If a process is holding open a network device, any DR operation that would involve that device fails. Daemons and processes that hold reference counts stop DR operations from completing.

Remove or rename the /rplboot directory.
Shut down NFS services.
# sh /etc/init.d/nfs.server stop
Shut down Boot Server services.
# sh /etc/init.d/boot.server stop
Perform the DR detach operation.
Restart NFS services.
# sh /etc/init.d/nfs.server start
Restart Boot Server services.
# sh /etc/init.d/boot.server start
