I'm not sure that custom macros are evaluated at the command level?  
Perhaps set your command_line to pull in the variable from the service:

define service {
     name NA_SnapMirror
     check_command netapp_snapmirror!$_SERVICEnavolume$
         use  GenericService_Core
     normal_check_interval 1000
     max_check_attempts 300
     register 0
     contact_groups CoreServers
}

define service {
     use NA_SnapMirror
     _navolume myvolumename
     service_description SnapMirror_groups
     hosts myhostname
}

define command {
     command_name  netapp_snapmirror
     command_line $USER1$/check_naf.py -H $HOSTADDRESS$ -C $USER8$  
snapmirror,$HOSTNAME$:$ARG1$,$USER25$
}

...
Alternately, if you have enable_environment_macros=1 in nagios.cfg, you 
could instead put "$NAGIOS__SERVICEnavolume" and pass the reference to 
the script.

One of the two should work for you.  If not, then I'd recommend 
restarting in debug mode, debug_level=18 will get you debug information 
about both the configuration load process, and the service check 
execution, so you should be able to figure out the problem - just fire 
it up in a reduced config set, so you only have this in there and don't 
get spammed by normal operations.

What version, btw?
