4.2 Exemplary Configuration for Servicing Two NFS Jobs

  1. Drawing of network connection for two NFS jobs:



  2. Basic information about the exemplary network machines:

    In this example, there are two connected network machines respectively named "peter"
    and "russell." The following table provides the information about them that you can see
    from the "russell" machine in its /etc/hosts.

127.0.0.1...............localhost
#
# local interfaces
192.9.2.2................... russell
..........loghost
192.9.3.2....................russell-1
#
# Other HA server interfaces
192.9.2.1.................... peter
192.9.3.1.................... peter-1
#
# HA Active interfaces
192.9.3.9.................... act1
192.9.2.9.................... act0
#
# PCNFS client
192.9.3.10...................client

The next table provides the information about them that you can see from the "peter" machine in its /etc/hosts.


127.0.0.1...............localhost
#
# local interfaces
192.9.2.1....................peter ..........loghost
192.9.3.1....................peter-1
#
# Other HA server interfaces
192.9.2.2....................russell
192.9.3.2....................russell-1
#
# HA Active interfaces
192.9.3.9....................act1
192.9.2.9....................act0
#
# PCNFS client
192.9.3.10..................client

The next table provides the information about them that you can see from the client machine in its /etc/hosts.


127.0.0.1...............localhost
#
192.9.3.10....................client.....loghost
192.9.2.10....................client-1
# HA Active interfaces
192.9.3.9......................act1
192.9.2.9......................act0

Notes:
  1. To access the two jobs provided on the server, the client machine must first
    mount the partitions information on its hard disk.
  2. The line "SUPPORT=NFS" should be in the configuration.
  3. When servicing an NFS job, the major device number and minor device number
    viewed from both the "peter" and "russell" machinese must be the same. To ensure
    the numbers are the same for both machines, place in the same slot position the
    second SCSI cards used to connect both machines to the shared disk.
  4. It is recommended to set in the configuration the SYNC_DISK_TIME at
    5 seconds for an NFS job.
