Disconnecting the Fibre Channel
If redundant connectivity is not used, then a Data Domain system does not support temporary Fibre
Channel disconnection while the Data Domain system is active.
Removing the fiber cable that connects the Data Domain system and the storage array may lead to a
system reboot at any time that the Data Domain system has I/O activity.
Note
Data Domain recommends shutting down the Data Domain system before removing the
cable.
