NetBackup Error 7640 Fix

Backups failing for only a specific host with the error 7640?  Here's how to fix that!

All of the following commands are to be performed on the client!
  1. Run this command:
    /usr/openv/netbackup/bin/bpclntcmd -pn -verbose -debug
  2. If the error ends with "the peer host certificate cannot be verified," continue.
  3. Stop the NetBackup service (reminder: on the client):
    /usr/openv/netbackup/bin/goodies/netbackup stop
  4. Start the NetBackup service:
    /usr/openv/netbackup/bin/goodies/netbackup start
  5. Recheck the status:
    /usr/openv/netbackup/bin/bpclntcmd -pn -verbose -debug
  6. The certificate error should no longer be seen.
  7. Retry the failed backup or wait for it to run again.
