Challenge

Tape Backup jobs and other tape-related tasks in Veeam Backup & Replication may fail for up to 15-30 minutes after a new uninitialized LTO-9 tape is loaded into the Tape Drive.

Tasks will fail with an error similar to:

Failed to inventory tape in Drive 1. (Server: ..., Library: ..., Drive ID: ...) Error: The device is not ready
Unable to exchange medium in library. The tape device is not ready
This will only occur the first time a new uninitialized LTO-9 tape is inserted into a tape drive.
Log Example
ERR |The device is not ready.
>>  |Tape error: '21' (The device is not ready.) 
>>  |--tr:Error code: 0x00000015
>>  |--tr:TapeHandle failed to get tape media parameters.
>>  |--tr:Tape initialization FAILED.
>>  |An exception was thrown from thread [3296].

Cause

This issue occurs due to the lengthy initialization process for new LTO-9 tapes, which occurs when the tape is inserted into the tape drive for the first time. During this initialization process, optimization occurs, which may take up to 20-120 minutes. While this operation is happening, the tape drive is locked and unavailable until the initialization completes. The duration of unavailability is longer than expected by Veeam Backup & Replication, which causes jobs and tasks to timeout and report a failure.

Solution

As this initialization time with LTO-9 tapes is unavoidable, new uninitialized LTO-9 tapes must be manually moved into the tape drive using native library tools before they are used with Veeam Backup & Replication.

 

 

More information

A hotfix is being developed to prevent Tape Backup jobs and other tape-related tasks from failing due to the lengthy inaccessibility period during the initialization of an LTO-9 tape. Instead, the tape jobs and tasks will wait while an uninitialized LTO-9 tape is optimized when first loaded into the tape drive. It should be noted that while this will prevent a Tape Job from failing, it will cause the Tape Backup jobs that attempt to use an uninitialized LTO-9 tape to run for longer than expected.

In the next major release of Veeam Backup & Replication after version 11a, there are plans to implement a solution to automatically trigger initialization when new LTO-9 tapes are inserted into a library managed by Veeam Backup & Replication.
