Re: How to upgrade DFM version 4.0 to latest Operation Manager version?

christy · ‎2016-07-17

We are currently running DFM ver 4.0D14 on windows 2003 server (32-bit) .

We want to migrate the this old DFM from windows 2003 to new windows host (windows 2008 64-bit) and the database able to restore to the new server.

However i am not able to upgrade the DFM version (4.0 to 5.0). It just hung during the installation page.

What is correct process to upgrade our old ver4.0 to newer version ? If you have any comments or suggestion , I appreciate. Thank you in advance.

Hi Christy,

I would suggest to install the new version of DFM on your new windows machine ( WIN 2008 ) and restore your OLD DFM DB to it, Procedure as follows...

Prerequisite:- Have a copy of your DFM license and keep it safe

dfm license list

Procedure:-

Stop/Start services as below

dfm service stop

dfm service start sql

dfm backup create -v

Note :- This creates a backup file (.ndb format) which is stored in the <install_dir>\Netapp\DataFabric Manager\DFM\data folder.

Disable any monitoring or purging

dfm option set discoverEnabled=No

Windows: for /f "tokens=1" %i in ('"dfm host list -a | findstr /I "yes""') do dfm host delete -f %i | echo HostID=%i

Perform another backup

dfm backup create -v

Note:- This creates a backup file (.ndb format) which is stored in the <install_dir>\Netapp\DataFabric Manager\DFM\data folder

Copy the .ndb file to a safe location to be use to restore on to the new server

Now login to the new windows machine ( Windows 2008 )

Install the new version of DFM

Restore the backup

dfm backup restore <path-to-dbfile>

Change the new server DNS names to olddfm.local ( In case if required )

Once done , Start all the DFM services

Note:- If you think you have huge number of mark-deleted objects , use purge tool to purge all the deleted objects

HI Nayab,

This is the first attempted we tried whereby the new server Win 2008 installed with latest DFM version. However the restore DB was failed and we tried several of attempts.

Now the new server is able to run with the old DB restore data. But we are stuck on how to upgrade it to newer version. Any idea?

Hi Christy,

Sorry, I have missed out that you have already tried to do it , Could you check the windows logs ( Application logs ) and look for the exact error ?

Thanks,

Nayab

There's no error on the application log(event viewer). The installation ran half way and it went into the hung state. The version i try to upgrade is 5.2.1P1.

From dfm.log it seems hung durng the cleaning the history tables.

Hi Christy,

May i know the version of

ONTAP ?

JAVA ?

As i see the upgrade is trying to delete the expired or stale data, Could you run PURGE tool and then try to perform the upgrade once again ?

After running Purge tool perform a reboot and then try to upgrade.

Thanks,

Nayab

IIRC there is no (supported) way to upgrade from 4.0 to 5.2 directly. Too many DFM and especially Sybase versions inbetween.

As 4.0 is 32bit only and 5.2 is 64bit only, there are also data conversion issues when trying to restore the 4.0 DB backup into a 5.2 instance, which may be the problems you see.

The one way that used to be supported was to upgrdae 4.0 to the latest available 32bit version, which was 5.1. Then convert 32bit to 64bit by importing the 32bit DB into the 64bit version of the same release and afterwards upgrade that version to the latest DFM / Operations Manager 5.2.

Unfortunately all versions prior to 5.2 are EOA and EOS for a very long time now, so you are on your own.

Nevertheless I still found a 5.1 releas on the support site:

http://mysupport.netapp.com/NOW/download/software/occore_win/5.1P1/

Good luck.
