Network Installation Management Guide and Reference
Any machine in the NIM
environment can be a resource server. In simple environments, the NIM
master is usually used to serve all the NIM resources.
Defining resources on client
machines can be beneficial for the following reasons:
- Disk space limitations on the NIM master may prohibit
the storage of all the resources on a single machine.
- Resource usage may be heavy, and communications and
data access bottlenecks could occur if all the resources were served by a
For example, if you use NIM to install 200 machines on 5 different subnets,
you could have a set of resources created and available on each subnet.
Each set of resources would be used to install the machines on the same
subnet. In addition to distributing the workload among several resource
servers, this would also reduce the network traffic across the gateways
between the different subnets.
- Select the Resources container.
- From the Resources menu, select New Resources.
- Follow the wizard instructions to create the resource.
- To create a resource on a NIM client, enter the
smit nim_mkres fast path.
- Select the Resource Type.
- In the displayed dialog fields, supply the correct
values for the resource options. Be sure to specify the name of the
client machine for the Server of the Resource field. Use the help
information or the LIST option to help you. All attributes specified
when the resource is defined (such as location and
source) must be local to the server machine.
To create a resource on a NIM
client, specify the client's NIM name for the server attribute
when defining the resource.
To create an
lpp_source resource named images2 from a CD on the NIM
client machine, client_mac1, in the /resources/images
nim -o define -t lpp_source -a
-a location=/resources/images -a source=/dev/cd0 images2
