1. ### Configuring the Node State Manager The following procedure describes how to configure the Node State Manager in the `network.conf` file. #### To Configure the Node State Manager In the `machine.conf` file, do the following: Add a dedicated NIC to the master-eligible nodes. Assign the `role` NSM to the dedicated NIC. For example:
       ELEMENT nic nic2@peerNode1 device qfe0
               type PHYSICAL class SECONDARY role NSM
               USE ip external-access
2. In the `network.conf` file, define the associated address and the related network. This address must be configured as a floating address in the `network.conf` file, for example:
       ELEMENT network external type IPV4 number 129.157.201.0 netmask 255.255.255.0

       ELEMENT ip external-access address 129.157.201.10 type FLOATING
               BELONG_TO network external
3. In the `cluster.conf` file, configure the cluster domain.
       ELEMENT domain cluster_domain id 100
               INVOLVE network phys-A
                       network phys-B
                       network cgtp
                       network external
               USE ip master-cgtp
                   ip master-nic0
                   ip master-nic1
1. ### Configuring a Switch The following procedure describes how to configure a switch in the `network.conf` file. #### To Configure the Switch Add the configuration element `switch` in the `machine.conf` file. Add the port elements with their connections to the NICs on the board in the `machine.conf` file. In the `network.conf` file, add the IP addresses of the switches. The IP addresses of the switches may be on a different subnet to the three CGTP subnets. In this case, add the subnet to the cluster domain definition in the `cluster.conf` file and to the `network.conf` file. ### Reconfiguring the Disk Controller Type If your prototype machine does not have exactly the same specification as your target cluster machine, you may need to reconfigure the disk controller type. #### To Reconfigure the Disk Controller Type In the configuration element `disk`, change the device parameter value. ### Configuring the Boards and NICs According to the Diskless Node Boot Policy The following procedure describes how to configure the boards and NICs in the `network.conf` file, according to the diskless node boot policy. #### To Configure the Boards and NICs According to the Diskless Node Boot Policy For the `STATIC_CLIENT_ID_POLICY` boot policy, configure the `clientId` parameter in the configuration element `board`. For the `MAC_ADDR_POLICY` boot policy, configure the Ethernet address in the configuration element `nic` for the two physical NICs. ## Adding Cluster-Specific Configuration Data to the `cluster.conf` File This section describes how to add cluster-specific network data to the `cluster.conf` file. You can define the node IDs in the `cluster.conf` file if you did not do so in stage 1. For more information, see the `cluster.conf`(4) man page. ### To Configure the Floating Address Triplet In the `cluster.conf` file, configure the floating address triplet. The floating address triplet must be a CGTP address named `master-cgtp`, and two IP addresses associated to the two physical networks. In the following program listing, `id` is the ID of the CMM domain.
       # Cluster domain definition
       #
       # id -> CMM domainId
       # ip -> master master-nic0 master-nic1 floating addresses
       #
       ELEMENT domain cluster_domain id 100
               INVOLVE network phys-A
                       network phys-B
                       network cgtp
                       network external
                       router default-router
               USE ip master-cgtp
                   ip master-nic0
                   ip master-nic1
2. Ensure that the floating address triplet is defined in the `network.conf` configuration file. For example:
       #
       # Master floating addresses
       #
       ELEMENT ip master-cgtp address 10.101.3.1 type FLOATING alias master
       	BELONG_TO network cgtp

       ELEMENT ip master-nic0 address 10.101.1.1 type FLOATING
       	BELONG_TO network phys-A

       ELEMENT ip master-nic1 address 10.101.2.1 type FLOATING
       	BELONG_TO network phys-B
4. ## Configuring the Bitmap Partitions The SMCT automatically configures the bitmap partitions to write updates to memory. The information thus stored in memory is written to the disk when the node is shut down. However, you also have the option writing the updates to the disk directly. When an update is made to a mounted directory, the update is stored on the disk in the bitmap partition. To change the way the bitmaps are configured, perform the following procedure. ### To Change the Configuration of Bitmap Partitions Log in to the build server. Copy the following files from the `/opt/SUNWcgha/nhsmct/etc/services/` directory to your smct-config-dir`/services` directory: `sndr.conf.sh` `config.NHAS_MASTER_ELIGIBLE.SPARC.SOLARIS` Change to the smct-config-dir`/services` directory. Edit the smct-config-dir`/services/sndr.conf.sh` file: Replace the following line:
       /usr/bin/sed -e "s,rdc_bitmap_mode=0,rdc_bitmap_mode=2," > $RDC_CONF
   With the following line:
       /usr/bin/sed -e "s,rdc_bitmap_mode=0,rdc_bitmap_mode=1," > $RDC_CONF
5. Edit the smct-config-dir`/services/config.NHAS_MASTER_ELIGIBLE.SPARC.SOLARIS` file: Replace the line:
       location 'file:/NHAS_PROD_DIR/nhsmct/etc/services/sndr.conf.sh'
   With the line:
       location 'file:/smct-config-dir/services/sndr.conf.sh'
