When I use vdbench to run JEDEC 219 workload , I found that the "S.M.A.R.T attribute enable command (0xD8)" was issued in each write DMA data.
sd=sd1,lun=\\.\E,align=4k,threads=32 ,
wd=wd1,sd=sd1,rdpct=40,seek=100,xfersize=(512,4,1k,1,1.5k,1,2k,1,2.5k,1,3k,1,3.5k,1,4K,67,8k,10,16k,7,32k,3,6 4k,3),range=(1,5),skew=50
wd=wd2,sd=sd1,rdpct=40,seek=100,xfersize=(512,4,1k,1,1.5k,1,2k,1,2.5k,1,3k,1,3.5k,1,4K,67,8k,10,16k,7,32k,3,6 4k,3),range=(6,20),skew=30
wd=wd3,sd=sd1,rdpct=40,seek=100,xfersize=(512,4,1k,1,1.5k,1,2k,1,2.5k,1,3k,1,3.5k,1,4K,67,8k,10,16k,7,32k,3,6 4k,3),range=(21,100),skew=20
rd=SSD_Sustain,wd=wd*,iorate=3000,elapsed=1000h,interval=60
But in our special case , we need to test the drive without the "S.M.A.R.T attribute command "
Is there any way to disable this command ?
