    vdbench to tape - Unable to find lun size for /dev/st0

    5e355534-3a66-445d-acb6-1b65f89ce9e6

      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

      ****

       

      Getting file open error.  Any idea what to change to fix this?
