Symphony cluster startup process

When the administrator starts the cluster using the egosh ego start all command, the processes in the cluster are started as shown below:

  1. The lim is started on the master host.

  2. The master lim starts both pem and vemkd on the master host, and lim on all compute hosts.

  3. vemkd starts egosc.

  4. egosc starts sd (session director), rs. plc, purger, and wsm using pem.

  5. sd starts ssm.

  6. lim on each compute host starts pem on the same host, and reports information to the master lim.

  7. ssm starts sim on a compute host (upon a request for resources from a client).

  8. sim starts si.
