Prerequisite

CAUTION

: The VASA provider must be unregistered before you to initiate any of these tasks:

• Any action related to uninstallation, migration, upgrade, reinstalling of Storage Manager on same host with same IP address

• Uninstalling Storage Manager with the intention of reinstalling on another host

• Changing the Storage Manager FQDN

• Changing the Storage Manager IP address

Unregistering VASA will aects control plane operations on virtual volume VMs and datastores which are in use. It does not aect data

transfer between an ESXi host and the respective SAN storage.

Unregistering the VASA provider results in powered-o VVol VMs being shown as inaccessible and datastores as inactive. To avoid

prolonged control plane down time, minimize the period where the VASA provider remains unregistered. After re-reregistration, there

could be a delay for powered-o VMs and datastores to recover from being inaccessible and inactive respectively.
