Hello!
I try to setup iSER on my test nodes, but got an error "connection
timed out" on --login.
Next - is a step-by-step what i do:
on target node:
tgtadm --lld iscsi -m target --op new --tid 1 --targetname 22-90
tgtadm --lld iscsi -m logicalunit --op new --tid 1 --lun 1 --backing-
store /mnt/storage/sas/22-167 --bstype aio
tgtadm --lld iscsi -m logicalunit --op update --tid 1 --lun 1 --params
"scsi_id=id-22-167,scsi_sn=mp-22-167,vendor_id=CLODO,product_id=22-167"
tgtadm --lld iscsi -m target --op bind --tid 1 -I 192.168.15.8
sb-st0:~ # tgtadm --lld iscsi -m target --op show

...
if i do on initiator node:
/sbin/iscsiadm -m node -T 22-90 -p 192.168.15.5 --op update -n
node.transport_name -v tcp
then --login is works fine:
/sbin/iscsiadm -m node -T 22-90 -p 192.168.15.5 --login
Logging in to [iface: default, target: 22-90, portal:
192.168.15.5,3260]
Login to [iface: default, target: 22-90, portal: 192.168.15.5,3260]:

What i doing wrong?
Thank you.
