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 environment, 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:

    # 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

    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. Run the following command to bring the FloatIP resource online on the active server:

    # 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. 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 Firefox or Chrome.
      1. Enter https://Floating IP address of the eSight server:31945 in the address box and press Enter.

        If a message indicating an issue with the website security certificate is displayed, see What Do I Do If eSight Displays a Security Certificate Error During Login.

      2. Enter the user name sys and its password. Then, click Log In.

        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.

  9. Click Close.
