Based on the UPGRADE ADVISOR I ran from 9.14.1p9 to 9.16.1px, it gives me the blocker as shown in the screenshot below. It is FAS8200, and there are two shelf models:
DS4246 IOM6
DS224-12 IOM12
I browsed around Netapp Hardware Universe, but, couldn't identify which one really cannot be supported on the new release. Could you please help me out?

Iom6 modules are no longer supported
Any old shelf is not supported
Ds2246
Ds4246
Ds4486

It's mentioned here: https://docs.netapp.com/us-en/ontap-systems/eoa-hardware.html#shelves

We have A700 with DS4246 IOM6. So, cannot upgrade to 9.16.1 as well. What options can we have or do we have to replace A700 and with what systems?

you might be able to get a fPVR to have the old shelves supported. Other than that there's no way except replacing the shelves with DS224C or DS460C with IOM12 modules
rigid horizon
With options of replacing them with DS224C or DS460C, there will be data migration and downtime, to move data off DS4246, correct?
young crag
there are 2 ways: one, you buy new empty shelves, shut the system down and move the disks physically from the old to the new shelves, then remove the old shelves from the rack and put in the new ones. That is probably the cheapest solution but it requires downtime. The second option is to buy new shelves with disks, nondisruptively move the volumes over, then remove the old aggregates and remove the shelves from the SAS stack. All that can be done nondisruptively (but you need to make sure to not exceed the maximum number of disks for the system during the process)
dire pivot
What disks do you have in the DS4246 shelves? They most likely already have an EOS date so maybe makes more sense to also replace the disks.

A wierd question... I know that installing IOM12 i a DS4246 works, so the loop will link up at 12G but the disks link up at 6G (because of the shelf backplane).. Is this then supported? 😉
edgy geyser
Not really. I think It’s the shelf. Internally it’s a sas2 component and that has been removed in ONTAP 9.16.
young crag
yeah the only way to get the old shelves supported is via the flag that the fPVR provides

I'd like your help to elaborate on the option of nondisruptively adding new supported shelf for A700 to replace DS2246. The following is the output
::*> storage shelf show -node node-05
Module Operational
Shelf Name Shelf ID Serial Number Model Type Status
7.10 10 SHFGD1626000562 DS2246 IOM6 Normal
8.20 20 SHFGD1625000700 DS2246 IOM6 Normal
9.30 30 SHFGD1630000912 DS2246 IOM6 Normal
10.40 40 SHFGD1710000159 DS224-12 IOM12 Normal
16.50 50 SHFGB2032000130 DS224-12 IOM12 Normal
My understanding, to nondisruptively add new shelf, we will have to chain new ones onto existing stacks without adding additional disk adapters onon the controller slots.
What should I check to make sure if we can utilize the existing stacks/slots?
edgy geyser
You can place up to 4 shelves of SSD per stack. Most of us dont recommend more than 2 per stack.
With that said, I see 5 stacks. This means you have at least one more pair of SAS ports you can use for a sixth stack
Where is your root aggrs?
If you add new disks, make sure they are partitioned. You should use the "migrate-root" command to get root off the older disks
rigid horizon
root_aggr is located across stack 7,8,9, and 16, not 10 though.
So, you think I have one more stack is empty and can be used? How do I indentify the pair? Can following command help?
::*> node run -node node-05 sysconfig -ac

Do something like
system node run -node node-05 sasadmin expander_map
You will see all sas ports in use with attached shelves and any unused ports
You have three sas cards. 3x4 =12 12 ports. 12/2= 6 capable stacks
rigid horizon
Great!
I think I find what I need upon the command that you provided. But, just to confirm with you. (Slot11, port 11b and slot2, port2c) is empty, and can be used for new shelf. Correct?
::*> node run -node node-05 sasadmin expander_map
