Hello,
trying to configure iSCSI storage domain.
I have configured a CentOS 6.5 server as sw iSCSI target with chap
authentication.
port 3260 is open for tcp connections.
I have an oVirt host that is CentOS 6.5 and when trying to discover targets
I get in /var/log/messages

BTW: chap user and password input fields could be wider, so that the whole
words input can seen on the screen. there is plenty of space... Also
password field should not be in clear text as it is now
The approach to successfully connect the LUN seems to be:
1) make discovery but with chap unchecked
2) the target then shows up
see
https://drive.google.com/file/d/0BwoPbcrMv8mvb1pET3VNMWJuRUk/edit?usp=sha...
3) now check the box for chap authentication and select login all
you now get the luns
https://drive.google.com/file/d/0BwoPbcrMv8mveExRMzN1Z0RtR1k/edit?usp=sha...
4) then select the lun(s) desired and select OK
is this correct? In case I think it should be disabled the chap option
during discovery phase...
otherwise I have not configured correctly my iscsi target perhaps.

Piotr, this looks like JSON-RPC mishap.
Can you take a look please?
