Oops! Had a problem with that Servlet


I have a 3020 that was re initialized, I reinstalled Ontap 7.3.3P5 as it was moved to a different site to be recommisioned.

How ever now I get the following errror

HTTP/1.1 500 Internal server error content-type: text/html

Oops! Had a problem with that Servlet

500 Internal server error

at netapp.fv.servlets.FilerViewServlet.service(

at javax.servlet.http.HttpServlet.service(

at netapp.servlet.NetappRunner.execute(



I've installed Data ontap twice now and still no go

Any help would be apreciated



Re: Oops! Had a problem with that Servlet


Few things you can check are:

Check If the client entry is in /etc/hosts.equiv, if yes remove it and try once.

There was a BURT 363139 which was closed after following suggestions:

> As mentioned in the burt description, user is seeing some java servlet

> problem, such type of errors usually happens when -

>  > disks have been zeroed

>  > root volume is offline or unavailable

>  > image of build is corrupt.

>  > contents of the /etc directory (or essential Java files) lost

>  > missing files (,, and rt131.jar  from /etc/java)


> Reinstalltion of the software as solution suggested by you is correct and if

> everything goes fine FilerView should work.

That burt was closed after the above info was posted in the burt.

See if this is useful.



Oops! Had a problem with that Servlet


I have checked the hosts.equiv file and it's empty.

The disks were all zeroed as I did a full install using option 4a off the special boot menu on friday and then did the Ontap install after that.

The root volume is online.

Re: Oops! Had a problem with that Servlet


Just wanted to confirm the reinstall instructions.

I do a software list, and I see the package there.

Then a software upgrade <packagename>

It goes thru and installs.

Then i do a download and reboot.

It all comes back online. I can access cifs shares but then when i go to filer view on the left hand side i get the above error.


Re: Oops! Had a problem with that Servlet


I re zeroed all the disks and started again redownloaded ontap and still no go.

Any more ideas ?

Re: Oops! Had a problem with that Servlet

hi this might be a damn this to check, but after running 4a, you did add a upload the setup files to the system and go through the setup process from the beginning and then added all the licenses required, before a reboot?

Try upgrading to a newer version of DOT and install a newer version after the re-init. process

Re: Oops! Had a problem with that Servlet


Thanks for the suggestion, yep i've run thru the setup and applied licenses. Still no go.
