A state a host is placed in, only on request, so that it can be serviced. Entry completes only once every running VM has been moved off or shut down, and vSAN hosts additionally require a choice about how their data is handled.

Terms in this definition
- State
A parameter in OAuth that carries custom data through the authorisation flow and back, as with the "Support state parameter" option in APIM.
- vSAN
VMware's software-defined storage, which combines local devices across a cluster's ESX hosts into one shared datastore. Available as OSA or ESA, VCF can use it as principal storage.
Related terms
- Live Patch
A vSphere Lifecycle Manager remediation method that installs eligible ESX patches without putting hosts into maintenance mode, restarting them or moving VMs off. It applies to image-managed clusters that have DRS enabled.
- Proactive HA
When a hardware vendor's monitoring reports degraded health on a host, for instance a dead power supply, this vSphere capability clears VMs off it and moves the host into quarantine or maintenance mode. DRS has to be enabled for it to work.
- remediation
Applying updates through vSphere Lifecycle Manager, entering maintenance mode where needed, so that every cluster and host ends up compliant with its image or baselines. Readiness can first be confirmed by a pre-check that changes nothing.
- staging
Pre-loading image components onto hosts with vSphere Lifecycle Manager, without applying them yet, so that hosts spend less time in maintenance mode when remediation runs.
