OmniStack upgrades are initiated against the Federation and are completed in an automated, rolling fashion. OmniStack Accelerator Card upgrades are included in the OmniStack upgrade process. Reboots of a host are only required if there is an associated OmniStack Accelerator Card firmware update. The updating of the firmware only happens occasionally.
HPE SimpliVity 380 provides a Fast Upgrade Manager that manages the entire upgrade process, from detection to execution.
HPE SimpliVity 380 OmniStack 3.7.7 provides Upgrade Manager support for simulteaneously upgrading hosts in a cluster when the hosts do not have powered-on guest VMs, accelerating the upgrade process.
HPE SimpliVity 380 OmniStack 3.7.9 provided Upgrade Manager support for upgrading HPE OmniStack software at the cluster level. This feature only works when upgrading from HPE OmniStack 3.7.8 to HPE OmniStack 3.7.9.
