Defining LTO device classes
To prevent problems when you mix different generations of LTO drives and media in a
single library, review the restrictions. Also, review the restrictions for LTO drive
encryption.
Mixing LTO drives and media in a library
When you mix different generations of LTO drives and media, you must consider the read/write capabilities of each generation. The preferred method is to configure a different device class for each generation of media.
Mount limits in LTO mixed-media environments
In a mixed-media library, in which multiple device classes point to the same library, compatible drives are shared between storage pools. Ensure that you set an appropriate value for the MOUNTLIMIT parameter in each of the device classes.
Enabling and disabling drive encryption for LTO Generation 4 or later tape drives
IBM Storage Protect supports the three types of drive encryption that are available with LTO Generation 4 or later drives: Application, System, and Library. These methods are defined through the hardware.
