Changing Datadomain image owner
Hello All,
I have a datadomain storage server that is showing down, as one of its media servers is no decomissoin in the right way.
The storage server that holds DDboost over LAN shows down always. I'm trying to solve since like a week.
Is there work arounds? can i create another sotrage server then move all the media sevrers and images to it?

NetBackp picks one media server from multiple media servers that are attached/connected/checked with storage server, to act as polling server for that storage server. This media server is resonsible for storage server states (UP/Down). However this selection is a dynamic process, it means any media server can act as polling server for storage server. If you are suspecting storage server issue is due to decommissioned media server then there is a simple process to fix it.
Stop services on master and all media servers attached to storage server in question.
Start services on master server and only on one media server which you think has good connectivity with sotrage server. This media server will become polling server for this storage server and diskpool, disk volume and storage server should all be in UP state. If they are not then you need to troubleshoot it.
Once storage server issue is fixed now to move data from one storage server to another storage server (physically different DD boxes) follow these steps.
Configure new storage server and duplicate all images residing on old storage server to new storage server.
Once all images are duplicated, expire backup image copy on old storage server.
Use nbdecommission command to remove unwanted/old/dead media servers
Please Note: It is VERY VERY important to properly decommission (nbdecommission) media servers in you environment as it causes lot of performance issues and failures on Master server. Never leave any unwanted media server in your environment as it has the potential to ruin your planned vacation :smileyhappy:
