Fabric Configuration
This section contains an example topology and an example set of nodes. The example configuration (FIGURE 5) contains four nodes and a switch. The key step is the creation of the .xml file. The example file uses password for the string you should use to substitute a password. The following example has two compute nodes and four switches. The names of the compute nodes are: sc1 and sc2. The switch nodes are greatsandy, greatbasin, dryvalley, and saltflats. This section contains the steps and configuration file to create a single partition called part1.
To Configure the Fabric
The following example configures a fabric using the FM command-line tools.
Type the following command to switch to the fmadmin role.
Type the following command to configure the fabric:
If you are not using RBAC, skip this step.
# su fmadmin
# create_fabric sfl
NOTE
Fabric sfl was created when you followed the configure fabric procedures in "Building Secure Sun Fire Link Interconnect Networks Using Midframe Servers."

Note that the .xml file contains password strings and should only be placed in a secure directory. You must be very careful with this file.
