OnCommand System Manager recieves error 500

[atinivelli]

Good day, i am running OnCommand System Manager ver 3.1.1 on Windows.

Today, for the very first time, i have seen this issue: i can connect to my 3210 running DataONTAP 8.0.3P2 7-mode, but when i try to reach my new 2240 running DataONTAP 8.1.3P3 7-mode i recieve an error 500 "connection refused".

I have found this workaround: on the 2240s i have issued the command >options httpd.admin.enable on ;

after this the OnCommand System Manager probably still tries a secure connection, on the console i see errors like 

[hostname: HTTPPool03:warning]: HTTP XML Authentication failed from MyClientIP . 

But now i guess OnCommand System Manager falls back to a non secure connection, i see the question "do you want to set up a secure connection or continue without...", i answer "continue without" and i'm able to manage my filers again.

What's happened? Maybe something java updates related? Thanks in advance.

For System Manager 3.1.2 to manage storage systems running Data ONTAP 7.3.x , 8.1.x and 8.2.x operating in 7-Mode ,TLS protocol must be enabled

If TLS protocol is not setup , System Manager 3.1.2 will display an error while adding to home page that TLS is not setup

TLS protocol is enabled by default for storage systems running Data ONTAP in Cluster mode.

Refer to https://kb.netapp.com/support/index?page=content&id=9010008

The next version of 3.1.2, targeted for end of March or early April, will officially support Java 8

We are using OCSM version 3.1.2 and still have this same issue with Java 8. Only way to access filer is to have httpd.admin enable on and then get non-secure connection warning.

Java on client side is a pita. I also wish they would drop it.

First version of the software needed Adobe Flash Player. Go figure!

I had 3 different versions of 32-bit java (72,75,76) installed and one 64-bit 7u76. Removed all versions. Downloaded 7u71 32-bit and 64-bit and installed. No more connection refused errors!

OCSM 3.1.1

Java 1.7 Update 75

Win7 SP1 32bit German

2 Netapp Systems - FAS2020A (Ontap 7.3.7P3) and FAS2220 (8.1.4P7 7-mode) in Snapmirror relation.

We found out that the FAS2220 system stopped to reject SSL connections after we rerun secureadmin setup ssl with 2048 key length.

The FAS2020a still rejects the SSL connection and offers to set it up, but it screws up the certificate with FQDN fqdn instead the "right one".

What worked for me, was to uninstall all existing versions of the x86 and x64 JRE, and install version 7u71. This is for OCSM 3.1.1 on Windows 2012 R2.

I d/ld the JREs from here ---

---and verified the MD5 signatures against this official Oracle webpage. One should always be cautious on the Interwebs, yes? you know

The following below fixed the issue.

Java 8 

OnCommand 3.2.1

To enable TLS in DataONTAP, login to the filer via SSH and issue the following command: options tls.enable on

Thanks Eddie

This was the fix I was looking for. Plain simple command to enter and all done.

Running version 3.1.2 of NetApp OnCommand and Java 8.51

All working GREAT!

[SLC_TAYLOR]

running

options tls.enable on 

fixed it for me. 

Environment:

7-mode

8.2.3P4

Java 8u51

IE 11

Thanks for the tip! 

[ATX_SW]

this worked for me:

options tls.enable on

Environment:

jre-8u60

OCSM 3.1.2

IE 11

Thanks!

As long as I don't let Java update higher than 8u51 it is working.   But any updates higher than 8u51 bring back the error 500.

Why oh why would any company build an enterprise application that depends on Java --- it's just a poor way to do things.  

[niels]

Hi Blaine,

we understood that as well, that's why we moved System Manager into the cluster rather than a thick client and it's solely based on HTML5.

Unfortunately it took a major release to get that done so only available for Clustered ONTAP 8.3+.

For 8.2.x and anything before that we have to live with Java and its flaws...

Hang in there!

Regards, Niels

Definitely the case. Had 7u75, got connection refused with OCSM. Uninstalled 7u75, installed 7u71 and it works just fine.

Why don't NetApp include (embed) the correct Java version in the System Manager install? This is common practice for apps that need a specific version of Java, instead of relying on the system installed version.

You must check these are on:

options httpd.enable

options httpd.admin.enable

options tls.enable

If they are off, set them on:

options httpd.enable on

options httpd.admin.enable on

options tls.enable on

And you must uninstall version 8 and install previous version7 of Java.  You can get from here:

https://java.com/en/download/manual_java7.jsp

That should fix it.

[20thCenturyBoy]

Uninstalling a newer version of Java is not a solution.

OnCommand System Manager 3.1.2 RC2 is now available. This release provides support for Internet Explorer 11 and support for 32-bit or 64-bit Oracle Java Runtime Environment (JRE) 8. Visit the NetApp Support Site for more information.

Thanks Joner

This fixed it for us on 8 filers.
Running
OCSM 8.1.2RC2
Java 32&64bit Version 8.45

[brgsstm]

This situation is absolutely ridiculous, new PC here with Java 8 U45 both 32 and 64 bit using 3.1.2 RC2 and still not able to get in.

Sort it out NetApp, installing old versions of Java is not a solution!

[yuvaraju]

Are you not able to install System Manager 3.1.2 RC2 or System Manager does not launch after installation.
