1. ### To Install the Daemon Monitor As superuser, install the following Daemon Monitor packages on each master-eligible node:
       # pkgadd -d /NetraHASuite/Packages/ SUNWnhpma SUNWnhpmb SUNWnhpms \
       SUNWnhpmn SUNWnhpmm
2. For a description of the Daemon Monitor, see the Netra High Availability Suite Foundation Services 2.1 6/03 Overview. ### To Install the Watchdog Timer Install and configure the Watchdog Timer provided with the Foundation Services only if you are using Netra servers that have hardware watchdogs at the LOM level. For a list of the types of watchdogs for different Netra servers, see the Netra High Availability Suite Foundation Services 2.1 6/03 Hardware Guide. If you are using Netra servers with hardware watchdogs at the OBP level, do not install the Watchdog Timer provided with the Foundation Services. These hardware watchdogs are monitored by the server's software. Before installing the Watchdog Timer, do the following: Check that the `SUNWnhcdt` package is already installed on each master-eligible node. For more information, see To Install the Cluster Membership Manager. Check that the following LOM driver packages are installed: `SUNWlomr` `SUNWlomu` As superuser, install the Watchdog Timer package on each master-eligible node:
       # pkgadd -d /NetraHASuite/Packages/ SUNWnhwdt
1. The Watchdog Timer can be configured differently on each node depending on your needs. See Configuring the `nhfs.conf` File. ### To Install Service Enhancements A number of service enhancements are available in the Foundation Services patches. The service enhancements include: Reduced Duration of Disk Synchronization Data Management Policy Masterless Cluster Sanity Check of Replicated Slices Delayed Synchronization Serialized Slice Synchronization Tool to copy local files from the master node to the vice-master node Go into the Foundation Services patch directory:
       # cd /NETRAHAS/Patches
Consult the README file in each Foundation Services patch for information about the patches you must install and instructions about how to install them. ## Configuring the Master-Eligible Node Addresses Before assigning IP addresses to the network interfaces of the master-eligible nodes, see "Cluster Addressing and Networking" in the Netra High Availability Suite Foundation Services 2.1 6/03 Overview. In the Foundation Services, three IP addresses must be configured for each master-eligible node: An IP address for the first physical interface, NIC0, corresponding to the first network interface. This interface could be `hme0`. An IP address for the second physical interface, NIC1, corresponding to the second network interface. This interface could be `hme1`. An IP address for the virtual physical interface, `cgtp0` The virtual physical interface should not be configured on a physical interface. The configuration is done automatically when you configure Reliable NFS. For more information about the `cgtp0` interface, see the `cgtp`(7D) man page. The IP addresses can be IPv4 addresses of any class with the following structure:
    network_id.host_id
2. When you configure the IP addresses, make sure that the node ID, nodeid, is the decimal equivalent of host_id. You define the nodeid in the `cluster_nodes_table` file and the `nhfs.conf` file. For more information, see Configuring the Foundation Services on the Master-Eligible Nodes. The following procedures explain how to create and configure IP addresses for master-eligible nodes. To Create the IP Addresses for the Network Interfaces To Update the Network ID Files To Configure External IP Addresses Examples in these procedures use IPv4 Class C addresses. ### To Create the IP Addresses for the Network Interfaces Log in to each master-eligible node as superuser. In the `/etc/hosts` file on each master-eligible node, add the three IP addresses, followed by the name of each interface.
       10.250.1.10     netraMEN1-nic0
       10.250.2.10     netraMEN1-nic1
       10.250.3.10     netraMEN1-cgtp

       10.250.1.20     netraMEN2-nic0
       10.250.2.20     netraMEN2-nic1
       10.250.3.20     netraMEN2-cgtp
In the rest of this book, the node `netraMEN1` is the first master-eligible node. The first master-eligible node is the node that is booted first after you complete installing the Foundation Services. The node `netraMEN2` is the second master-eligible node that is booted after the first master-eligible node has completed booting. ### To Update the Network ID Files In the `/etc` directory on each master-eligible node, you must create a `hostname` file for each of the three interfaces. In addition, update the `nodename` and `netmasks` files. Create or update the file `/etc/hostname.`NIC0`` for the NIC0 interface. This file must contain the name of the master-eligible node on the first interface, for example, `netraMEN1-nic0`. Create or update the file `/etc/hostname.`NIC1`` for the NIC1 interface. This file must contain the name of the master-eligible node on the second interface, for example, `netraMEN1-nic1`. Create or update the file `/etc/hostname.cgtp0` for the `cgtp0` interface. This file must contain the name of the master-eligible node on the `cgtp0` interface, for example, `netraMEN1-cgtp`. Update the `/etc/nodename` file with the master-eligible node's IP address. If you have installed CGTP, add the name set on the CGTP interface, for example, `netraMEN1-cgtp`. If you have not installed CGTP, add the name set on the NIC0 interface, for example, `netraMEN1-nic0`. Create a `/etc/netmasks` file with a netmask of `255.255.255.0` for all subnetworks in the cluster.
