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).
