Disconnecting the Active and Standby Servers

Disconnecting the Active and Standby Servers

This section describes how to disconnect the active and standby servers so that they cannot form an HA system.

Prerequisites

  • The installation directory has sufficient available space. In the SUSE Linux operating system, you can run the df -hk /opt command to view the available space of the /opt directory.
  • The HA system is in normal state.
  • Data has been synchronized between the active and standby servers.
  • In a local two-node cluster, ensure that the floating IP address is online.

Procedure

  1. Log in to the active server as the root user and run the following command to query the NMSServer resource status:

    NOTE:

    If the SUSE Linux operating system has been hardened, log in to eSight as the ossuser user and then switch to the root user.

    # hares -state NMSServer -sys Host name of the server

    If ONLINE is displayed in the command output, go to 5. Otherwise, go to 2.

  2. Run the following command to bring the AppService resource group of the active server offline:

    # hagrp -offline AppService -sys Host name of the active server

    NOTE:

    Run the following command to query the AppService resource status. Perform subsequent operations after ensuring that the resource status is displayed as OFFLINE:

    # hagrp -state AppService -sys Host name of the active server

  3. In a local two-node cluster, run the following command to bring the FloatIP resource of the active server online:

    # hares -online FloatIP -sys Host name of the active server

  4. Start the eSight maintenance tool process on the active server.

    1. Run the following command to connect to the file system:

      # mount /dev/vx/dsk/datadg/lvfiledata /opt/eSightSync/

    2. Run the following commands to start the eSight maintenance tool:

      # su - ossuser

      # cd /opt/eSight/mttools/bin

      # ./start-sysmon-ha.sh

  5. Log in to the eSight maintenance tool of the active server from a client.

    • Log in to the eSight maintenance tool using Internet Explorer.
      1. Open Internet Explorer.
      2. Enter https://Server IP address:31945 in the address box and press Enter.
      3. Enter the user name sys and its password. Then, click Log In.
        NOTE:

        The maintenance tool provides only one user name sys, and the initial password of the sys user is Changeme123.

    • Log in to the eSight maintenance tool using Firefox or Chrome.
      1. Enter https://Server IP address:31945 in the address box and press Enter.
      2. Enter the user name sys and its password. Then, click Log In.
        NOTE:

        The maintenance tool provides only one user name sys, and the initial password of the sys user is Changeme123.

  6. Choose HA Management > HA Deployment from the main menu.
  7. Select Split.
  8. Click Apply.

    In the Confirm dialog box that is displayed, click Yes to disconnect the active and standby servers. If the message "Succeeded" is displayed, the active and standby servers are disconnected successfully.
