Description

ha.sh script proposed improvements :

• Remove hardcoded SIMUL and IOR paths.
• Add -p max failover period parameter.
• Add -r dry run parameter.
• Add "iozone" load.
• Add the possibilities to set the number of mpi threads per client.
• CRM is not always configured to fail target back when their primary node is back. Adds the possibility to execute failback command if required.
• The logs from other clients are also required if non mpi load fails on one client only. Dump logs from all clients.
• Sometimes it is required to:
  run ha.sh with custom ior, simul parameters;
  start only the defined list of applications and to not start other of them;
  start MPI loads instances on defined number of clients.
