8. Move the power supplies from the existing controller to the upgrade controller.
Skip this step if you upgraded the power supplies.
a) Push the power supply release lever to the left, grasp the handle, and pull the power supply out of the bay.
1 Power supply release lever
b) Slide the power supply into a bay of the controller until it clicks into place.
c) Repeat this action with the other power supply. A power supply can be installed in either bay of the controller.
9. Install the controller.
a) Make sure the controller release lever is fully extended.
b) Slide the controller into the chassis bay. Do not force the controller. If it does not slide in easily, remove it and retry.
c) After the controller is in place, return the controller release lever to its original closed position until the catch clicks.
d) Reconnect all the cables to the controller (as labeled from step 2).
If you are reusing 800W PSUs with HPE Alletra 6030 or 6050, refer to Cabling Power With Underpowered PSUs on
page 121 for instructions on correctly cabling PSUs and controllers.
10. Verify that the controller is powered on.
Once installed, the controller powers on automatically. The controller LEDs on both the left and right side of the array
remain on. If the controller does not power on automatically, contact HPE Support.
11. Verify that the array recognizes the new controller and that the new controller is in Standby mode.
Do one of the following:
In the GUI, click Hardware, then look for the controller labeled STANDBY.
In the CLI, enter the command: ctrlr --list --array array_name, then look for the controller labeled standby.
Note: The new controller might take up to 90 minutes to appear in the user interface because some firmware
components on the new controller must be updated by the array OS.
Do not remove the controller during this period because interrupted firmware updates might render the hardware
non-functional.
If the controller takes longer than 90 minutes to report an Active/Standby state, contact HPE Support for assistance.
12. While still logged in to the array, perform a failover to the new controller.
Type failover --array array_name
13. After failover, verify that the new controller is in the expected mode.
ctrlr --list --array array_name
During the failover, the Standby controller first goes into solo mode and then into Active mode. The previously active
controller goes into unknown mode, then into Stale mode, and finally into Standby mode.
For HPE Alletra 6010 only: During the failover, the Standby controller goes into Solo mode. The previously active controller
goes into unknown mode and then into Stale mode.
14. Repeat steps 2 through 11 for the other controller, now in Standby mode.
