RN316 - FW 6.6.1 - iSCSI CHAP Broken / Confusion
Hi All,
Ever since updating to 6.6.1, we've noticed that all our iSCSI drives, which use CHAP Authentication, keep dropping off / disconnecting.
On further investigation it seems that everytime we fix one on the ReadyNAS and go fix another, the previous one has changed, in the sense that the initiator configured on the previous drive, is now the new one configured on this drive. Yes, it sounds confusing, so here's a breakdown.
1) Configure an iSCSI CHAP Login for a specific initiator on iSCSI Drive A
2) Apply that change
3) Confirm that the connection works on the server requiring the iSCSI Drive
4) Configure an iSCSI CHAP Login for a specific initiator on iSCSI Drive B
5) Apply that change
6) Confirm that the connection works on the server requiring the iSCSI Drive B
7) Re-visit the configuration for iSCSI Drive A on the NAS
8) The initiator configured for Drive A now no longer exists, but the initiator for Drive B now exists on Drive A, albeit disabled.
9) Checking the configuration on Drive B exists as normal.
10) Repeat this process to fix Drive A, now Drive B is screwed and has Drive A's config.
HELP!!! This is doing my head in!!!
Can someone please advise a resolution to this or issue an urgent patch to fix?
Cheers,
Ray

- The iSCSI configuration on ReadyNAS OS6 has always confused me.
Like, by default, "Selected" is selected instead of "Any", resulting in the LUN to be unreachable with default setting (shares are reachable with default setting). Then if you add an initiator, its "allowed" option is unchecked, making it unsuitable by default too.
Then you get two separate CHAP options, one at the top, one at the bottom. They're not the same, but the first one doesn't clearly say it's not the same as the bottom one.
You really need to know what you're doing.
It's the complete opposite of user friendly, imo. Practice help...Thought I'd keep you all updated...
6.7 apparently doesnt work with the 10Gb NICs. They are "grayed out" in the interface, and missing from ifconfig when I SSH to the box.
I swear Netgear's QA is a joke.
I think I might just install Windows Server 2016 on the RN4220 and call it a day. I'm tired of wasting my time on this.
aalexandrebeta you shouldn't assume that 6.7.0 is a "magic" fix for any and every issue.
rmftechnologies based on your purchase date you should have lifetime online chat. You may wish to open a support case using that method.
nxtgen it looks like you may be a Powershift reseller. Have you considered opening a support case?
6.7.0 does have some updates relevant to iSCSI, however I don't think any of the changes I've seen have anything to do with CHAP.
I'd suggest waiting for the next build after Beta 3 before considering installing it on your RN316. Do note the support implications of trying a beta.
Does anyone have the older firmware and know how to downgrade?
I cant use this in a production environment this way.
The minute an unauthorized iSCSI Initiator hits the box, the iSCSI service on the ReadyNAS "hangs" and takes down all of my iSCSI LUNs and I have to hard reboot the box by shutting off the power.. if you try a restart from the admin interface, the box never comes back online.
This is junk as it is.
6.7.0 FW has been released.
FYI All...
A temporary workaround to keep the iSCSI drives connected is to allow "Any" initiator to connect to the drive.
Extremely poor QA'ing by Netgear here, but out of desparation, this will allow operations to continue until a patch is released.
Cheers,

The 6.7.0 FW is expected to be released and solve those issues!
Unfortunatly we have to deal with it!
Is this why I've been fighting iSCSI issues connecting to a single target/LUN from two separate initiators for the last 4 hours??? because, unless something has changed... CHAP and authentication are required to connect from multiple hosts...
First host works; the second gives me an authentication error and/or "service unavailable"
