Hi Maor,
It is/was probably something really weird with my
single-server/self-hosted engine. As a test I was able to install oVirt
Node 3.5 on another machine that I could borrow for a short period, and
I was able to get it connected via iSCSI to my FreeNAS VM, so I am
satisfied (for my own info) that iSCSI connectivity does work (I didn't
*really* doubt it since others are using it; I was just a bit frustrated
on my last post)
That being said, I think there is something odd/weird when trying to use
iSCSI on a single server/self-hosted engine setup, from which the iSCSI
connection is also being served from (even from a VM)
In the case of the FreeNAS test, I had the "initiator" set to "ALL",
meaning any and all IQNs would be allowed to connect. I didn;t do
anything different on the FreeNAS side of things, and the oVirt 3.5 Node
that I installed was able to connect without any issue whatsoever.
I will try the steps you suggest if/when I ever decide to try this
again, but probably for a setup such as what I am testing, I will
probably stick to the "local" NFS storage (not yet sure if I will go
with or without gluster; doing so sort of gives me more felxability in
the future)
Regards,
Alan

Hi Alan,
basically, it could be that your ACL in your iSCSI server might be configured without the
Initiator IQN of your Host.
do you have any access to your iSCSI server?
also, can u try to connect to the iSCSI server directly from your Host and see if it
works:
1) First discover the targets:
iscsiadm -m discovery -t st -p {scsi_server_ip},{port}
2) Try to log out from the target you were trying to login before:
Example:
iscsiadm -m node -u -T {iqn.2015-07.com.target_name.redhat}:{port} -p
{scsi_server_ip},{port} -u
3) list your files at /sys/block
4) logging in to the target:
iscsiadm -m node -T {iqn.2015-07.com.target_name.redhat}:{port} -p
{scsi_server_ip},{port} -l
5) list again all your files at /sys/block, and check if there were new added block
devices.
Regards,
Maor
