Perhaps

  parse/recognize:
     [    60.795168] sd1(umass1:0:0:0):  Check Condition on CDB: 0x00 00 00 00 00 00
     [    60.795168]     SENSE KEY:  Not Ready
     [    60.795168]      ASC/ASCQ:  Logical Unit Is In Process Of Becoming Ready
  instead of logging it like an error.

  figure out if there is some sort of notification that it becomes ready

  if there is a ready notification, hook that into online status and
  start scan

  if we received a "becoming ready", and if there is no ready
  notification mechanism, schedule a read scan attempt in 10s, just once
  and see how that goes.
