Error Message

The "errors" file may also contain specific Tape Alert information:

Unix/Linux: /usr/openv/netbackup/db/media/errors
Windows: install_path\veritas\netbackup\db\media\errors

TapeAlert is a standard for devices to report diagnostic messages to the controlling application. A "No TapeAlert Messages" response is a good thing. Here's the list of codes and definitions as it exists today.
(from the ANSI T10 Specifications):

tapealert_codes = {

# 0x3B to 0x40 are reserved
}

Cause

A "tape alert" message is a critical, warning, or informational alert that occurs due to a tape drive or robotic library hardware event. These "tape alert" messages are stored on the tape drive or robotic library. Applications like NetBackup query the tape device or robotic library for these "tape alert" messages and display the "tape alerts" to the user. "Tape alert" messages are reported in the NetBackup bptm log, which will show in job detailed status if the VERBOSE entry is added to the Volume Manager configuration file (vm.conf). The tape alert technology detects and logs hardware and media errors.

Solution

It is important to remember that while NetBackup displays these "tape alerts," the alerts occur due to a tape drive or robotic library hardware event. Check the Operating System logs on Unix/Linux, or the Device Manager and Event Viewer on Windows for any hardware related errors.

Please contact the Original Equipment Manufacturer (OEM) for support with any errors found.
