https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195033 Bug ID: 195033 Summary: [cam] [scsi] [patch] unclean SCSI attached HDD power-off on shut down Product: Base System Version: 10.0-STABLE Hardware: Any OS: Any Status: Needs Triage Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: sneakywumpus@gmail.com Created attachment 149433 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=149433&action=edit Patch to spin down scsi attached disks upon power down Shutting down my system with ATA hard drives connected to several mps(4) LSI host bus adapters causes the SMART Power-Off_Retract_Count attribute to increase indicating an unclean power down. Attached is a patch to spin down the discs upon shutdown based on the code in cam/ata/ata_da.c and r203420/r214279. I'm running with this patch for over a year now and it works as intended on my system (Supermicro X9SCM-F with 3 IBM M1015 HBA's flashed with LSI 9210-8i IT firmware and 20 WD SE SATA drives). The patch also fixes a few variable formatting issues in da(4). -- You are receiving this mail because: You are the assignee for the bug.
