Downgrade or revert new AFF A300 from 9.6 to 9.5

kelwin — Wed, 04 Jun 2025 12:07:59 GMT

We have 2 new AFF A300 system that came preinstalled with OnTap 9.6p2. Our exisiting clusters of FAS8040 are running 9.5p5. We'd like to downgrade A300s to Ontap 9.5. What are proper procedures for downgrading nodes? Our A300s are connnected to cluster switches (not part of cluster) but should we connect A300 nodes together when downgrading OnTap? Our goal is to downgrade A300s to OnTap 9.5 then initalize with ADPv2.

If these are new systems, it is faster to simply install another version. Use special boot menu 9a to remove existing partitions, then 7 to install desired version (needs HTTP server to download ONTAP from) and then 4 or 9b to initialize. After that join nodes to existing cluster.

You could do this:

1. Boot to Special Boot Menu

2. Option #7

3. Choose your interface (like e0M): TMAC's Hack: DO NOT say yes to reboot. Choose N

4. Option #7 (NEED a web server)

5. e0M is now selected (without a reboot)

6. Enter info (IP of interface, netmask, gateway if needed)

7. Enter URL of ONTAP package (same package you use to upgrade ONTAP)

8. Let it install and do its' thing.

9. During reboot, be sure to catch the Special Boot Menu

10. Choose Option 9

11. Get BOTH controllers to this point

12. Choose Option 9a on Node 1. Let it finish

13. Choose Option 9a on Node 2. Let it finish

14. Choose Option 9a on Node 1. Let it finish (you should see all drives listed)

15. Choose Option 9a on Node 2. Let it finish (you should see all drives listed)

16. Choose Option 9b on Node 1. Let it reboot, partition and start up ONTAP cluster setup.

17. Choose Option 9b on Node 2. It will reboot, partition and get to the ONTAP cluster Setup.

Although you can downgrade your new 300 to 9.5, my recommendation would be to upgrade your 8040 to 9.6 which is already up to P4. There are over 10,000 filers in the field running 9.6 and it's a stable and supported release (even-numbered releases used to be supported for only 1 year but that changed so it's now the same as odd-numbered releases).

kelwin — Wed, 27 Nov 2019 02:41:38 GMT

We've downgraded successfully but now we cannot join the cluster because of 2 different OnTap images. Current cluster is image2 9.4P4 image1 9.5P5, new A300 nodes are image2 9.6p2 image1 9.5P5. Are we able to set both images the same across all nodes in the cluster wihout causing issues.

aborzenkov — Wed, 27 Nov 2019 03:12:23 GMT

I doubt very much the problem is in different images. What version is currently active on AFF? Please, show actual console protocol of join attempt including error you get.

Re: Downgrade or revert new AFF A300 from 9.6 to 9.5

kelwin — Wed, 27 Nov 2019 11:33:56 GMT

Enter the IP address of an interface on the private cluster network from the

cluster you want to join: xxx.xxx.xxx.xxx

Joining cluster at address xxx.xxx.xxx.xxx

System checks .Error: Cluster join operation cannot be performed at this time: All nodes in cluster must be at the same ONTAP version before node can be joined.

Resolve the issue, then try the command again.

TMACMD — Wed, 27 Nov 2019 17:05:20 GMT

On the cluster, what does this show:

"system image show"

How about showing the full output of the serial session up to the failure on the A300?

Maybe there is something that was missed?

How did you "downgrade" to 9.5 on the A300s?

If you did not wipe(like I indicated earlier), that may be causing issues.

Re: Downgrade or revert new AFF A300 from 9.6 to 9.5

Thats a great start.

what about the rest?

Run the cluster setup from the CLI and show that output also.

I am wondering if the cluster is not communicating properly.

From the cluster (these are all auto-assigned 169 addresses, no real need to mask)

net port show -ipspace Cluster

net int show -vserver Cluster

net device-discovery show -ipspace Cluster

From the A300s CLI:

net port show -port e0a|e0b

net device-discovery show -port e0a|e0b

net i

FYI to those interested, we contacted support and after some digging they fouind a stale smf table entry blocking new nodes trying to joing the cluster.

Although Nodes 3 and 4 had the same version of ONTAP as the existing cluster they would not join because there was a stale entry in the smf tables.

4 entries were displayed.

There should be an entry for each node in the Cluster plus 1 entry for the Cluster.

We removed the 8.3P1 entry:

::*> debug smdb table cluster_version_replicated delete -uuid 3101b6df-7cec-11e5-8e37-00a0985f3fc6

Note: Do not edit the smf tables without guidance from NetApp Support.
