This section lists important DR bugs.

Network Device Removal Fails When a Program Is Holding the Device Open (5054195)

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:

  1. Remove or rename the /rplboot directory.

  2. Shut down NFS services.

    # sh /etc/init.d/nfs.server stop
  3. Shut down Boot Server services.

    # sh /etc/init.d/boot.server stop
  4. Perform the DR detach operation.

  5. Restart NFS services.

    # sh /etc/init.d/nfs.server start
  6. Restart Boot Server services.

    # sh /etc/init.d/boot.server start
