Author: allanjude Date: Thu Jan 14 01:42:09 2016 New Revision: 293865 URL: https://svnweb.freebsd.org/changeset/base/293865 Log: MFC: r287473 Add the new sesutil(8) utility for managing SCSI Enclosure Services (SES) device. MFC: r287493 Fix iteration bug MFC: r287485, r287494, r287992 Please the angry gcc 4.2 gods MFC: r287988 Improve and expand sesutil(8) Return an error if no matching device is found Locate can address a slot, in addition to a drive Added fault, similar to locate but blinks a different LED Added the map command, lists all devices connected to the SES controller Added the status command, overall status of the SES controller MFC: r292092 sesutil: fix map not printing the status of the LED device in an array MFC: r292093 sesutil: pass the correct element type when printing the SES map MFC: r292121 sesutil: Add extra information specific to some SES devices to sesutil map MFC: r292122 Fix sesutil locate when a sesid is passed to locate command MFC: r292262 Show the enclosure name and id in sesutil map Relnotes: yes Sponsored by: Gandi.net Sponsored by: ScaleEngine Inc.
