Adding and Organizing Storage Centers
Adding and organizing Storage Centers can only be done using Unisphere Central connected to a Data Collector.
Note the following restrictions about Unisphere Central user accounts:
● An individual Unisphere Central user can view and manage only the Storage Centers that have been mapped to his or her
account. In other words, the Storage Centers that are visible to one Unisphere Central user are not necessarily visible to
another user.
● When a Unisphere Central user adds a Storage Center, he or she must provide credentials for a Storage Center user.
The privilege level and user groups assigned to the Storage Center user determine the access that is allowed on the Data
Collector.
● The first time you add a Storage Center to the Data Collector, you must specify a Storage Center user account that has the
Administrator privilege. When you subsequently add the Storage Center for other Unisphere Central users, you can specify
Storage Center user accounts of any privilege level.
● If yourUnisphere Central user account has the Reporter privilege, you must specify a Storage Center user account that has
the Reporter privilege.
NOTE:
A Unisphere Central Administrator can also use the Data Collector to grant Storage Center access to a
Unisphere Central user with the Reporter privilege.
● Manage a Storage Center using one Data Collector only. Issues can occur if a Storage Center is managed by multiple Data
Collectors.
Storage Center User Privileges and User Groups
Storage Center groups determine which storage objects can be viewed by the Storage Center user, and the privilege level
defines what the user can do.
NOTE:
Storage Center user privileges and Unisphere Central user privileges share the same names, but they are not the
same. Storage Center user privileges control access to Storage Center functionality, and Unisphere Central user privileges
control access to Unisphere Central functionality. A user may have a different role in Unisphere Central than in Storage
Center. This role difference affects small details of that user’s access.
