The uuidconfig command line utility can display, configure, and unconfigure the UUID (universally unique id) on the cluster nodes.
Configures the cluster UUID on the nodes that are specified based on whether a cluster UUID exists on any of the VCS nodes:
-rsh Uses the communication protocol rsh (remsh on HP-UX) instead of the default ssh. -clus Indicates the operations to configure, unconfigure, display, or copy the UUID are for the VCS cluster. -configure [-force] [-use_llthost | sys1 [sys2...]
o If no cluster UUID exists or if the cluster UUID is different on the cluster nodes, then the utility does the following: * Generates a new cluster UUID using the /opt/VRTSvcs/bin/osuuid.
* Creates the /etc/vx/.uuids/clusuuid file where the utility stores the cluster UUID.
* Configures the cluster UUID on all nodes in the cluster.
o If a cluster UUID exists and if the UUID is same on all the nodes, then the utility retains the UUID. Use the -force option to discard the existing cluster UUID and create new cluster UUID.
o If some nodes in the cluster have cluster UUID and if the UUID is the same, then the utility configures the existing UUID on the remaining nodes. The -use_llthost option indicates that the utility must use the system names from the /etc/llthosts file. -unconfigure [-use_llthost | sys1 [sys2...] Unconfigures the cluster UUID from all the nodes and removes the /etc/vx/.uuids/clusuuid file. The -use_llthost option indicates that the utility must use the system names from the /etc/llthosts file.
-display -use_llthost | sys1 [sys2 sys3...] Displays the cluster UUIDs on all the nodes. The -use_llthost option indicates that the utility must use the system names from the /etc/llthosts file.
-copy -from_sys sys -to_sys sys1, [sys2...] Copies the cluster UUID from a system that is specified using the -from_sys option to all systems that are specified using the -to_sys option.
/etc/llthosts LLT configuration file with a list of all the nodes in the cluster.
/etc/vx/.uuids/clusuuid File where VCS stores the cluster UUID.
