Problems accessing a SCSI Tape in a container

[smguenther]

Hello,

my intention is to use a HP Ultrium tape in a Ubuntu 18.04 container, running on a Proxmox VE 6.0.4.

During the boot process the system recognizes the scsi controller and the tape, here is the output of dmesg:

[    3.680072] scsi target5:0:3: asynchronous

"lsscsi -l -L -d" reports the tape, too:

[5:0:3:0]    tape    HP       Ultrium 3-SCSI   G2AD  -        [9:0]
  device_blocked=0
  iocounterbits=32
  iodone_cnt=0x22
  ioerr_cnt=0x1
  iorequest_cnt=0x22
  queue_depth=1
  queue_type=simple
  scsi_level=4
  state=running
  timeout=900
  type=1

According to the output of dmesg, the tape/device should be accessible via /dev/st0 but there is no such device in /dev:

console  core  fd  full  hugepages  initctl  log  lxc  mqueue  null  ptmx  pts  random  shm  stderr  stdin  stdout  tty  tty1  tty2  urandom  zero

Is that a problem of the container and how can I solve it?

Thanks for any hints and suggestions,

Stefan

Hi,

please update to the current version.
We only support the current version of Proxmox VE.

And try again.
