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 Dell
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 would 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
DellStorage 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 networking
properties on the host. Then follow the Dell Storage Manager procedure for
deleting existing certificates and restart the Storage Manager. After the restart,
re-register the VASA Provider.
FQDN changes on Windows or Virtual Appliance If certificates are already using FQDN and you want to change the FQDN,
unregister VASA Provider first. Then make changes to the name lookup service or
Storage Manager host (or both) for the new FQDN. Then follow the old procedure
for deleting certificates and restart Storage Manager. Re-register VASA Provider
after Storage Manager is running.
NOTE: Failure to unregister the VASA Provider before making changes
in name lookup service results in initialization errors on vCenter for
certain services and causes VASA registration to fail.
Switching from FQDN to IP Address on DellStorage
Manager
If you want to stop using FQDN and go back to using IP addresses, unregister the
VASA Provider first. Then make changes to the name lookup service or Storage
Manager host (or both) to remove FQDN configuration. Restart Storage Manager
for the changes to take effect and register VASA Provider again.
