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: # mmstartup -a # mmmount all # ltfsee_config -m CLUSTER 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: 3. Mount the GPFS file system (if it is not already mounted) by running the following  command: 4. Start the IBM Spectrum Archive EE configuration utility with the  -m CLUSTER  option by  running the following command and answering the prompted questions: 106  IBM Spectrum Archive Enterprise Edition V1.2.6: Installation and Configuration Guide IBM Spec trum Scale Cluster IBM Spectrum Archiv e EE Cluster EE Node Group 1 IBM  Spectrum  Scale EE Control Node 1 F F Ethernet GPFS Native Client IBM Spectrum Scale Client GPFS Native Client CIFS/SMB Client GPFS Native Client NFS Client GPFS Native Client FTP Client Pool 2 Pool 1 D D T1 T2 T3 T4 T5 Free Tapes Library SAN or  shared NSD access IBM Spectrum Archive Node Tape Library (logical)  F Fibre Channel or SAS Port D Tape Drive Tape Cartridge SAN Connection Network Connection Disk or Flash Storage Legend Tape Drive Connection Figure 6-2 IBM Spectrum Archive single-node configuration
