can anyone refer me to any documents re:Upgrading ESH Modules on DSMK14 for OnTap 8.x upgrade? I am looking to potentially buy used modules off of ebay, and dont know if they need to be configured for my system, or if i can just swap them out one at a time for a NDU, or if I need to shut down the system entirely (single FAS3140 controller)
* The DS14MK2 shelf is End of Hardware support in June 2013 anyway, even if you use ESH4 modules.
* If you don't care about NetApp official support you can still use ESH2 modules with ONTAP 8.1. It will still technically work and ONTAP does not even report the presence of ESH2 as an issue. We ran ESH2 with ONTAP 8.1.0 for a short period of time without any issues, see next point.
* If you care about support and you just need the ESH4 for a short period of time to decommission the DS14MK2 shelves, you might consider requesting a PVR with NetApp for running your system temporarily with ESH2 and ONTAP 8.1.
