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.
Workaround: As superuser, perform the following steps:
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 | 
If a cfgadm process is running on one board, an attempt to simultaneously disconnect a second board fails. The following error message is displayed:
| cfgadm: Hardware specific failure: disconnect failed: nexus error during detach:address | 
Workaround: Run only one cfgadm operation at a time. Allow a cfgadm operation that is running on one board to finish before you start a cfgadm disconnect operation on a second board.
