In a SFCFS environment currently (for SFCFS versions up to 5.0MP3) the VCS node names (specified in /etc/llthosts) must be the same as the OS host names (obtained from the hostname command).   CVM will not start if the VCS node names are different from the OS host names. The following is error message from vxclustadm when the CVM cluster is started.

# hostname
sydfire01XX

# lltstat -H
sydfire01

# vxclustadm -m vcs -t gab startnode
VxVM vxclustadm ERROR V-5-1-9702 Node sydfire01XX not found in /etc/VRTSvcs/conf/config/main.cf

Please make sure that the VCS node names are the same as the OS host names.

AIX has the Object Data Manager (ODM) an internal data base for system information. The hostname in the ODM can be different to the name returned by the command “hostname”. The way to the check the server name in the ODM is very the system administration menu, “smitty”.

This is how to check the server name, firstly run the command, “smitty”. Then choose “Communications Applications and Services”, then choose “TCP/IP”, then select “Further Configuration”,  then choose “Hostname” and finally, select “Set the Hostname”, the server name stored in the ODM will be displayed on the right hand side.

Ensure the name stored in the ODM is the same as the name used in VCS.
