We currently use a Physical Tape Library (PTL) for secondary copies with long-term retention with a single generation of tape drives: LTO-7.
Our plan is to upgrade the PTL and install LTO-9 or LTO-10 drives alongside the current LTO-7 ones. The main reason is the amount of tapes in long-term retention that would be very costly to copy over to LTO-9/10.
Since neither LTO-9, nor LTO-10 is compatible with LTO-7, we would need to keep some LTO-7 drives to read from LTO-7 media alongside the new drives.
Is Commvault capable to recognize the LTO generation and use the compatible drives and if not, would it be possible to configure this manually so that the correct drive is used for the tape operations?
We run v11.32.
Thank you,

Hi @Zoltan ,
Commvault is capable of recognizing different LTO generations and using the compatible drives for tape operations. When you have mixed LTO drive types, such as LTO-7 alongside LTO-9 or LTO-10, each LTO type should be configured as its own drive pool. You need to ensure that the correct drive pool is included in the data path for the storage policy. This configuration will allow Commvault to use the appropriate drive for the corresponding media type.
If you encounter any issues with drive recognition or usage, you may need to verify that the drive pools are correctly associated with the storage policies and data paths. This setup ensures that the system can utilize both LTO-7 and the newer LTO-9 or LTO-10 drives effectively.
