Note: This section is Applicable to migrations which involves NetBackup versions 8.1 and later.

Headline

NetBackup uses security certificates to authenticate NetBackup hosts. The security certificates conform to the X.509 Public Key Infrastructure (PKI) standard. A master server acts as the Certificate Authority (CA) and issues digital certificates to hosts. NetBackup 8.1 and later hosts can communicate with each other only in a securemode. NetBackup 8.1 hosts and later must have a Certificate Authority (CA) certificate and a host ID-based certificate for successful communication.For more details please refer to the NetBackup Security and Encryption guide.

So for catalog migrations between NetBackup 8.1 and later , CA Certificate and host ID certificates need to be deployed to all the NBU hosts from the destination master server. Tranzman has a brilliant feature named Host Management which does these deployments.Additionaly it also helps you to check the NBU connectivity within hosts so before switching to destination master server in production any connectivity issue could be highlighted and fixed.

You can access the Host Management from Tranzman UI under Actions->Host Management.Certificates is a vast thing in itself so to understand it better you do need to have some basic information information on how certificates actually work in NetBackup.

Follow the below steps to deploy the certificates from the destination master server to the NBU hosts :-

Step 1

Click on Actions->Host Management.Now as we are already in the data transfer stage all the NBU hosts should be discovered and should be displayed on the Host Management Page under Client Mangement. e.g. Figure 1 shows all the NBU hosts including media servers.

Figure1

Step 2

Select all the eligible NBU hosts then Actions -> Run origin connectivity test as shown in the below screenshot(Figure2) and hit . You would see couple of jobs being triggered named CheckConn under Views->Activity Monitor. Wait for them to complete and the respective columns on the Host Management page should get populated with rather than .

Figure2

Step 3

A successful connectivity test from origin should move the media servers to the Media Server Management tab(as shown in Figure 3) and only backup clients should be seen under Client Management(Figure 4). As it can be seen most of the columns are populated in Figure 4 , please refer to the below table to check what the respective column means in host management. Any unexpected in any column should be fixed before proceeding to next steps.

Step 4

Now as shown in Figure 2 there are different actions which can be performed on NBU hosts. Below table shows all the Actions that can be performed on the NBU hosts.

Note: Do not select Update accelerator track-log destination, Remove origin from host properites,Make destination the master in host properties unless you are certain to use the NBU host with destination master server. Before running Push destination certificate ,reset the Netbackup security level for certificate deployment to Medium.

Follow the above steps for any Action to be performed in Host Management and fix any unexpected .

Note: Connecitivity test in Actions always take precedence before any other Action, be it from the origin or destination master server.
