## 6.2.2 Configuring a single node cluster 

Before you begin this procedure, ensure that all of the tasks that are described in 6.1, “Configuration prerequisites” on page 96 are met. Figure 6-2 shows an illustration of a single-node configuration that is described in this section.

The steps in this section must be performed only on one node of an IBM Spectrum Archive EE cluster environment. If you plan to have only one IBM Spectrum Archive EE node, this is a so-called single-node cluster setup. 

If you plan to set up a multi-node cluster environment for IBM Spectrum Archive EE, this configuration mode must be performed once, and only on a node of your choice of your cluster environment. All other nodes must be added. To do so, see 6.2.3, “Configuring a multiple-node cluster” on page 110. 

To configure a single-node cluster for IBM Spectrum Archive EE, complete the following steps: 

1. Log on to the operating system as a root user. 

2. Start GPFS (if it is not already started) by running the following command: 

# mmstartup -a 

3. Mount the GPFS file system (if it is not already mounted) by running the following command: 

# mmmount all 

4. Start the IBM Spectrum Archive EE configuration utility with the -m CLUSTER  option by running the following command and answering the prompted questions: 

# ltfsee_config -m CLUSTER
