● Changing the Storage Manager IP address
Unregistering VASA will affects control plane operations on virtual volume VMs and datastores which are in use.
It does not affect data transfer between an ESXi host and the respective SAN storage.
Unregistering the VASA provider results in powered-off 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-off VMs and datastores to recover
from being inaccessible and inactive respectively.
Steps

Using Storage Manager Certificates With VASA Provider
When you run the Register VASA Provider wizard, the URL of the VASA provider is automatically generated. This URL
identifies the host on which the Data Collector is installed. The host is identified as either an IP address or fully qualified domain
name (FQDN). Depending on how you installed or upgraded Storage Manager or if you changed the host for the Data Collector,
you might need to take additional steps to update the certificates.
New Installation of Dell Storage Manager
If Storage Manager is registered with a name lookup service such as DNS server or Active Directory server, Storage Manager
certificates are generated based on its FQDN. Any IP address changes do not affect certificates. If you change the FQDN,
Storage Manager must be manually restarted if it is a Windows-based installation. It is automatically rebooted for the Virtual
Appliance installation. If you were using the VASA provider before the IP changes, you must unregister and then register VASA
Provider manually.
Upgrade of Dell Storage Manager
In Dell Storage Manager, certificates are based on IP addresses. After an upgrade to Dell Storage Manager, the existing
certificates remain unchanged. If you need to modify the IP address of the host, the certificates need to be updated as
described in the following table:
IP Change
Action Required
IP changes on Windows-based Storage
Manager
If Storage Manager is not registered with a name lookup service such
as DNS server or Active Directory, then Storage Manager and VASA
certificates are based on the IP address of the Windows host. Before the
IP address of the Windows host is changed, you must first unregister the
VASA Provider. Then modify the IP address of the Windows host. Then
manually restart Storage Manager to regenerate certificates based on the
new IP address. After the restart, you must re-register the VASA Provider.
IP changes on the Virtual Appliance On a Dell Storage Manager Virtual Appliance, network changes such as IP
address happen through the Storage Manager and hence Storage Manager
is aware of the changes. You must first unregister and the VASA Provider,
then make the changes to the IP address. After the changes are done,
Storage Manager restarts itself to regenerate certificates based on the new
IP address. You then must re-register the VASA Provider.
Switch from an IP Address to an FQDN on Dell
Storage Manager
To switch the certificates to use the FQDN instead of the IP address of
the host, you must first unregister and the VASA Provider. Then register
the Storage Manager host with a name lookup service. Then configure the
