similar to: Fw: Error attaching tape drive device to KVM guest

Hello, i'm trying to configure a host SCSI device (tape drive) so that it is available in a KVM guest VM, but am receiving an error when attempting to attach the device. My guest xml has the following scsi controller defined: <controller type='scsi' index='0' model='virtio-scsi'> <alias name='scsi0'/> <address type='pci'

Hi, For some time now (starting with the 3.10 or 3.11 kernels, but I'm not sure) I have the following problem: I have a machine with 6 SATA slots and two SAS controllers, one onboard HBA and one RAID controller in a PCIe slot. The problem is that the order of the SAS controllers changes randomly after a reboot, so the SCSI addresses of the devices change. One time lsscsi prints (empty

Hi All, I have a Quantum scalar i40 tape library. I need to configure it to TWO tape partition libraries, e.g., library_a and library_b, so that each library has its own tape drive. Then connect this physical tape library to two different CentOS servers so that each server can see its own media changer and tape drive. I once had a successful configuration on one host but NOT on the other. One

Hi, John, and thank you! This was a very thorough and welcome response, I was wondering where all the storage guys were... I will get back to you with more details later, specifically about multipath, since this needs to be investigated thoroughly. I have, with trial and error method, during the elapsed time, been able to attach the NPIV pool LUN to a virtio-scsi controller, and it seems it

Hi, Hi, I have been googling, and can't find anything that will help me: mt -f /dev/st0 status /dev/st0: No such device or address Any suggestion?

I just got an error using star to send an archive to tape. I know the tape works--I tested it with gnu tar yesterday. But when trying find /home -mount -depth -type f | star -c list=- -z f=/dev/st0 I got the error: star: can only copy files When I wrote to the tape with tar yesterday, tar -zcvf /dev/st0 /home/matt worked fine. And that star command works when the output destination if a file

Hi again! Need to add here, since I been investigating a bit further, that it seems to be possible to add an NPIV vhba to the guest, using vdsm hooks. I've seen the reference to "host device assignments", which Dan pointed me too, but I didn't really understand the meaning of it at that moment. It would be interesting to hear from someone that have been doing it, how it would

hi all, i want to use a compaq sdlt 320 under centos. the tape drive was already installed and after rebooting i was not able to see it(dmesg | grep tape or dmesg | grep scsi). i add the correct module (modprobe st) but i'm not able to use with mt. the st0 file is missing, can someone help to resolve this issue. thanks ?

Hi! Report from my multipath tests today. My test virtual machine, that runs from an NPIV pool, is not able to use multipath. When I pulled the cable from one of the targets, it crashed. But, strangely, it could boot up again on that other path, that it just crashed on. That tells me it can use both paths, and is not limited to one of them only, but because the multipath layer isn't

I've taken you as far as I can go. ?Now you will have to experiment a bit for your use case. ?I should point out that at least in my system, the link with the serial number in it shows up even with the line commented in the rules file. As always, YMMV. On Thu, 2019-02-07 at 22:29 +0100, Helmut Drodofsky wrote: > Hello Ron, > > sounds good. I have 2 tape changer. I persume, udev

Anybody know, how I can hook up my tape drive (which is /dev/st0 on my LINUX box) so that I can do remote backups through samba for my WinNT/95 LAN? Thanx' Adrian Lattke

Hello, I want to backup my PE2800 on tape but I'm not sure how to do this. My PE2800 has a RAID5 setup with 2 72GB SCSI disks and a Seagate DAT-2 72GB internal tape-streamer and I'm running Centos 4.3 with the latest yum updates. I'm not sure if this tape-streamer is recognised by the OS properly because it doesn't show up along with my DVD/floppy I also recieved with the

Hello Ron, sounds good. I have 2 tape changer. I persume, udev creates the same link for both. Can I modify SYMLINK+="changer-$env{ID_SERIAL}" The serial should be unique.

Hi, after installing centos 4.2 I've noticed that my internal Seagate scsi DAT 72GB tape drive hasn't been recognised in /media or doesn't show up in gnome when putting in a tape.

Hello! I'm having problems with udev /dev/tape/by-id/ symlinks.. it seems symlinks to tape drives are sometimes (randomly) missing after reboot. Server in question has IBM TS3200 tape library connected with 2 drives in it.. so /proc/scsi/scsi shows 3 devices: 2 tape drives, and 1 medium changer (tape library). So I should have 3 symlinks in /dev/tape/by-id/ directory.. 2 symlinks to tape
