Cluster management tasks (Linux)

Start EGO on the Linux cluster

Log on with root permissions. Ensure rsh is available on each host in the cluster.

Important:

By default, only root can start, stop, or restart the cluster. Optionally, you can grant root privileges to egoadmin, the cluster administrator account. See Planning and Installing Your EGO Cluster on Linux for details.

Start EGO on all Linux hosts in the cluster:

egosh ego start all

Shut down EGO on the Linux cluster

Log on as egoadmin or root to any host in the cluster.

Note:

If the master is down, log on to a management host (if the master is down, there is no way to get the complete list of cluster services and daemons; on the management host, the cluster file and hostcache file lists this information).

  1. Log on to EGO as a cluster administrator:

    egosh user logon -u user_name -x password

    For example, type

    egosh user logon -u Admin -x Admin

  2. Shut down all EGO services and daemons on all Linux hosts in the cluster:

    egoshutdown.sh

Restart EGO on the Linux cluster

Log on with root permissions on the local host. Assuming the master is up, logon to any host in the cluster.

Note:

If the master is down, log on to a management host (if the master is down, there is no way to get the complete list of cluster services and daemons; on the management host, the cluster file and hostcache file lists this information).

Restart EGO:

egosh ego restart all

EGO restarts on all hosts in the cluster (including Windows hosts if you have a mixed cluster). Services are not restarted with this command.
