The `nhinstall` tool checks which version of the Solaris operating system has been installed. The `nhinstall` tool also checks whether the Foundation Services are already installed on the master-eligible nodes. If the Foundation Services are already installed, the `nhinstall` tool exits and displays an error message. If you want to upgrade to the new version of the Foundation Services, see Part V, Upgrading a Cluster. Otherwise, remove the existing Foundation Services packages and restart the installation as described in Resetting the `nhinstall` Tool for a New Installation. The `nhinstall` tool then installs the Foundation Services and the CGTP packages on the master-eligible nodes. Wait 15 to 20 minutes while the Foundation Services packages and the CGTP patches are installed on the master-eligible nodes. Then, the following instructions are displayed by the `nhinstall` tool:
    Reboot the master eligible node nodeid.
    On the console of nodeid (login: root, password:), type:
        # init 6
    Wait for the console login prompt.
    Answer 'y' when it has been displayed:
2. where nodeid is the node ID. Follow these instructions by performing the following procedure. ### To Reboot the First Master-Eligible Node Log in to the first master-eligible node as superuser: Reboot the node:
       # init 6
3. When the boot is complete, type `y` at this prompt in the console window of the installation server:
       Answer 'y' when it has been displayed: y
After you type `y`, the following instructions are displayed by the `nhinstall` tool in the installation server console:
    Reboot the master eligible node nodeid.
    On the console of nodeid (login: root, password:), type:
       # init 6
    Wait for the console login prompt.
    Answer 'y' when it has been displayed:
2. where nodeid is the node ID. Follow these instructions by performing the following procedure. ### To Reboot the Second Master-Eligible Node Log in to the second master-eligible node as superuser. Reboot the second master-eligible node:
       # init 6
3. When the boot is complete, type `y` at this prompt in the console window of the installation server:
       Answer 'y' when it has been displayed: y
- After you type `y`, the `nhinstall` tool installs the software for diskless nodes on the master-eligible nodes if one of the following is true: You have defined diskless nodes in the `cluster_definition.conf` file. You did not define diskless nodes in `cluster_definition.conf`, but you answered `y` to the following question at the beginning of the installation process:
      Do you want to install the Solaris services for
      diskless nodes anyway [y/n]: y
1. In the second case, only the Solaris services for diskless nodes are installed. Wait approximately 20 minutes while the `nhinstall` tool installs the Solaris services for the diskless nodes on the master-eligible nodes. No status messages are displayed during this operation. Wait an additional 5 minutes while the `nhinstall` tool configures the Foundation Services for each diskless node. You can see the installation status on the console window of each node. The `nhinstall` tool automatically installs the Solaris packages, the Foundation Services packages, and the CGTP patches in the root directory of each diskless node. At this stage, the Solaris operating system and the Foundation Services have been installed on the nodes of the cluster. The `nhinstall` tool prompts you to reboot both master-eligible nodes and to boot the diskless nodes. For instructions, see To Reboot the Master-Eligible Nodes After the Diskless Nodes Are Configured and To Boot the Diskless Nodes. ### To Reboot the Master-Eligible Nodes After the Diskless Nodes Are Configured Reboot the first master-eligible node:
       # init 6
2. Wait until the login prompt is displayed on the first master-eligible node. To continue with the installation process, type `y` at this prompt:
       Answer 'y' when it has been displayed: y
3. Reboot the second master-eligible node:
       # init 6
4. Wait until the login prompt is displayed on the second master-eligible node. To continue with the installation process, type `y` at this prompt:
       Answer 'y' when it has been displayed: y
### To Boot the Diskless Nodes After you type `y` at the `nhinstall` prompt, the following instructions are displayed by the `nhinstall` tool:
    The software installation is complete.
    Setup the eeprom boot parameters on your diskless nodes:
    At the ok prompt, type:
      ok> setenv local-mac-address? true
      ok> setenv auto-boot-retry? true
      ok> setenv boot-device net:dhcp,,,,,5 net2:dhcp,,,,,5
      ok> setenv diag-switch? false
    You can now boot your diskless nodes.
2. To configure the boot parameters, follow this procedure. Get the `ok` prompt on the diskless node. Execute the following commands at the `ok` prompt on each diskless node:
       ok> setenv local-mac-address? true
       ok> setenv auto-boot-retry? true
       ok> setenv boot-device net:dhcp,,,,,5 net2:dhcp,,,,,5
       ok> setenv diag-switch? false
3. Boot each diskless node:
       ok> reset
While you are booting the nodes, the following information is displayed by the `nhinstall` tool:
    17:32:21 Waiting for the disks of the master-eligible nodes to synchronize.
    17:32:21   - Partitions to be replicated:
    17:32:22    . md/rdsk/d4 (2099 MB)
    17:32:22    . md/rdsk/d3 (2099 MB)
    0%....10%....20%....30%....40%....50%....60%....70%....80%....90%....100%
    17:44:18 Your cluster is ready.
This output describes the status of the initial synchronization of the disks of the master node and the vice-master node. After the diskless nodes are rebooted and after the disks are synchronized, your cluster is ready.
