Event Logs: Backup Exec Alert: Job Failed - The job failed with the following error: Physical Volume Library Drive not available

 

Cause

The above error is caused by failing hardware (tape, tape device or drive, adapter card, cable and/or terminator). Tape driver issue.
 

Solution

1. Confirm the latest tape device drivers are installed. Veritas no longer provides tape drivers with Backup Exec.
 
https://www.veritas.com/support/en_US/article.100016050#Ensure_Device_Drivers
 
Veritas kernel-mode drivers and tapeinst.exe are no longer installed if Backup Exec runs on Windows Server 2012 or later. https://www.veritas.com/support/en_US/article.100012356
 
 
 2. Check the tape and/or tape device for " end marker unreadable" and/or multiple soft/hard read/write errors.  If found, perform the steps  below: 
  • Run a long erase on the tape showing the errors OR run a cleaning job on the tape drive showing the errors
  • Re-run the backup job to tape

 

3. If it is HP tape library, disable the HP server management agents by following the below technical article that will fix the problem,

Should the "end marker unreadable" and/or multiple soft/hard read/write errors re-appear, please contact the hardware vendor/manufacturer for further assistance.
 
An explanation of "soft" and "hard" write errors visible on the Statistics tab within Backup Exec is found in the following documentation:

4. Ensure that the latest firmware is installed for the tape device, robotic library, and Host Bus Adapter (HBA: SCSI, SAS, fibre channel controller, etc.). Ensure that the latest device drivers are installed for the HBA. Contact the hardware manufacturer for the latest firmware for the tape drive or robotic library, and for the latest firmware and device drivers for HBA. https://www.veritas.com/support/en_US/article.100016050#Ensure_Latest_Firmware
