This second bit of the SCSI error message should be part of the first message, or the second line should repeat the device information as in "sd1(ahc0:3:0): retries:4". Also, there is at least one similar error message in the SCSI driver that is split across three lines: 19:44:33 cabal1: sd1(ahc0:3:0): RECOVERED ERROR info:0x4b8a77 asc:18,1 19:44:33 cabal1: sd1(ahc0:3:0): Recovered data with error correction & retries applied field replaceable unit: ea sks:80,1 19:44:33 cabal1: , retries:4 I actually think this second layout where the description is on the second line is easier to read, but even in this case the trailing ", retries:4" info needs to be put on the end of one of the other lines. The leading space on the second (and third) lines of the messages should be cleaned up while working in the neighborhood too. >How-To-Repeat: Get the SCSI driver to report some disk errors, or something it thinks are disk errors. >Fix: >Audit-Trail: >Unformatted:
