Assuming that you mean that you want to terminate this code by returning $FATAL if one or more of the files mentioned in your if statement tests are not both readable and writeable, you probably want to change:
Code:
if [[ ! -r $MMREJ ] && [ ! -w $MMREJ ] ||[ ! -r $MMIN ] && [ ! -w $MMIN ] || [ ! -r $MMLOG ] && [ ! -w $MMLOG ]];then       
	return ${FATAL}

to something more like:
Code:
if [ ! -r "$MMREJ" ] || [ ! -w "$MMREJ"  ] || \
   [ ! -r "$MMIN" ] || [ ! -w "$MMIN" ] || \
   [ ! -r "$MMLOG" ] || [ ! -w "$MMLOG" ]
then	return "${FATAL}"
fi

Note, also, that none of the variables this script is using have been defined by anything you have shown us. If they aren't defined before they are used, the chances of any of this working are pretty small.

set_directory_epoch

set directory to new epoch(1m)											    set directory to new epoch(1m)

NAME

       set directory to new epoch - Reconstructs a directory's replica set, allowing you to designate a new master replica or to exclude a replica

SYNOPSIS

       cdscp set directory directory-name to new epoch master clearinghouse-name [readonly clearinghouse-name...]  [exclude clearinghouse-name...]

ARGUMENTS

       The  full  name	of the directory.  The full name of the clearinghouse in which an individual replica is located.  The first clearinghouse-
       name specifies where the master replica is stored.

DESCRIPTION

       The set directory to new epoch command reconstructs a directory's replica set, allowing you to designate a new master replica or to exclude
       a  replica.   You must list each existing replica and indicate whether an existing replica needs to be included in or excluded from the new
       replica set.  You can include or exclude more than one replica.	The ellipses (...)  indicates that you can specify multiple  clearinghouse
       names, separated by spaces.

       When you set a new epoch on a directory, you must disable the clearinghouse containing the replica that is being excluded.  To do this, use
       the disable server command (if the server has more than one clearinghouse, all its clearinghouses will be disabled). Note that  all  clear-
       inghouses that are not excluded must be enabled and available before you issue the disable server command.

   Privilege Required
       You  must  have administer permission to the directory, and the server principal needs administer, read, and write permission to the direc-
       tory.  When designating a new master replica, you also need write permission to the clearinghouse that stores the new master  replica,  and
       the server principal needs write permission to each clearinghouse where the replica type is changed to read-only.

NOTE

       This command may be replaced in future releases by the dcecp command, and may no longer be supported at that time.

EXAMPLE

       The  following command sets a new epoch for the directory /.:/mfg.  The master replica is in the clearinghouse /.:/Paris1_CH, and read-only
       replicas are in the clearinghouses /.:/Chicago1_CH, /.:/Seattle_CH, and /.:/NY1_CH.  The new replica set excludes the replica in the clear-
       inghouse  /.:/NY1_CH.   cdscp>  set directory /.:/mfg to new epoch master /.:/Paris1_CH  > readonly /.:/Chicago1_CH /.:/Seattle_CH exclude
       /.:/NY1_CH
