iscsi setup

[leftcranium]

The issue:
I had iscsi working on my box in the 10.X days. But I can't seem to recreate it on a 12.X or 13.04 release. I'm currently able to connect to iscsi target from my windows system.

The setup:
Here is what I've done and the error I get.

I'm guessing it's something simple but don't know what else to try.
thanks

try this first:

iscsiadm -m discovery -t st -p <iscsi_host>

It should give you the iqn to connect to.

try this first:

iscsiadm -m discovery -t st -p <iscsi_host>

It should give you the iqn to connect to.

Here is the output. It seems the failure is only on login.

Try:

iscsiadm -m node -T <iqn> -l

is there a firewall in between? is iptables disabled on your machine?

[leftcranium]

no firewall, iptables is set to accept.
