Bring up the node.

To bring up the node

  1. Restart Node A.
  2. Log in as superuser.
  3. Make the VCS configuration writable.
    # haconf -makerw
  4. Display the service groups currently configured.
    # hagrp -list
  5. Freeze the service groups.
    # hagrp -freeze group -persistent

    Repeat this command for each service group in step 4.

  6. Make the configuration read-only.
    # haconf -dump -makero
  7. Stop VCS on Node A.
    # hastop -local -force
  8. Edit the VCS system configuration file /etc/sysconfig/vcs as follows:

    Change the line:

        ONENODE=yes

    To:

        ONENODE=no
  9. Enable the GAB and LLT startup files so they can be used.
    # mv /opt/VRTSgab/gab.old /opt/VRTSgab/gab
    # mv /opt/VRTSllt/llt.old /opt/VRTSllt/llt
