Questions 22

As part of the consolidation efforts in a data center, the administrator decides to merge two two-node Veritas Cluster Server (VCS) clusters into a four-node VCS cluster. The source and target clusters are on the same networks for LLT communication. The administrator performs the following tasks as preparation for the merge while both clusters are still running:

  • modifies /etc/llttab files on the source cluster systems so the cluster ID is changed to the cluster ID of the target cluster
  • modifies /etc/llthosts files on all systems to include the four nodes
  • modifies /etc/gabtab files on all systems to require the four systems to seed
  • ensures the source cluster systems can see the fencing disks used by the target cluster
  • copies the fencing configuration files from the target cluster systems to the source cluster systems
  • adds the source cluster systems to the target cluster configuration using the hasys –add command

After the preparation is complete, the administrator stops the source cluster leaving the applications running, then stops the whole communication stack and restarts it in the correct order. When the administrator attempts to start the cluster again on the source cluster systems, they fail to join the four-node cluster.

Which preparation step that the administrator failed to perform is preventing the source cluster systems from joining the four-node cluster?

Options:

A.

The cluster needs to be manually seeded using gabconfig -x on the source cluster systems.

B.

The target main.cf file needs to be copied to the source cluster systems.

C.

The service group configuration of the source cluster needs to be applied to the target cluster.

D.

The cluster UUID from the target cluster needs to be copied to the source cluster.
