Upgraded cluster, cannot merge node pools
We upgraded our (4x iq_32000x-ssd) with 3 more X400 nodes, with exactly the same configuration (disk, memory). After I added the new nodes I realized that they went to a new node pool, which is not what we wanted. Now we have a pool with 4 nodes and another with 3 nodes, and each one is protected with 2:1 , doubling the cluster overhead (correct me if my overhead logic is wrong).
I opened a case and they are telling me that merging these node pools is impossible since the nodes have different config IDs:
nyst0087-1# isi_for_array isi_hw_status|grep -i config | sort
nyst0087-1: Config: 851-0105-02
nyst0087-2: Config: 851-0105-02
nyst0087-3: Config: 851-0105-02
nyst0087-4: Config: 851-0105-02
nyst0087-5: Config: 851-0074-01
nyst0087-6: Config: 400-0029-01
nyst0087-7: Config: 400-0029-01
nyst0087-8: Config: 400-0029-01
Is this true ?
(We do not have SmartPools licenese, and with this configuration we do not need it)

This was caused by bug in 7.1.0 that is supposedly fixed in incoming 7.1.0.2
Engineering deleted the second pool an re-added the nodes to the first pool using internal use disi command

By upgrade I meant we added 3 Nodes to the existing cluster, not OneFS upgrade. We're running 7.1.

Hi Burhan,
There is only one X400 CTO node that is in the same equivalence class as the 32000X-SSD - and that node, specifically, is the X400-SSD 32TB/24GB RAM. It's equivalence class 5.
Here's a handy document. Since node equivalence changed from pre-7.x to 7.x, it's worth a read.

Thanks Rob
We have the following type of nodes
Isilon X400-4U-Dual-24GB-2x1GE-2x10GE SFP+-32TB-400GB SSD
Isilon IQ 32000x-ssd
According to the documents they are equivalent in class 5.

Node equivalence checks are not functional in OneFS 7.1.0.0. Please open a case with support so we can resolve this issue manually.
This will be fixed in a future OneFS update (likely the maintenance release after 7.1.0.1). When you open up the case, please reference internal bug ID 120151.
Thanks,
Bernie
