I ran the amtapetype from Amanda 2.5.0p2 last night, took about 6 hours to
complete the estimate:
Model: Quantum Superload 3 LTO-3 16 Tape Library.
define tapetype QS3LTO-3 {
comment "Quantum Super Loader 3 LTO-3 16 tape library"
length 448369 mbytes
filemark 6403 kbytes
speed 37739 kps
}
I ran amtapetype on /dev/st0 on a debian Testing distribution.
SCSI interface VHDI 68 Pin Ultra 160 connector running on a Adaptec 39160
2 channel SCSI 160 PCI-X interface. Server DELL PE 850 Dual Core P4 3.4
