See the "Disaster Recovery" section of the NetBackup Troubleshooting Guide for information about recovering NetBackup master servers, media servers, and client systems after a disk failure. The procedures include re-installing NetBackup and may include re-installing the operating system if it is required.
You must first ensure that your computer and robotic hardware and any necessary network equipment is operational before you re-install NetBackup. You can then use an appropriate procedure in the NetBackup Troubleshooting Guide.
After you re-install NetBackup, you may have to configure robots and drives (unless you re-install NetBackup on the original system, in which case the device configuration will be restored if you recover the NetBackup catalogs).
