Is there any impact of upgrading OST plug-in on media server

[rVikas]

Hello Everyone

We have EMC datadomain used as storage target. Below are the details for that

                        Model                          DDOS Version             OST Plug-in version
            DD860/DD670/DD610            5.4.2.1-423209            2.4.1.0-289644    

I would like to implement NBU accelerator fetaure for few of the clients.

Accelerator requires OST plug-in at version 2.6 or later.

Does upgrading OST plugin on media server have any impact.

Can we upgrade OST plugin while backups are running or do we need to stop the backups?

Does it require to restart media server services after upgrade.

NBU services must be restarted after installing updated plugin.

I would personally suspend/stop all activity on the media server before updating the plugin.

HirVikas,

Does upgrading OST plugin on media server have any impact.

ans: you need to check the plugin OS compatibility as well

Can we upgrade OST plugin while backups are running or do we need to stop the backups?

Ans: No. you need to stop the Netbackup services first and then upgrade the plugin.  

Does it require to restart media server services after upgrade.

Ans: for installation of the plugin you need to stop the netbackup services.

Upgrade the DDOS to 5.4.5.0 as well. There is a lot of accelerated backup issues in DDOS plus you are running a version open for both poodle, ghost and shellshock vulnerability.

If you have a EMC support account, this page show what DDOS versions released

Thanks Nicolai.

Its very difficult to tell management regarding DD OS upgrde .. as the model which we are using is no more supported by EMC.

So i am not sure if DD OS upgrade cause any issue

OST plug-in is the major requirement for accelerator hence we are implementing it.

Data Domain OST plugin requires an OST license from EMC.  If your hardware and OS are not supported by EMC anymore, you likely won't be able to get a current OST plugin to work successfully.  And you would need an EMC account, and therefore a valid support contract, to get a copy of the plugin, correct?
