Informix logging to tape problems using onbar and

Hey all..Can anyone help.. Informix ver - 7.1 OS ver - 5.5.1 Solstice Backup ver - 5.0.1 server Sun 4000 We use Solstice backup to manage the backup regime. We have 3 policies DBMIdata (informix database), DBMIlogs (logging) and default (unix file system). We are using a tape library to backup our informix database. 0cbn backs up the database while 1cbn backups up the logs. We also have a DLT drive that backus up the unix file systems. The problem we are encountering is that it all works fine except the logs are getting written to 1cbn but the uksun1_shm (shared memory logs ) are getting written to the DLT drive. In onmonitor the logging tape parameters are set to 1cbn, and the actual entries in onconfig and set to 1cbn..backup method is ontape -l Does any one know why we are getting logs written to the 1cbn (header shows alias of informix database (uksun1) and the DLT (header shows actual database name uksun1_shm) drive ? Also the DLT drive shows that after a backup the DLT tape is 78% full with 7.7Gig on the tape. I've looked at the volumes in nwadmin and they show the unix file system and the log entries but this is a new server and it does not contain 7.7 gig of data yet. All the 0cbn,1cbn and 2cbn entries in nwadmin are correct... Any pointers would be very much appreciated. Many thanks Robert
