Using Storage Manager Certicates With VASA Provider
When you run the Register VASA Provider wizard, the URL of the VASA provider is automatically generated. This URL identies the
host on which the Data Collector is installed. The host is identied as either an IP address or Fully-Qualied 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 certicates.
New Installation of Dell Storage Manager 2016 R2
If Storage Manager is registered with a name lookup service such as DNS server or Active Directory server, Storage Manager
certicates are generated based on its FQDN. Any IP address changes do not aect certicates. 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 2016 R1 to Dell Storage Manager 2016 R2
In Dell Storage Manager 2016 R1, certicates are based on IP addresses. After an upgrade to Dell Storage Manager 2016 R2, the
existing certicates remain unchanged. If you need to modify the IP address of the host, the certicates 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 certicates are
based on the IP address of the Windows host. Before the IP address of the
Windows host is changed, you must rst unregister the VASA Provider. Then
modify the IP address of the Windows host. Then manually restart Storage
Manager to regenerate certicates 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 Web UI and hence Storage
Manager is aware of the changes. You must rst unregister and the VASA
Provider, then make the changes to the IP address. After the changes are
done, Storage Manager restarts itself to regenerate certicates 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 2016 R2
To switch the certicates to use the FQDN instead of the IP address of the
host, you must rst unregister and the VASA Provider. Then register the
Storage Manager host with a name lookup service. Then congure the
networking properties on the host. Then follow the Dell Storage Manager 2016
R1 procedure for deleting existing certicates and restart the Storage Manager.
After the restart, re-register the VASA Provider.
FQDN changes on Windows or Virtual Appliance If certicates are already using FQDN and you want to change the FQDN,
unregister VASA Provider rst. 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 certicates 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 2016 R2
If you want to stop using FQDN and go back to using IP addresses, unregister
the VASA Provider rst. Then make changes to the name lookup service or
