Affected models: ST2000NM0045 (Constellation ES.3) ST4000NM0023 (Enterprise Capacity v5 or Exos 7E2) Please note that neither the disks nor the adapter are defective, they work fine. The disks have the latest available microcode installed, but the issue occurred with the factory microcode too.=20 Even with very small sequential or random I/O, the driver enters into a not workable state. linux-scsi thread for this issue: https://www.spinics.net/lists/linux-scsi/msg116653.html I have uploaded a dmesg excerpt with debug logging that shows what happens = when I run a random i/o test with 128k block reads with 32 threads for 1 minute. --=20 You may reply to this email to add a comment.
