Challenge
When using Veeam Backup & Replication 11 or 11a before P20211211, Tape Backup jobs and other tape-related tasks 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 readyLog 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
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.
Starting with Veeam Backup & Replication 11a P20211211, tape jobs will now identify and display the media calibration process in the Action log and will no longer time out should this process takes longer than 15 minutes.
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.
