Here the global zone is part of veritas cluster and couple of zones are controlled by VCS and one zone is non-cluster.Here the root […]
Veritas cluster Agents (VCS agents)
VCS agents: VCS agent use to communicate to the HAD (high availability daemon) with all the configuration and attributes.For an example, Mount agent should be able to monitor the filesystem and able to mount/umount the filesystem according to the given commands. Agents are multi-threaded processes that provide the logic to manage resources. VCS has one agent per resource type. The agent […]
