      1.  
        About troubleshooting Storage Foundation for Databases (SFDB) tools

"VCS: 10622 local configuration missing" and "VCS: 10623 local configuration invalid"

These two messages indicate that the local configuration is missing or that it is invalid.

The recommended action for each message is the same. Start the VCS engine, HAD, on another system that has a valid configuration file. The system with the configuration error pulls the valid configuration from the other system.

Another method is to install the configuration file on the local system and force VCS to reread the configuration file. If the file appears valid, verify that is not an earlier version.

Type the following commands to verify the configuration:

# cd /etc/VRTSvcs/conf/config
# hacf -verify .
