scsiadd adds and removes devices, scans for new devices, or prints the status of the SCSI bus. The options are:
add device
remove device
scan for new devices
print SCSI status
set maximum SCSI ID which is scanned


scsiadd need the /proc/scsi/scsi file to send its commands to the linux kernel. In 2.6 kernels this file is considered deprecated and you have to enable the following kernel option so this file is generated:
Device Drivers->SCSI device support->legacy /proc/scsi/ support

scsiadd -r 1

scsiadd -s
