The presence of StorEdge A3000 daemons (rdaemon) prevent a DR Detach operation from completing if the operating environment must be quiesced (that is, suspended and resumed) to detach non-pageable memory.
Workaround: Temporarily disable the daemon before the DR operation, then restart the daemon after the DR operation by using the following command:
# sh /etc/rc2.d/S90amon stop
# sh /etc/rc2.d/S90amon start
