Changing a Domain

Distributed SMIT 2.2 for AIX: Guide and Reference

Changing a Domain

The Distributed System Management Interface Tool (DSMIT) program allows you to change a domain. You can add a new client to the domain, delete a client from the domain, or redefine the domain's member list entirely. Use the chdsmitd command or the graphical interface to change a domain. When you use the interface, you can view the domain and any changes you are making to them. The Manage Domains of Machines menu provides the following options to assist in altering domains:

Show Domain Members	Displays a member list of a domain.
Add Domain Members	Adds members to a domain.
Remove Domain Members	Removes members from a domain.
Redefine Domain Members	Removes all members of a domain and adds members based on new menu selection criteria.

Prerequisite Conditions

A DSMIT server must reside on your system.

Change a Domain Using the Command Line

Enter the chdsmitd command to change a domain:
- To add a client to a domain, enter the chdsmitd -a command. You must also enter the -m flag followed by the client name and the domain name. The -a flag designates that you are adding to a domain. It does not specify the client name. Use the following format:
```
chdsmitd -a -m NewMachine Domain1
```
- To delete a client from a domain, enter the chdsmitd -s command. You must also enter the -m flag followed by the client name and the domain name. The -s flag designates that you are deleting from a domain. It does not specify the client name. Use the following format:
```
chdsmitd -s -m OldMachine Domain1
```
For further explanation of all of the chdsmitd command options, consult the chdsmitd command.
Edit the /usr/share/DSMIT/domains file by making any of the following changes:
- To add clients M1 , M2 , and M3 to the floor1 domain, enter the client names after the domain name, separating the domain and the clients with a colon. For example:
```
floor1:M1,M2,M3
```
  Note: Do not put spaces between the client names.
- To remove clients M1 and M2 from the floor1 domain, remove the clients from the line that defines the floor1 domain, leaving only the M3 client. For example:
```
floor1:M3
```

Change a Domain Using the DSMIT Interface

Select the Manage Domains of Machines option from the Domain Management menu.
Highlight the option corresponding to the change you want to make. For example, you can make specific changes such as adding or removing a domain, adding or removing domain members, or redefining a domain member list.
Note: An asterisk (*) designates fields that require input.
Once you have entered the information, press the Enter key and an output message screen appears. If you entered the information correctly, the message screen tells you that the domain has been changed. Otherwise, a message tells you if you entered an incorrect value.

Change a Domain Using the DSMIT Graphical Interface

Enter the dsmit command. A Visual System Management (VSM) application appears with machine and domain objects.
Double click on the domain object in the domain work area to show domain members.
To add domain members, drag one or more machine objects from the machines work area and drop them on the desired domain object in the domain work area.
