Solaris 10 10/08 Release Notes

cfgadm Disconnect Fails When Running Concurrent cfgadm Commands (4220105)

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.
