(Probably silly) question about inserting blank tapes into library and being assigned wrong hcart type

Hi guys,

I'm totally new in the backup to tape world.

I am following a SOP that my predecessor left for the backup system. I loaded new tapes into the library, and my backups are not starting (error 96) because no media is available. After loading the new tapes I run an inventory and then assigned the correct volume pool.

But I can see that the previous backup jobs used hcart tapes, and the ones I loaded are labeled as hcart2 when I go to the robots section and check the list of tapes in the robot.

Could you help? What am I doing wrong?

Thanks!
