Renaming the LLT and GAB startup files

You may need the LLT and GAB startup files to upgrade the single-node cluster

to a multiple-node cluster at a later time.

To rename the LLT and GAB startup files

◆

Rename the LLT and GAB startup files.

# mv /etc/init.d/llt /etc/init.d/llt.old

# mv /etc/init.d/gab /etc/init.d/gab.old

Modifying the startup files

ONENODE=yes

Verifying single-node operation

After successfully creating a single-node cluster, start VCS and verify the cluster.

To verify single-node cluster

Bring up VCS manually as a single-node cluster using hastart with the

-onenode option:

# hastart -onenode

Verify that the had and hashadow daemons are running in single-node mode:

# ps -ef | grep ha

root 285 1 0 14:49:31 ? 0:02 /opt/VRTSvcs/bin/had -onenode

root 288 1 0 14:49:33 ? 0:00 /opt/VRTSvcs/bin/hashadow
