You can start, shut down, and restart local, remote, or multiple Linux/UNIX hosts. Find information on each of these options.
Log on with root permissions and rsh on all hosts in the cluster. To start a hosts specified by name, you need to be able to run rsh across all hosts in the cluster without having to enter a password; see your operating system documentation for information about configuring rsh.
Starting hosts brings them into the cluster where they become usable resources.
By default, all hosts that join the cluster remain in the cluster, even if they become unusable.
Optionally, after a period of time in the Unavailable state, a compute host can expire from the cluster—it no longer appears in the Console, or in egosh resource list or resource view output, and it is not affected by egosh start all or restart all commands.
Host expiry is not irreversible. If you restart an expired host (for example, run egosh ego start host_name or restart the expired host while automatic system startup is configured), it can rejoin the cluster in the same way that a newly installed host joins the cluster.
If you want to remove a management host from the cluster, a different procedure is required.
To configure the host expiry feature, take the following steps.
