DELL ML3 Tape Cartridges LTO 6

Hi Colleagues,

Good day! Currently we have DELL ML3 Tape Library with HH6 Tape Drives. We are inquiring with the Tape Cartridges vendor, and they don't have available Dell Ultrium LTO 6. May I ask if other or any Brand of LTO 6 Tape Cartridges can be use in our current Tape Library/Drive?

Thank you in Advance!
