upgrading 2 nodes in a 10 node cluster

Linuxed — Wed, 18 Feb 2026 16:12:21 GMT

Regarding netapp ontap cluster. I have 8 nodes on version 9.16.1p4 and 2 new nodes on 9.16.1p3 can I upgrade the 2 nodes without disrupting service to the other 8 nodes. currently the 2 nodes are not in prod. the other 8 are.

If the upgrade disrupts the other 8 nodes at all I have to create an outtage which I do not want to do.

Should not be an issue

just upgrade the whole cluster to the same release, like 9.16.1P11

there are significant fixes/patches/firmware updates in this release

That's exactly what I don't want to do. I just want those two nodes up to P4.

you can use the cli:

cluster image update -node node-0x,node-0y -version 9.16.1P4

You really should upgrade. there are many known issues in those earlir version of 9.16

Oh trust me I see the "features" I just spent 3 days joining a brand new c60 to our existing cluster. It's just we are in the middle of a major hardware refresh cycle on this cluster and it's just not worth it right now.

Thanks for the solution!

LOL. I have my tools & toys

I almost never "just add" nodes to a cluster nor just use out of the box.

I do a full re-init of the system

-> Update flash from loader, set-defaults, netboot version I want -> puts image on both boot partitions, and redo the ADP.

Many times the customer orders "extra" drives and if i re-init, i can make the root partition at least a little smaller getting a little more extra capacity

This is the basic complete command:
cluster image update -node n0001, n0002 -version 9.16.1P4

Once we are done swapping out shelves then we're going up to 9.17.XX We'll cross that bridge when we get there.
