Upgrading firmware is a two-step process: uploading the firmware to UCP Advisor, and then upgrading the firmware on the respective devices in a UCP system.
By default, the device powers off with an orderly shutdown, which initiates OS shutdown before the system powers off.
For a table of supported compute BMC firmware upgrade paths from the previous two versions (n-2), see Supported compute BMC firmware upgrade paths.
For management server firmware upgrades, the conditions listed below apply per UCP system type.
UCP converged infrastructure (CI)
If there are three or more management nodes (with external Hitachi SAN datastores), the VMware HA/DR clusters are configured, and UCP Advisor is running on them along with VMware ecosystem management VMs, then UCP Advisor fully supports these hosts (onboard, inventory, power operations, firmware upgrades, bare metal OS provisioning (ESXi) deployments) in the same way it supports workload domain hosts.
UCP hyperconverged (HC)
If there are four or more management nodes with a vSAN (with FTT greater than or equal to 1) datastore, and with UCP Advisor running on them along with the VMware ecosystem management VMs, then UCP Advisor fully supports these hosts (onboard, inventory, power operations, firmware upgrades, bare metal OS provisioning (ESXi) deployments) in the same it supports workload domain hosts.
If there are three or more nodes (with external Hitachi SAN datastores), the VMware HA/DR clusters are configured, and UCP Advisor is running on them along with VMware ecosystem management VMs, then UCP Advisor fully supports these hosts (onboard, inventory, power operations, firmware upgrades, bare metal OS provisioning (ESXi) deployments) in the same way it supports workload domain hosts.
UCP rack scale (RS)
If there are four or more nodes with vSAN (FTT greater than or equal to 1) (that is, in VCF terms, management domain), and UCP Advisor is running on them along with VMware ecosystem management VMs, then UCP Advisor supports these hosts fully (onboard, inventory, power operations, firmware upgrades, bare metal OS provisioning (ESXi) deployments) in the same way it supports workload domain hosts.
