Storage units need to be recreated after Master server changed?

[tigerlover]

I need to move my environment to a new clustered Master server. WWN  for the tape drives and robots will stay the same.  I have two questions:

1.Do I need to recreate storage units for the Media servers after that? If I change the bp.conf and restart the NBU processes, these will autmatically put my storage units controlled by new Master server snad Media server?

2. If the robot number changed -- previous TLD 0 became TLD1, previour TLD1 became TLD 0. Does this matter?

Best to delete existing devices and re-run device config. If robot numbers have changed, you will have to re-config STU's as well (and STU's in policies). 

Please remember to fail over to 2nd node and run Device Config wizard again.

.... If I change the bp.conf  .....

What do you want to change in bp.conf?

I know the new Master server need to have device reconfigured and failover to configure the other node. How about the Media servers? Do I need to delete devices and re-run device configure, rebuild the drives on all Media servers? This is a long process and I have more than 60 Media servers.

I changed the bp.conf on all Media servers by puting new Master server ( Virtual name)on the first line and also changed EMM server to new Master server ( Virtual name).

How exactly have you moved the environment to the new master ?

What method did you use to bring across all the old images for example, did you run a catalog recovery ?

I built new Clustered Master server then manually created Vpools/policies/storage units on Master server. I can not do catalog import since a single node Master server's catolog can not be imported into Culstered Master server with different name ( unless you use prefossional service ). When I need to restore, I will manually run two step image import procedures then do restore.

Since to media server, only the Master server's name changed, I am wondering if I need to rebuild the storage units. I am assuming the NUB process restarting can let it detect the new Master server and put the storage units under new Master server control. But I am not sure if I am right.Thanks!

Best is to run the Device Config wizard after the installation. This will add devices and storage unit(s).

No device config or STU config is stored on media server - only in the EMM database on the master server. This means you need to recreate devices and STU's.

[tigerlover]

Do I need to delete the existing devices before creating new ones? Do I need to rerun sg.conf?

[Marianne]

What existing devices?

A NEW clustered master server will have BLANK (empty) EMM database.

As per my previous post - device config is not stored on the media server(s) - it is stored in EMM database on the master server.

If you did not perform catalog recovery, you need to recreate devices and Storage Units.
