PROBLEM:  (None)    (Patch ID: TCR160-003)
********
This patch fixes a problem where DRD permissions could be lost if a service
is modified more than once.  In V1.6 new functionality was added to allow
the setting of the mode, owner and group of DRD devices by invoking the
asemgr utility to modify the DRD service.  If, after DRD permissions have
been set, the service is modified again these DRD permissions could be lost.
This problem has been solved in this patch.
PROBLEM: (80450) (PATCH ID: TCR160-063)
********
This patch fixes a problem that prevented the removal of LSM volumes from
a DRD service.  The problem occurs when there are multiple LSM diskgroups
in the service, and all of the volumes from one diskgroup were removed. 
The asemgr prints the following error message:
	*** `PD_svcname:/dev/rzb16g` is duplicate node.

and the removal of the volumes fails.  In this case, the physical disk was 
part of the diskgroup that was being deleted.
