HP EVA Cluster Extension Software Administrator Guide (5697-2445, July 2013)

Related information
clxevarun expects only the app_name parameter, which
uniquely identifies an application service in the APPLICATION
section of the user configuration file.
To force a DR group failover, use the forceflag option.
When using clxevarun, the forceflag option is used
instead of app_name.forceflag, which is only used with
the non-CLI version of EVA Cluster Extension.
CAUTION: The forceflag option is an emergency switch used
to manually activate your vdisk. If the forceflag option has been
specified, EVA Cluster Extension will not check any consistency or
concurrency rules before activating the vdisk in the associated DR
group.
Return codes clxevarun exits with one of the following return codes:
OK Application service can be started.0
ERROR_GLOBAL Application service could not start on any node in either
site on either EVA storage system.
1
ERROR_DC Application service could not start on any node in the local site
on the local EVA storage system.
2
ERROR_LOCAL Application service could not start on this node.3
