iSCSI not reconnecting - OS 6.6.1
I'm having a similar issue to both of these users who seemed to never get a resolution:
https://community.netgear.com/t5/ReadyNAS-in-Business/iSCSi-won-t-reconnect/td-p/971430
https://community.netgear.com/t5/ReadyNAS-in-Business/iSCSI-not-reconnecting/td-p/1112230
I have two ESXi 6.5 hosts that are connecting to a LUN on my ReadyNAS, and if they lose connection for any reason (switch reset, etc.), they will fail to reconnect to the LUNs. If I go into the iSCSI settings on the ReadyNAS, and set the allow initiators on my LUN group to 'any' and then back to 'selected', they will be able to reconnect again and work perfectly until they next interruption.
I want to secure the LUNs obviously, but if I can't rely on them reconnecting due to this issue I might have to leave the initiators set to Any. Has anyone else ran into this issue or know of a way to solve it?
A side question: is there any way to disable iSCSI on specific network interfaces? If I could disable it on my management network that would be a good work-around to keeping the LUNs secure.

Hi gpearson9,
Can you kindly send your logs. I will try to have it checked.
How do I send all logs to ReadyNAS Community moderators?
Regards,
Just sent the logs, thanks!
This has been fixed in 6.7.0, which is available as a public beta release.
On 6.6.1, network reconnections are not noticed if you are using static IPs. So if you prefer a temporary workaround instead of updating to 6.7.0 beta, you can switch your ReadyNAS to use DHCP instead of static IPs.
Good to hear, I will wait for the final release I think. Any estimate on when it might be available?
Just to be clear for your work-around, DHCP needs to be set on the network interfaces of the Netgear NAS, not the initiating clients?
There's no exact date yet, but I expect 6.7.0 to be available within the next month.
The ReadyNAS must be using DHCP to work around this. The initiators' network configuration doesn't matter in this case.
Well I found out the hard way tonight that this issue was absolutely not fixed in 6.7.0 (or 6.7.4 for that matter).
We had to restart our core switch over a configuration change, and as soon as we did all of our iSCSI devices started failing to log into the LUNs on the NAS... The same 'fix' as before worked, I went into the group for the LUNs and switched the Initiators option from 'Selected' to 'All', then back to 'Selected' and bam, all of the iSCSI devices re-connected immediately.
These devices simply cannot be used for iSCSI in this state... is there an actual fix planned soon??
Please send in a fresh set of logs (see the Sending Logs link in my sig).
