Hello. I have NetApp 2240 ONTAP 8.1.4 7-mode and I want to upgrade it to last version. Looks like I should convert it to cluster mode and ther upgrade but I have no idea how to do it and where can I download software. Could someone send instruction and software please?
You cannot upgrade from 7-Mode to C-Mode. It is complete new installation and what was present on this system does not matter. You may consider updating BIOS/firmware to the latest version before installing C-Mode though, using 7-Mode. I have seen cases when ONTAP failed to boot on too old firmware.
I understand the urge to upgrade, but if the array is able to run at its current version, you could consider continuing to use it in production until replacement parts or third party maintenance costs get too high. I know of several EOL 7-mode systems still running ONTAP 7.x just fine, better than being melted down for scrap or used as paperweights!
Having several times stuck pieces of paper under NetApp controllers, I cannot recommend the FAS2240-2 as a paperweight - its lack of handles makes it very difficult to move. Likewise the FAS2240-4's handles are very thin and not ergonomic. The most ideal paperweight in my view is the FAS3200 series of controllers.
