DB2 8.1.0 (to 8.1.7) AIX 5.2.0.0

Hi everyone

I'm trying to fixpack from 0 to 7 on my test machine
but I cant seem to kill the DB2 fault monitor daemon:

$ db2 "attach to db2inst1
> "

Instance Attachment Information

Instance server = DB2/6000 8.1.0
Authorization ID = DASUSR1
Local instance alias = DB2INST1

$
$
$ db2fm -i db2inst1 -D
fmSwitchToInstance2(): no proper authority to instance 'db2inst1'.
Failed to switch to instance 'db2inst1'
$


Does anybody know why?

Tank

PS: I have granted dasusr1 explicit sysadm privileges
