Hi Marty_M and thanks...
There is no change after firmware update. Disks are too busy syncing to process even moderate loads via iSCSI causing iSCSI timeouts where the disk drops.
Thanks,

Hello edecanus,
Are you working with one iscsi lun? Have you tried creating separate iscsi luns for snapshot, backup and data access? There is a possibility that the NAS is having trouble with work load coming to different process going to single lun.

Hi Marty_M,
I did reconfigure iSCSI by moving data for long term storage to a single large LUN. Addiitonal iSCSI were created to segregate the work loads across multiple smaller LUN. This is working well as the ReadyNAS overall can now handle the workload better and I'm see as much as a 20% average increase in throughput.
I did reboot the server after all the configuration changes and data moves were completed when after 12+ hours this action did not complete. I was able to login to the ReadyNAS with limited options (i.e. iSCSI and other "settings" where non-responsive or froze the ReadyNAS session. I was able to launch "scrub". This took about 22 hours without the server connected and resulted in iSCSI and other settings responding as expected.
Thanks for the help!
