#   Name:       cl_smm_ochk
#
#   Function:   Checks to see if the 'manual' option for storage subsystem 
#               recovery has been overriden by a prior choice of 'continue'
#               in response to a split.
#
#               This function is encapsulated in this routine to avoid having
#               similar logic scattered through the various storage subsystem
#               routines.
#
#               There are two parts to this test:
#               1.  Split/merge policies have been configured so that a manual
#                   response to a split or merge applies to a subsequent choice
#                   for storage subsystem recovery.
#               2.  On a split, the manual response indicated that this 
#                   partition should continue.
#
#   Notes:      The expected use of this function is:
#                   if /usr/es/sbin/cluster/events/utils/cl_smm_ochk
#                   then
#                       #
#                       :   Perform Automatic Recovery
#                       #
#                   else
#                       #
#                       :   Perform Manual Recovery
#                       #
#                   fi
#
#               The implementation in this routine depends on the fact that 
#               'manual' is an allowed policy on split or merge only for linked
#               clusters, and hence the partitions of the clusters correspond
#               to PowerHA sites.
#
#
#   Input:      *   Configuration choices in HACMPsplitmerge
#               *   Presence/absence of tracking file /usr/es/sbin/cluster/etc/smm_oflag
#                   normally created by cl_sm_continue
#
#
#   Output:     return code = 0 - 'manual' storage subsystem recovery has been
#                                 overriden; storage subsystem recovery should
#                                 proceed as though 'automatic' had been 
#                                 configured.
#               return code = 1 - 'manual' storage subsystem recover has not been
#                                 overridden; manual recovery of the storage 
#                                 subsystem is required.
