What do you need to do this for?
How about just echoing the command to /proc/scsi/scsi
echo "scsi remove-single-device X X X X" >/proc/scsi/scsi
get the values for the various X's from /proc/scsi/scsi e.g.
Host: scsi0 Channel: 01 Id: 00 Lun: 00
Vendor: MegaRAID Model: LD 0 RAID1 69G Rev: 521S
Type: Direct-Access ANSI SCSI revision: 02
would be 0 1 0 0
