Cause

VxUpdate is trying to upgrade the NetBackup client software and it is being informed on the client side that this might have NetBackup Server binaries installed.

Upon checking the NetBackup Administration Console, under Host Properties > Clients, the problem client (nbclient) was showing as a media server role, instead of a client role.

• The NetBackup version was checked; it was version 7.7 or higher.
• The operating system was checked; it was a supported platform.
• The software binaries were checked; it was a supported product.
  • The NetBackup Server binaries were not installed; no admincmd directory was present.
• The NetBackup configuration (bp.conf file) was checked...
  • Problem: The client had itself listed as an authorized server in the Server list.
  • Example:
    $ grep nbclient /usr/openv/netbackup/bp.conf
SERVER = nbclient.local  <<== This entry should be removed.
CLIENT_NAME = nbclient

Solution

Ensure the NetBackup client being upgraded, is only configured as a client, and there are no superfluous entries in the NetBackup configuration.

Steps to resolve the issue:

1. On the NetBackup Client, remove the SERVER or MEDIA_SERVER entries, which contain same name or aliases of the CLIENT_NAME.
2. After the entry is removed from the NetBackup, restart the NetBackup Client services.
   • Note: At this point, after refreshing the NetBackup Administration Console, the client machine role updated from media server role to client role, under Host Properties > Clients.
3. Then, retry the VxUpdate policy to upgrade the client, which should complete successfully and the updated client version should be reflected in the Administration Console after another refresh.
