If you chose the Disruptive Flash Method, the RAID subsystem and JBOD expansion units automatically restart.
That action temporarily disrupts I/O operations and drops your CLU connection.
After the screen goes blank, wait about two minutes, then re-establish your Telnet connection to the CLU. If
you cannot re-establish a connection, wait 30 seconds and try again.
