backup with LTO3 and LTO6
In my robot, i have 4 LTO6 drives and 4 LTO3 drives. The drive type of LTO3 and LTO6 is HCART3 in my master/media server.
I have 2 storage units, one for LTO3 and the other for LTO6. the 2 storage units have "hcart3" density and the media type for LTO3/LTO6 is hcart3.
My question is : how Netbackup can tell to LTO6 drive to backup to LTO6 tapes and to LOT3 drive to backup or to restore from LTO3 tapes ? At the moment i have a problem, the LTO6 drives try to restore from LTO3 tapes, then my restore is ko.
Any ideas please ?
