You can create user groups to organize users of the SAN Volume Controller cluster
by role. Roles define access to different cluster functions. Administrators
can create role-based user groups where any users added to the group
adopts the role that is assigned to that group. User groups simplify
management of user access to the cluster.
You must have the Security Administrator role to create,
delete, or change a user group.
Roles apply to both local and remote users on the cluster
and are based on the user group to which the user belongs. A local
user can only belong to a single group; therefore, the role of a local
user is defined by the single group that the user belongs to. Remote
users can belong to one or more groups; therefore, the roles of remote
users are assigned according to the groups that the remote user belongs
to.
This task assumes that you have already launched the SAN Volume Controller Console.
To create a user group, complete the following steps:
- In the portfolio, click . The Viewing User Groups panel is displayed.
- Select Create a User Group from
the task list and click Go. The Creating a
User Group panel is displayed.
- Enter a name for the user group.
- Select the role that all users adopt when they are added
to this user group. The following roles can be selected:
- Monitor
- Select this role if you want the user to access all viewing actions
available with the SAN Volume Controller Console.
This user cannot perform any actions that change the state of the
cluster or the resources that the cluster manages. The user can access
all the information-related panels and commands, back up configuration
data, change his or her password, and issue the following commands: finderr, dumperrlog, dumpinterallog,
and chcurrentuser.
- Copy Operator
- Select this role if you want the user to manage all existing FlashCopy®, Metro Mirror, and
Global Mirror relationships. They can also create and delete FlashCopy mappings, FlashCopy consistency groups,
Metro Mirror or Global Mirror relationships, and Metro Mirror and
Global Mirror consistency groups. In addition, the user can access
all the functions available to the Monitor role.
- Service
- Select this role if you want the user to view the View Clusters
panel, launch the SAN Volume Controller Console,
and view the progress of actions on clusters with the View Progress
panel, begin disk discovery process, and discover and include disks.
The user can access the following commands: applysoftware, setlocale, addnode, rmnode, cherrstate, setevent, writesernum, detectmdisk,
and includemdisk. A user with this role can also
access all the functions available to the Monitor role.
- Administrator
- Select this role if you want the user to access all functions
on the SAN Volume Controller Console and
issue any command-line interface (CLI) command, except those that
deal with managing users, user groups, and authentication.
- Security Administrator
- Select this role if you want the user to access all functions
on the SAN Volume Controller Console and
issue any CLI command. Users with this role can also manage users,
user groups, and manage user authentication.
- Select Enable this user group to be visible
to a remote authentication service if you want the user
group to match the access that is defined in user groups on a remote
authentication service. For each group of users on the remote authentication
service, there must be an SAN Volume Controller user
group with the same name and the user group must be visible to the
remote authentication service. Security administrators can control
what user groups can match the access of user groups on the remote
authentication service. When SAN Volume Controller Console authenticates
a remote user, it requests a list of groups that the user belongs
to from the remote authentication service. The system then assigns
a role to the remote user based on whether there is an existing user
group on the SAN Volume Controller with
the same name and if that user group allows remote visibility. When
these criteria are met, the SAN Volume Controller assigns
the role based on the user group role specification. If the user
is a member of multiple groups that match multiple roles, the user
is given the most powerful role. In the case where a user has a combination
of Copy Operator and Service roles, the SAN Volume Controller assigns
both roles to the user.
