Title:
  User reports excessive ALUA retry messages

Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Xenial:
  Fix Committed

Bug description:
   SRU Justification:

      Impact:
  User reports excessive ALUA messages on Ubuntu Trusty, kernel 
Ubuntu-lts-4.4.0-91.114_14.04.1
  Messages appear after a LUN disappears and there are hundreds of them 
flooding the log...

  [263095.795873] sd 3:0:0:129: alua: rtpg retry
  [263095.795874] sd 3:0:0:129: [alua] Sense Key : Illegal Request [current]
  [263095.795876] sd 3:0:0:129: [alua] Add. Sense: Logical unit not supported

  This causes an intense requeing of the ALUA work queue for 60 seconds
  and it floods the kernel log

  UBUNTU: scsi: fixe excessive ALUA (LP: #1720228)
