After Master server rebuild master server not able to create MSDP storage server.

Hi sumit_k1111 

You shouldn't need to rebuild the media server. Hard to give firm guidance other than connect back to Veritas support for assistance. 

You don't indicate if you were able to perform a catalog recovery, or you had to rebuild the master from scratch. 

The issue I suspect is that the storage server already exists on the media server and you need to connect this (and the disk pool) back to the master. 

The process to reconnect the media server to the master may require several steps. 

1. Create the media server entry in EMM (although you say you have done this). The basic syntax is:

   nbemmcmd -addhost -machinename <media_srv> -machinetype media -operatingsystem <os type> -netbackupversion <version on media> -masterserver <master server name>

2. Next, re-create the storage server:

   nbdevconfig -creatests -storage_server <sts_name> -stype PureDisk -media_server <media_srv>

   Here the sts_name and media_srv are often the same, but it doesn't have to be.
3. Finally add the credentials for the storage server:

   tpconfig -add -storage_server <sts_name> -stype PureDisk -sts_user_id <sts_user> -media_server <media_srv> -password <password>

Once you have done that, you should be able to create the disk pools using the Java GUI - as long as you select the same storage location, this will not change anything already saved. 

You may need to manually bring the disk pools up (it should happen automatically):

nbdevconfig -changestate -stype PureDisk -dp <disk_pool> -dv PureDiskVolume -state UP

The final steps will be to re-create the storage units - which is easily done using the Java GUI.

Finally, if you have not performed a catalog recovery, then you will need to perform a 2 phase import of the backup data in the MSDP pool. 

The deduplication guide has some useful help regarding MSDP recovery  (the chapter on "Recovering MSDP" and another on "Replacing MSDP hosts") for a variety of scenarios - it also has information on obtaining the storage server user name and a method to update the credentials if these are lost.

did you have an MSDP pool before on your media server?
or this is a new media server (no pools was created before on it).

This error usually means that something is conflicting with your new configuration which could be a left-over from previous set up.
