Upgrade of Dell Unisphere Central Dell Unisphere Central
In Dell Unisphere Central, certicates are based on IP addresses. After an upgrade to Dell Unisphere Central, 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 Unisphere Central If Unisphere Central is not registered with a name lookup service such as DNS
server or Active Directory, then Unisphere Central 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 Unisphere Central 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 Unisphere Central Virtual Appliance, network changes such as IP address
happen through the Unisphere Central and hence Unisphere Central 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, Unisphere Central 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
DellUnisphere Central
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 Unisphere
Central host with a name lookup service. Then congure the networking properties
on the host. Then follow the Dell Unisphere Central procedure for deleting existing
certicates and restart the Unisphere Central. 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
Unisphere Central 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 Unisphere Central 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
DellUnisphere Central
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 Unisphere
Central host (or both) to remove FQDN conguration. Restart Unisphere Central
for the changes to take eect and register VASA Provider again.
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.
Managing Storage Containers
You can create and use storage containers to organize VMware virtual volumes (VVols) in your environment.
A storage container is a pool of storage that is used in a VMware environment that supports VVols. Storage containers can be created
using the following methods:
• From the Storage view in the Navigation pane of Unisphere Central, select Volumes. Use the Create Storage Container function to
create the storage container and specify its settings.
