So, when the MODE PAGE 0x1d "tgtd: tgt_mgmt(336) 184 0 2 5 1 0 4 targetOps
mode_page=0x1d:0:0x12:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0, 2491" is
sent AFTER the setup sequence of:

tgtadm --lld iscsi --op update --mode logicalunit --tid 1 --lun=4
--params "element_type=4,start_address=500,quantity=3,media_home=/root/btapes"
tgtadm --lld iscsi --op update --mode logicalunit --tid 1 --lun=4
--params "element_type=4,address=500,tid=1,lun=1"
tgtadm --lld iscsi --op update --mode logicalunit --tid 1 --lun=4
--params "element_type=4,address=500,tid=1,lun=2"
tgtadm --lld iscsi --op update --mode logicalunit --tid 1 --lun=4
--params "element_type=4,address=500,tid=1,lun=3"

All the values are 'reset' to 0..

I'll add a check for null values and throw a warning (Tomo, should I
call assert() ??) if it occurs.

Cheers
Mark
