Refer to the following table to determine what models you can upgrade your controller model to.
Original Model
HPE Alletra 5030
HPE Nimble Storage HF40
HPE Nimble Storage HF40C
HPE recommends using the Maintenance Window functionality within the HPE InfoSight portal to inform HPE Support of
upcoming maintenance windows.
Refer to https://infosight.hpe.com/dashboards/nimble/wellness/maintenance-windows for more information.
You can disable automated support case generation during planned maintenance from the Manage Maintenance Windows
page. After a maintenance window is set, no further communication with HPE Support is required.
Note:
If one controller fails, the other controller takes over. The array can function with one healthy controller while the
new one is installed.
Upgrade controllers are shipped with empty PCIe cages installed. Before installing the new controller, you must
move the PCIe cage from the existing controller and install it into the new controller.
Replace the array controller if any of its components have failed. If replacing a controller, see Replace a Controller
on page 82.
If upgrading NICs or FC HBAs, see Upgrade PCIe Cards on page 115.
CAUTION:
Before you attempt to install the controller:
For HPE Alletra 5000 upgrades, ensure the array is updated to OS version 6.1.0.0 or later.
For HPE Nimble Storage arrays, if you are upgrading to an HF60 model, you must update to OS version 6.0.0.500
or later before performing the controller upgrade.
Do not remove the existing controller until you are ready to install the upgrade.
Determine which controller to upgrade before installation.
Determine the model and OS version running on the array, and the state of the controllers. See Check Array Model,
OS Version, and Operating State Using the GUI on page 59.
Synchronous replication:
Synchronous replication, with or without HPE Peer Persistence, cannot be configured when the array models do
not match. Do not start the upgrade unless all arrays in the group are being upgraded to the same model.
Synchronous replication cannot be enabled until all arrays have been upgraded.
If volumes are configured with Peer Persistence, create a snapshot before starting the controller upgrade. Then,
disable automatic group switchover (ASO) and unconfigure the synchronous replication volume collections. After
upgrading the controllers, reenable ASO and reconfigure the synchronous replication volume collections.
