- NetApp HCI
- Cluster with single compute node
- Firmware (FW) upgrade using HCC
No, you need at least 2 compute nodes in the cluster
- Workaround: install FW bundle manually
- Prerequisites for HCI installation: "The minimum cluster for NetApp HCI is two storage and two compute nodes."
- HCC upgrade will fail with:
"No ESXi hosts are available. Make one or more ESXi host(s) in cluster available (not in maintenance mode) to migrate virtual machines and run the health check again."
