Upgrade Controllers (Af40) - Hewlett Packard Enterprise AF20 Hardware Manual

Upgrade Controllers (AF40)

• 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 45 minutes to appear in the user interface because some firmware
components on the new controller must be updated by the NimbleOS.
Do not remove the controller during this period because interrupted firmware updates might render the
hardware non-functional.
If the controller takes longer than 45 minutes to report an Active/Standby state, contact HPE Nimble
Storage Support for assistance.
16 While still logged in to the array, perform a failover to the new controller.
failover array_name
17 After failover, verify that the new controller is in the expected mode.
ctrlr --list --array array_name
For HF20, HF20H, and HF20C: During the failover, the Standby controller goes into Solo mode. The
previously active controller goes into unknown mode and then into Stale mode.
For AF20: During the failover, the Standby controller 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.
18 Repeat steps 2 through 15 to upgrade the other controller.
For HF20, HF20H, and HF20C: Shortly after both controllers are upgraded, the active controller
automatically fails over a second time to upgrade the NVRAM format.
19 Verify that the controllers are in Active and Standby modes.
ctrlr --list --array array_name
20 Verify that the model number of the array has changed.
shelf --array array_name --list
Look for Model in the list of information.
21 Prepare and return both replaced controllers and PCIe cages.
a) Lower the PCIe cage back into the controller, making sure that the PCIe cage aligns with the guide
pins, and that the riser card with the bridge board connector aligns with the bridge board. Press down
on the top of the PCIe cage ensuring that both riser cards and the bridge board connector are properly
seated.
b) Return the controller shroud into position.
c) Tighten the bottom thunbscrew on the PCIe cage.
d) Return the components using the RMA instructions that came with the upgrade kit.
