• System ports: If you are using NetApp Hybrid Cloud Control for upgrades, you have ensured that the
necessary ports are open. See Network ports for more information.
• Minimum BMC and BIOS versions: The node you intend to upgrade using NetApp Hybrid Cloud Control
meets the following minimum requirements:
Model Minimum BMC version Minimum BIOS version
H300E, H500E, H700E 6.84.00 NA2.1
H410C All versions supported (no
upgrade required)
All versions supported (no
upgrade required)
H610C 3.96.07 3B01
H615C 4.68.07 3B08.CO
H615C compute nodes must update BMC firmware to version 4.68 using the compute
firmware bundle 2.27 to enable NetApp Hybrid Cloud Control to perform future firmware
upgrades.
A Redfish license is required for H300E, H500E, and H700E compute nodes to enable
NetApp Hybrid Cloud Control to perform future firmware upgrades. Contact NetApp
Support to get the license installed manually until a new compute firmware bundle
automates this process in a follow-on release.
For a complete matrix of firmware and driver firmware for your hardware, see this KB
article (login required).
•
BIOS boot order: Manually change the boot order in the BIOS setup for each node to ensure USB
CD/DVD appears in the boot list. See this article for more information.
• BMC credentials: Update the credentials NetApp Hybrid Cloud Control uses to connect to the compute
node BMC. You can do this using either the NetApp Hybrid Cloud Control UI or API. Updating BMC
information prior to upgrade refreshes the inventory and ensures that management node services are
aware of all hardware parameters needed to complete the upgrade.
• Attached media: Disconnect any physical USB or ISO before starting a compute node upgrade.
• KVM ESXi console: Close all open Serial-Over-LAN (SOL) sessions and active KVM sessions in the BMC
UI before starting a compute node upgrade.
• Witness Node requirements: In two- and three-node storage clusters, one Witness Node must be running
in the NetApp HCI installation at all times.
• Compute node health check: You have verified that the node is ready to be upgraded. See Run compute
node health checks prior to upgrading compute firmware.
About this task
In production environments, upgrade the firmware on one compute node at a time.
For NetApp Hybrid Cloud Control UI or API upgrades, your ESXi host will be automatically placed in
maintenance mode during the upgrade process if you have the DRS feature and required licensing. The node
will be rebooted and after the upgrade process is complete, the ESXi host will be taken out of maintenance
mode. For USB and BMC UI options, you will need to place the ESXi host in maintenance mode manually, as
described in each procedure.
