The original reporter didn't provide logs...logs would not help. Here's the original text of this issue as reported by NetApp test engineer.
Problem report from NetApp: We’re testing Ubuntu 18.04 before its upcoming release this month and have found that the most recent kernel that they have pulled in (4.15.0-15-generic) contains the lpfc driver 12.0.0.0. This driver version seems to have lost support for the LPe16002-M6 adapter but it DOES have support for the LPe16002B-M6 adapter. I’m assuming that you guys are major contributors to your own lpfc driver, so I’m hoping you can shed some light on this one before I have to resort to going out to the community. The previous lpfc version, 11.4.0.1, that was in an Ubuntu 18.04 beta, worked fine on the “non-B” card.
