Re: After downgrading 8.1.2 to 7.3.7P1, can't login into my controller via OnCommand SM.

LKHAIMOVICH · ‎2013-03-05

After downgrading 8.1.2 to 7.3.7P1, I can't fully login into my controller via OnCommand System Manager: system info on the right is showing, but the left panel remains empty. Ath e time of login attempt the following message is printed to syslog:

[api.input.invalidSchema:warning]: Error in API input schema validation. API name: disk-list-info. Detailed error: Extra input: ownership-type.

Can this be the cause of login failure? Any ideas for fixing it?

Did you delete all of the snapshots? (part of the procedure to revert from 8.x back to 7.3.x).

Humm,

Can you try to delete your controller from Oncommand system Manager and re-eiscover it, for the moment I think Oncommand System Manager want an DOT 8 version

1. Check the compatibility of System Manager release and Ontap Version

2. Recreate the SSL/SSH certificates on the controller (secureadmin setup ...)

Maybe this helps,

Peter

Hi Leon

Try to clear all IE cached data&colon;

TOOLS --> INTERNET OPTIONS --> BROWSING HISTORY --> DELETE

Perhaps this helps

Thank you to everybody for your suggestions.

Deleting the browser's cache didn't work (I am using Firefox18).

ONTAP and OnCommand SM versions are compatible.

All snapshots were deleted AFAIK (There are clear error messages telling one which snapshots have to be deleted for downgrading to proceed).

I removed the system from OnCommand SM and... can't re-discover it anymore.

I guess, ssl/ssh certificates are relevant for the login but not for the discovery.

Sure I've exited and logged in into OnCommand SM.

What else could one try?

There is on interesting moment. Namely, the controller itself ("snap list" command) reports that there are only post-downgrading (later than March 3) snapshots, yet the admin host finding pre-downgrading directories and files.

On the controller:

gen-netapp2> snap list vol_10gb

Volume vol_10gb

working...

OK. It looks like there are conflicting accounts of 7.3.7P1 compatibility with OnCommand SM 2.0.2. In the latter's release notes it says:

Your storage systems must be running any of the following versions of Data ONTAP:

Data ONTAP 7G (starting from 7.2.3)

Yet the Interoperability Matrix Tool shows for OnCommand SM 2.0.2:

....

NetApp Data ONTAP 7.3.5.1

NetApp Data ONTAP 7.3.6

NetApp Data ONTAP 8.0 7-Mode

...
