Hallo *SM'ers

The last time I saw 'InsertSlashHack' problems was on an AIX 4.3 machine
with a problem relating to large INODE blocks or similar.


This time it appears related to an 

ANS1304W Active object not found

Message.

The enviromnet is,  

TSM Server 5.2.2
AIX 5.2
Client HPUX11 dsmc 5.2.2


Look at the two following RSH initiated backup logs,

The only difference between the two commands is the trailing '/' on the
dir name passed to dsmc. The backup was taken regularly and succeeded
using the command _without_ the trailing slash, untill the 'actioned'
dir was removed.  In the dsmerror.log are the following;

06/07/05   12:51:08 WARNING: InsertSlashHack missing dirDelimter,
continuing...
06/07/05   12:51:08 ANS1228E Sending of object
'/prod/bsmsb01/app/generis/var/out/import/actioned' failed
06/07/05   12:51:08 ANS1304W Active object not found


I cant see anything on IBM's site other than one InsertSlashHack problem
that doesn't appear to be related, and various ANS1304W problems that do
not appear to be related.

A query backup of the offending directory shows an Active file exists

Now I understand that if a filesystem is specified for incremental then
you shouldn't give the trailing '/', but exactly what difference does
this make to the backup process? Both backups appear to go ahead and
process exactly the same list of files.

Could whatever 'InsertSlashHack' is be mangling the pathname and
concatenating the 
 
/prod/bsmsb01/app/generis       filesystem mount point

with   

var/out/import/actioned                 filesystem path to a dir

and getting 

/prod/bsmsb01/app/generisvar/out/import/actioned
 
instead of 

/prod/bsmsb01/app/generis/var/out/import/actioned.

?
