[SOLVED] Problem using tape drives as SCSI pass through - PROXMOX VE4.2

[jandro]

Hello,

I need help using tape draves as SCSI pass through on Proxmox VE 4.2. I followed the steeps to proxmox 1.x http://pve.proxmox.com/wiki/Tape_Drives but it does not work on 4.2. The operating system of the virtual machine is Suse Enterprise server 12. In my system, the device assigned to my tapes is 'sg17,sg18,sg19' etc. The model is 'Ultrium 4-SCSI' and 'D2DBS' (is a hp storeonce Backup system). I added the following line to my VM config:

scsi17: /dev/sg17 cache=writethrough

But the VM only detect the following devices:

QEMU HARDDISK
QEMU DVD-ROM

Thank you very much for your help, greetings to all.

scsi17: /dev/sg17 cache=writethrough

we only support up to 14 scsi devices so the config option should be:

scsiX: /dev/sg17,cache=writethrough

where X is a number from 0 to 13 which is not used by any other disk in the vm

Thank you very much for your answer, now it works perfectly. The vm see perfectly all drives. If anyone serves, I had to configure the VM controller SCSI as "VIRTIO", and now, its work with tape drives Ultrium LTO-3, Hp Storeonce backup, and HP Data protector.

Again, thank you very much, best regards.
