Vmware ISCSI Disconnecting
Good Afternoon, I have a standalone vanilla ESX host 10.0.3.5 connecting directly via ISCSI to Netgear NVX storage 10.0.3.1. (Seperate network) I just can't make the ISCSI connection stable, it...
1. Update to the latest firmware (http://www.readynas.com/RAIDiator_x86_4_2_17_Notes). You will need at least one disk installed to do this. So if you haven't installed any disks yet, install one disk and turn the NAS on.
2. You will need to reboot when prompted to install the firmware update. Wait for the firmware update to complete then verify that it was successful.
3. If all disks are installed, in Frontview do a System > Update > Factory Default. Otherwise power down, install all disks and do a factory reset using the boot menu: http://www.readynas.com/kb/faq/boot/how_do_i_use_the_boot_menu#nvx_nvx_pioneer_edition
If the new NAS unit came with 4.2.12 or later (the old one came with 4.2.9 or was last factory reset on that firmware as you can see from initrd.log) then a factory reset (hot-swapping of the disks would take much longer and is certainly not recommended if you haven't loaded any data onto the unit yet) may not be necessary, but it's still nice to do a factory reset after updating to the latest firmware when doing a new setup, to get a nice clean setup on the latest firmware.
Edit: If the NVX is already on 4.2.12 or later then yes a factory reset is all that would be needed to get 4k sector alignment. You should update to the latest firmware if you haven't already first.
One more thing. This should be pretty obvious, but make sure you can mount the iSCSI targets fine on the new NAS before factory resetting the old one. There is a config file from the config backup, /etc/ietd.conf that contains the information that Frontview uses to mount the targets. So you'll need to put the iSCSI files in /c/.iscsi (.iscsi is a hidden folder) on the new NAS (you can move the files when logged in to CIFS as "admin" if Veeam can't backup to there) and ensure the /etc/ietd.conf is on the new NAS. You could do a System > Config backup on the old NAS, unzip it, delete the other files apart from /etc/ietd.conf, create a zip of the "etc" folder (important that it is done this way so files are restored correctly), then restore that zip file on the new NAS.
