IBM Tivoli Monitoring, Version 6.3 Fix Pack 2


Gathering cluster nodes information


Before defining the Base cluster, you must have the following information available:


Procedure

  1. The host names of both cluster nodes, such as:

    • node1

    • node2

  2. In order to set up Tivoli Monitoring with Tivoli System Automation for Multiplatforms, you will need two cluster nodes with at least 1 NIC (Network Interface Card) in each computer.

    For a more robust cluster, use two NICs for each computer, so that the Tivoli System Automation for Multiplatforms heartbeat function has a failover path, in case one of the NICs goes down. The NICs you use for System Automation for Multiplatforms must be on the same subnet.

    You will need the host names of the NICs. It is not necessary to have these host names defined in the domain name system, they only need to be defined in the local host table of each node.

  3. The mount point name of the shared file system - must be the same on both nodes (and mounted only on one node), such as:

    /shareddisk

  4. The device name of the shared disk which is mounted to that mount point – it also must be the same on both nodes, such as:

    /dev/sdc1

    • During testing on Red Hat Enterprise Linux, the Logical Volume Manager was used to define the shared disk. The following syntax was used for the device name (only for shared drives created with the Logical Volume Manager):

      /dev/mapper/volume_group_name-lv_name

      Where volume_group_name is the name of the volume group containing the shared disk logical volume, and lv_name is the name of the logical volume. For example: if the volume group name is shared_vg and the logical volume name is shared_lv, the device name would be:

      /dev/mapper/shared_vg-shared_lv

    • On AIX, the following syntax was used for the device name:

      /dev/lv_device_name

      If the logical volume device name is datalv, the device name would be:

      /dev/datalv

  5. The type of the file system on the shared disk, such as:

    • For Linux: reiserfs

    • For AIX: jfs2

  6. The virtual IP address and netmask (must be in the same subnet as the real IP addresses)

  7. The Ethernet numbers of the public network interfaces of both nodes, which will host the virtual IP address, such as:

    • Run Linux: eth0

    • Run AIX: en1

    (Run the ifconfig command to determine the Ethernet numbers)
