ExtremeWare EPICenter Software Installation and User Guide 8-3
• TheHostsandUsersgroups(eitherthepredefinedgroupsorsubordinategroups)may
be used bytheoptional Policy Manager. This is also true ofall user-definedgroups. No
other EPICenter applets currently support groups of these types.
In a group that contains resources of different types, the Policy Manager will ignore
those resources that are not relevant to the purpose for which the group has been
selected.
Theothertwopredefinedgroups,theDeviceGroupsgroup and the ImportSourcesgroup,
are restricted in the way they can be used.
Device Groups. The“DeviceGroups”groupcontainsthedevicegroupsanddevices
known to the EPICenter inventory database. Device groups are created within the
EPICenter Inventory Manager applet, and devices are added or discovered, and are
assigned to device groups, within that applet. All port resources are also defined in
association with the devices known to the Inventory Manager.
• You cannotadd resources to or remove resources from the Device Groups group
through the Grouping Manager.
• You can add resources that are children of Device Groups group—device groups,
devices, and ports—as members (children) of other groups.
Import Sources. The Import Sources group is used to contain resources imported from
an external source, such as a file, NT Domain Controller, or LDAP directory. When you
perform an import operation, the Grouping Manager creates a new group under the
Import Sources group, and puts all the imported resources under that group.
• You cannot addgroups or individualresources as childrenof theImport Sourcesgroup
except by using the Import function.
• You cannot remove any of the members (including sub-groups) of an imported group.
The imported group can only be deleted in its entirety, using the Destroy function.
• You can add resources that are children of an Import Sources group as members
(children) of other groups.
