I have been trying to reactivate a tgt array I was using a few months ago. I am currently using 3.12 but, tgtdadm
fails with a:

tgtadm: Can't find the driver

I ran the following commands to configure it:

taskset  0x00000100 tgtd  --control-port 0 --iscsi portal= --iser port=3260

echo "Creating iqn.target0"
tgtadm --lld iser --mode target --op new --tid=1 --targetname iqn.target0 -C 0
tgtadm --lld iser --mode logicalunit --op new --tid 1 --lun 1 -b /dev/rssda --bstype rdwr -C 0
tgtadm --lld iser --mode logicalunit --op update --tid 1 --lun 1 --params scsi_id="$RSSDA_ID" -C 0
tgtadm --op update --mode target --tid 1 --name=MaxQueueCmd --value=256
tgtadm --lld iser --mode target --op bind --tid 1 -I ALL
