NetApp-Harvest: Server returned HTTP Error

[JF-Louvet]

Hi all,

I have recently install Harvest 1.2.2 but get the following error when trying to poll for most of our 7mode controllers :

[PROD][root@parg3pharv001 netapp-harvest]# ./netapp-worker -poller n02sanp0002a

....

I can't seem to find supporting information for this error? Any information would be great

Thanks

Hi @JF-Louvet

If TLS is not enabled you can get some vague empty errors like this.  Is TLS enabled?

netapp> options tls.enable on

Ran into this myself, but it's an older version of ONTAP with no tls.enable option (8.0.3P4). Will Harvest not be able to run against those controllers?

Because vulnerabilities were discovered in SSL v3 you can no longer guarantee communications using it are secure.  As a result the SDK was also adapted to require TLS and I added the instructions to enable TLS in Data ONTAP.  If you have controllers that don't support TLS and you can't or don't want to upgrade them to a release that does, as a workaround you could use an older version of the SDK (I suggest 5.3) that still non TLS connections.

Here are the steps:

1) Download http://mysupport.netapp.com/NOW/download/software/nmsdk/5.3/ from the support site and copy into /tmp.

2) Extract it:

cd /tmp

unzip netapp-manageability-sdk-5.3.zip netapp-manageability-sdk-5.3/lib/perl/NetApp/*

3) Stop the poller

/opt/netapp-harvest/netapp-manager -stop

4) Rename current lib

mv /opt/netapp-harvest/lib /opt/netapp-harvest/lib-old

5) Copy 5.3 lib in place

mv netapp-manageability-sdk-5.3/lib/perl/NetApp/* /opt/netapp-harvest/lib

6) Start poller

/opt/netapp-harvest/netapp-manager -start

Please post if this allows collection or not, and kudos if it is indeed a solution for you.

I am getting below error while adding my 7-mode nodes. I have enabled options tls.enable on. Please help me to get this resolved

Nodes are running with “NetApp Release 8.2.3P6 7-Mode” and nabox version:  “NAbox 2.4.1 (2017-12-04)”

Hello.

This is a very old post... so I have no idea if it will serve you who asked the question, but serve someone like me who found it years later with the same issue!

I found I needed three things enabled in the 7-mode system for it to work:
options httpd.admin.access
httpd.admin.access all (or at least the harvest system)

options httpd.admin.ssl.enable
httpd.admin.ssl.enable on

options tls.enable
tls.enable on

 So check those settings!
