Import the security key that you saved in
Preparing to Replace the Controllers
on page 11.
(From the Storage Array menu, select Security > Drive Security > Import Key.)
c. If there were only secured drives (no unsecured drives) in the storage array, the controller(s)
will automatically reboot to complete the import operation. Wait for all controllers to boot up.
When a controller finishes booting, its icon will appear in the Enterprise Management
Window (EMW).
6. If the Drive Security feature is enabled, and the storage array has a mix of secured and unsecured
drives, follow these steps:
a. Run the
set allDrives nativeState
SMcli command.
b. Reset all controllers using SANtricity Storage Manager.
c. Wait for all controllers to boot up. When a controller has finished booting, it appears in the
EMW.
7. Look at the LEDs on controller A to make sure that it is booting correctly.
The Host Link Service Action Required LEDs turns green during the reboot. 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. You can
then discover the new controller canister by using the storage management software.
