Description

Error Message

After upgrade, llt tries to start. This should not happen when using one node VCS cluster.

 

Solaris:

To start VCS as one node, make sure llt/gab  are disabled. Setup the SMF service correctly for the next reboot by running the following :


# svcadm disable llt
# svcadm disable gab
# svcadm disable vcs

# svcadm enable vcs-onenode

If the vcs-onenode SMF service is not found then create the vcs-onenode SMF service :
# svccfg import /etc/init.d/vcs-onenode.xml
# svcadm enable vcs-onenode

 

Linux:

To configure VCS in single node mode

  1. Edit the following file to change the value of the ONENODE environment variable to yes.

    /etc/sysconfig/vcs

  2. If the single node is intended only to manage applications, you can disable LLT, GAB, I/O fencing kernel modules.

    Note:Disabling VCS kernel modules means that you cannot make the applications highly available across multiple nodes.

 

 

Cause

Installer fails to create vcs-onenode  service after upgrade OR cluster was not configured as single node.
