Defining a Machine Group

Machine groups can be defined to collect multiple clients in a common target for NIM operations. Groups can be defined for standalone, diskless, or dataless clients; but a group can only contain clients of a single type.

In the Web-based System Manager NIM application, machine groups are not explicitly created and managed, but ad hoc groupings are supported by multi-selecting the icons representing machines in the NIM container. Once selected, a group of machines can be administered by selecting an action from the Selected menu. Note: You can only perform most operations on multi-selected machines of the same type.


  1. To define a machine group, enter the smit nim_mkgrp fast path.
  2. Select the type of group you want to define.
  3. Enter the name of the group and member information.

From the Command Line

To define a machine group, enter:

nim -o define -t mac_group -a add_member=MemberName GroupName

For example, to create a machine group named MacGrp1 containing previously defined machines Standalone1 , Standalone2 , and Standalone3 , enter:

nim -o define -t mac_group -a add_member=Standalone1 \
-a add_member=Standalone2 -a add_member=Standalone3 \
-a comments="Machines for Department d03" MacGrp1
