I’m testing a storage system and trying to run vdbench to tape  RHEL 7 host going to tape.

Run Definition

****

compratio=2

sd=default,threads=1

#Add tape drives to the SD devinitions

sd=sd1,lun=/dev/st0,size=3t,openflags=o_direct

wd=swrite,sd=sd*,readpct=0,seekpct=eof,xfersize=256k

wd=sread,sd=sd*,readpct=100,seekpct=eof,xfersize=256K

rd=sniaw,wd=swrite,iorate=max,elapsed=3M,interval=60,endcmd="rewind"

rd=sniar,wd=sread,iorate=max,elapsed=3M,interval=60
