ProcedureTo Install the Daemon Monitor

  1. As superuser, install the following Daemon Monitor packages on each master-eligible node:

    # pkgadd -d /NetraHASuite/Packages/ SUNWnhpma SUNWnhpmb SUNWnhpms \
    SUNWnhpmn SUNWnhpmm

    For a description of the Daemon Monitor, see the Netra High Availability Suite Foundation Services 2.1 6/03 Overview.

ProcedureTo 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.

  1. 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

  2. As superuser, install the Watchdog Timer package on each master-eligible node:

    # pkgadd -d /NetraHASuite/Packages/ SUNWnhwdt

    The Watchdog Timer can be configured differently on each node depending on your needs. See Configuring the nhfs.conf File.

ProcedureTo 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

  1. Go into the Foundation Services patch directory:

    # cd /NETRAHAS/Patches

  2. 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

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.

Examples in these procedures use IPv4 Class C addresses.

ProcedureTo Create the IP Addresses for the Network Interfaces

  1. Log in to each master-eligible node as superuser.

  2. 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.

ProcedureTo 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.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. Create a /etc/netmasks file with a netmask of 255.255.255.0 for all subnetworks in the cluster.
