Hi everybody

we have tsm 5.3.3.4 on solaris 8 with a diskpool on veritas filesystem. 
Backup works not well, starts with 5000 kb / sec and will be slower at 
every new try (slowest was 0,4mb/sec).
Restores work fine every time. Backup starts at 5000 KB/sec again when we 
unmount and mount the filesystem.
We tried a raw device für the diskpool and then we had always ca. 13000 
kb/sec for the backup.

Is it possible to tune the veritas filesystem that it will work better ( 
convosync=direct ( works not really better) ) ? Or any other tipp ?

Thanks for any hint, Karin
