Hi Gurus

Is there any document to explain what's the improvement or bugs fixed from 2.2 to 2.4? IHAC use 2.2 during POC and it worked well but when in production environment, we tried 2.4 but could not start the service. but tight project schedule, we moved back to 2.2 which works well but customer want to learn the difference.

Thanks and Best Regards!

Hi TC,

MCTB 2.4 has signifiicant performance improvements and some defect fixed over 2.2. There is also a known defect in version 2.2 that can cause CFOD to fail in certain cases, so upgrading to 2.4.0 as soon as possible is important. Make sure the windows service is set to start "Automatic (delayed)". This should fix the start up problem.

There is an article in this forum announcing 2.4 which has information on the improvements ( http://community.netapp.com/t5/Data-ONTAP-Discussions/MCTB-Version-2-4-0-released/m-p/51327 ) If you search under the MetroCluster label for MCTB, you should also see other articles with useful information.

Regards,

Brian

Thanks a lot!

How to check the version? I run mctb version but return deamon version. How to check the mctb version (2.2 or 2.4)?

You can see the version under the Operations Manager->Maintenance->Scripts menu item:
