I don't believe so as I am able to discover SCSI devices on my Emulex
fabric-attached, Emulex direct-connect, and Qlogic fabric-attached hosts
before starting this test.

  FC hosts become unresponsive during array upgrade

Status in linux package in Ubuntu:

Bug description:
  While running automated array upgrade, my FC hosts become unresponsive
  and / or stop logging . Sometimes the host stop logging to
  /var/log/syslog, but I can still SSH into the host. Sometimes I try to
  SSH to the host in the middle of the test and it'll prompt me for a
  username that I then input, but it hangs there indefinitely and I have
  to power cycle the host. Other times my host becomes completely
  unresponsive and I can't SSH into the host and have to power cycle in
  order to gain access again. I thought the host might be crashing, but
  I'm not seeing any file get generated in /var/crash. I also thought my
  hosts might be going to sleep or hibernating, but I ran "sudo
  systemctl mask sleep.target suspend.target hibernate.target hybrid-
  sleep.target" and am not seeing any improvements.
