Handling Process
1.  Check whether the license has expired.

   a.  Log in to the HDP3500E as user root.

   b.  Check the license status in the /usr/openv/netbackup/bin/admincmd/get_license_key file.

   c.  Run the f command.

   d. Type the host name hdp3500e and press Enter.

NOTE:
hdp3500e is the default host name. Type the correct host name based on the onsite environment.

   e.  The license status information is displayed, as shown in Figure 2.
  • If the license has expired, an expiration date is displayed in the status information. You need to add a valid license to recover the NetBackup service.
  • If the license has not expired, Expires: No Expiration Date is displayed in the status information.

2.  If the license has not expired, check whether the NetBackup is abnormal.
