[ADSM-L] Virtualfsmapping fails because of snapsure error

Greetings,
        I am running TSM 5.3.4.0 on an AIX 5.3ML5 system.  The NDMP
backup in question is to a EMC Celerra running DartOS 5.5.25-2.
        I am trying to create a virtual filesystem mapping, which gives
a new filesystem name to a subdirectory under a NAS filesystem, like so:
 
define virtualfsmapping cx02_dm2   /fs_dst_BOA    /fs_dst   /BOA
 
This command creates a new virtual filesystem name that maps to the
directory /fs_dst/BOA.  The command works:
 
01/30/08 17:17:14     ANR2017I Administrator SCHNJD issued command:
DEFINE      
                       VIRTUALFSMAPPING cx02_dm2 /fs_dst_BOA /fs_dst
/BOA       
                       (SESSION: 3848)

01/30/08 17:17:15     ANR2515I DEFINE VIRTUALFSMAPPING: A virtual file
space    
                       mapping named /fs_dst_BOA for node CX02_DM2 has
been     
                       defined. (SESSION: 3848)  
 
Then I ought to be able to issue:
 
BACKUP NODE  cx02_dm2 /fs_dst_BOA toc=y mode=full  
 
to back up just the files under that directory.  But it doesn't work, I
get a snapsure error:

When I look at the log in the Celerra, I see these messages which match.

1/30/2008 17:22 Error   NDMP    < LOG type: 2, msg_id: 0, entry:
SnapSure file system creation fails >
1/30/2008 17:22 Error   NDMP    < Look up the backupDir (/fs_dst/BOA)
failed, make sure it exists. >     
 
Is there something I have to create in the Celerra to make this work?  I
looked through the help on the Celerra itself and could not find any
reference to virtual fs mappings, but then again, the Celerra might call
them something else.  There were no hits on the TSM knowledgebase.  Any
suggestions?
