caa_balance(8)
NAME
  caa_balance - Finds the optimal member for an application resource and
  relocates the resource to that member if it is not currently placed there.

SYNOPSIS
  /usr/sbin/caa_balance -all [-q]

  /usr/sbin/caa_balance resource_name [...] [-q]

  /usr/sbin/caa_balance -s source_member [-q]

OPTIONS
  -all
      Attempts to find the optimal member for all application resources on a
      cluster, one at a time.

  -s source_member
      Attempts optimal placement of all applications currently running on a
      particular member.

  -q  Supress output from the command.

DESCRIPTION
  This command evaluates the status of one or more application resources and
  relocates applications to their optimal member. The optimal member is found
  by evaluating the placement policy in the cluster at the time of execution.
  For more information on the placement policy, see caa(4).

  This command validates that an application is running on a cluster member
  that is preferred by the resource placement policy if it is currently
  running on that member.

EXAMPLES
   1.  The following example evaluates each application resource in a cluster
       for optimal placement on the cluster according to the cluster state
       and the resource profile and relocates applications to distribute
       applications more optimally among cluster members.
	    /usr/sbin/caa_balance -all
	    Resource a is already well placed
	    a is placed optimally. No relocation is needed.
	    Resource b is already well placed
	    b is placed optimally. No relocation is needed.

   2.  The following example will evaluate the plaement of the application
       resource testapp and relocate it if necessary:
	    /usr/sbin/caa_balance testapp
	    Resource testapp is already well placed
	    testapp is placed optimally. No relocation is needed.

EXIT VALUES
  The following exit values are returned:

  0   Successful completion

  non-zero
      A failure has occurred.
