If a cfgadm process is running on one board, an attempt to simultaneously disconnect a second board fails.
A cfgadm disconnect operation fails if another cfgadm process is already running on a different board. The message is:
cfgadm: Hardware specific failure: disconnect failed: nexus error during detach: address
Workaround: Do only one cfgadm operation at a time. If a cfgadm operation is running on one board, wait for it to finish before you start a cfgadm disconnect operation on a second board.
