Proxmox Backup on the Tapes

trbnw · Aug 14, 2024

@chybz - You might have already figured this out, but you'll need to set the "drivenum" on the first drive to '0' and the "drivenum" on the second drive to '1'

I had this working for a couple years with both set to '0' or just left blank, but on the newest version of PBS it wasn't working for me.

In the GUI you'll probably see that after clicking on your changer that you only see on of the drives even though you have added both in the 'Drives' section of 'Tape Backup'?

Hi.. worked finally. I just left 1 drive + changer .. changed drivenum=0 in tape.cfg..

I'm able to format tape..

Next pb is encryption. drives are encryped with a no-longer-existing EKMS server .. no login to remove/unconfigure that . and I'm afraid that factory reset will destroy all my licenses ...

Seems to be weird

Hi, same test. same results. "wait_until_ready failed - got timeout"

- Server id HP DL380G8 (from StoreOnce 6500)
- Library is HP ESL G3 with LTO6 Fiber (through SAN switch)
- Library partition has all resources (all slots/i-e/drives)
- 2 drives D09 and D12 are zoned with server

- changer is working from CLI and GUI
- unable to use drive : format / label
- have 2nd configuration on other site : same errors

What did I missed ?

Code:

root@bckpcy01srv14:~# proxmox-tape  label --label-text NR0013L6 --drive D09 --pool TESTPOOL
TASK ERROR: open drive 'D09' (/dev/tape/by-id/scsi-80128D0031-sg) failed - wait_until_ready failed - got timeout

It was drive encryption. We hacked the non-longer-supported-library and cracked the 'security' user account that manages encryption. That's ok now.

Next issue is now how drive are numbered

My library is an Adic i2000 branded by HP

It has partitions

For the test, I only gave 9 drives out of 12 in that partition. They appear in Linux in reverse order .. Drive 12 has the lowest SCSI number .

I can't figure out how to number drivenum in tape.cfg.

we have several drive numbering methods

Linux :

installed Drive 12, is seen as Physical Drive 23 (logical P1 D9) is the first shown on linux server, and i chose to show the media changer through that drive

which drivenum shall I set ?

Hi,

I too change the drive num to 0. Now, at least it starts backing up the datastore.
