Tape Libary, 2 drives

davlaw · Apr 20, 2021

Are tape libraries still WIP?

I have a script that runs mtx for zeroing out tapes before use. And seems to work with either drive.

But not sure I'm dealing with the updated pmtx dealing with a multiple drive arrangement, or the drive itself ( It was added at the same time)

get same error with either gui or cli

root@pbs172:/var/log# pmtx load 13 --changer ADIC --drivenum 1
using device /dev/tape/by-id/scsi-ADICA0C0607908_LLA
Error: load drive failed - Illegal Request, Additional sense: Invalid element address
root@pbs172:/var/log#

pmtx status --changer ADIC , resulting response

I have emptied the library, reconfigured partitions to include the drive.

Removed configs in PBS for library and drives, readd and reboot

My next step will be to do the same and make the recently added drive the only one in the library

But a bit confused that my scripts are working with mtx on the same drive

hi, what kind of changer drive do you have (model/type) ?
can you post your tape.cfg ? (/etc/proxmox-backup/tape.cfg )

davlaw · Apr 20, 2021

Changer is a Dell ML6000 (rebranded Scalar_i500), drives are 2 LTO4 SAS

root@pbs172:/etc/proxmox-backup# cat tape.cfg
changer: ADIC
export-slots 31 32 33 34 35 36
path /dev/tape/by-id/scsi-ADICA0C0607908_LLA

lto: drive0
changer ADIC
path /dev/tape/by-id/scsi-F09C7CF000-sg

lto: drive1
changer ADIC
changer-drivenum 1
path /dev/tape/by-id/scsi-F09C7CF004-sg
root@pbs172:/etc/proxmox-backup#

The changer does have a control path configuration, which I had messed with, It points to the drive1 in the tape.cfg.

But when doing this I purge the partition setup and reboot the libary and reconfigure the partition (seems to make things less confusing for the library), reconfig PBS tape setup to update/match changes.

my script to erase is rather nasty. (tweaked to my use), but I see tape.cfg is using the drives mapped to -sg#

Not thinking it would make a differance, but the sg# mapped drives are using your newer driver?

I did just try using -sg instead of the -nst drives. Just some ramblings..

So for this drive the mt command failed for the -sg drive

ok can you also post the output of

Code:

pmtx status --changer ADIC --output-format json-pretty

yeah i'm trying to find out what our driver might do wrong.

the error message:

davlaw said:
Error: load drive failed - Illegal Request, Additional sense: Invalid element address

indicates that the element address of the drive is wrong/invalid

so it seems that we read that wrong from the tape library

davlaw · Apr 20, 2021

Thanks folks, much appreciated

I'm still not beyond having done something wrong somewhere..

davlaw · Apr 20, 2021

I started to post this earlier, I have the same library mapped twice, but both to same device

Odd, its the only scsi device listed as such,

that should not harm things

i am still trying to find if we parse the info from the scsi device wrong and get a wrong element_address from it (maybe our reads are misaligned or something)
can you post the output (caution, maybe it's long) for

Code:

sg_raw -r 64k /dev/tape/by-id/scsi-ADICA0C0607908_LLA B8 10 00 00 FF FF 01 FF FF FF 00 00

this sends the raw scsi command to the drive (a 'Read Element Status')
this is basically also what mtx inquiry does

ok, it seems the forum software garbles that a bit, can you redirect the output into a file and attach that? sorry, i could have mentioned that first...

Code:

sg_raw -r 64k /dev/tape/by-id/scsi-ADICA0C0607908_LLA B8 10 00 00 FF FF 01 FF FF FF 00 00 2> output.txt

davlaw · Apr 20, 2021

Ok was worried, try again. I tried a variation of that, guess I did not have the > in the right place

dcsapak · Apr 21, 2021

hi thanks for sending the output, i found the issue in our parser. i sent a patch to the list[0] and that should land in the next version (pending review)
i guess for now there is nothing you can do besides only using one drive

davlaw · Apr 21, 2021

Thank you sir, did just that. Also was reading your post on pbs-dev

But another issue has popped up. Unable to barcode tape, with one drive. Maybe related?

Will wait for update, post new thread if it is still present. I think I have enough PBS format tapes to rotate it out (like I should be using it like this to have 4 weeks worth).

After issuing "label media" via GUI

In full disclosure, I'm still feeling "??" This config is slightly different, gui wise it might look the same. Tape library has 2 drive bays, using second one this time, unlike before was using the first one (top)

Going to clear the partition on the libary and reconfigure to the top bay. Reboot everything. I don't want to say its something like this, but I will feel better having gave it shot.

yeah you have to give it the name of the drive if the changer has multiple ones with '--drive DRIVENAME'
or export it with 'export PROXMOX_TAPE_DRIVE=DRIVENAME'

davlaw · Apr 21, 2021

Gotcha, I remember doing that with 2 drives. But drive 0 is always default correct?

Anyway, duplicated error after re-config

erase failed - Illegal Request, Additional sense: Invalid command operation code

but no default drive...

root@pbs172:/dev/tape/by-id# proxmox-tape barcode-label
Error: unable to get (default) drive name
root@pbs172:/dev/tape/by-id#

Reason I go thru this is because once the control drive was replaced but not updated in the tape library config, weirdness ensued

Tape Libary, 2 drives
