Hi Pedro, Thanks for the link. I actually looked at it before Hartge responded and funny enough came to the same conclusion. The info maps the tape nicely but I don't get enough info from udev to do the dame with autochanger.
I only get this: [root@eng-backup01 etc]# udevadm info --name=/dev/sch0 --query=all P: /devices/pci0000:40/0000:40:02.0/0000:42:00.0/host1/port-1:0/end_device-1:0/target1:0:0/1:0:0:1/scsi_changer/sch0 N: sch0 E: DEVNAME=/dev/sch0 E: DEVPATH=/devices/pci0000:40/0000:40:02.0/0000:42:00.0/host1/port-1:0/end_device-1:0/target1:0:0/1:0:0:1/scsi_changer/sch0 E: MAJOR=86 E: MINOR=0 E: SUBSYSTEM=scsi_changer Regards, William ________________________________________ From: Sven Hartge <s...@svenhartge.de> Sent: March 3, 2019 10:21 AM To: bacula-users@lists.sourceforge.net Subject: Re: [Bacula-users] Persistent device name for autochanger On 03.03.19 16:00, Pedro Oliveira wrote: > https://nonhazardo.us/tape/storage/udev/2016/03/14/udev-persistent-tape-drive-naming.html This is all well and fine, but only talks about /dev/stX and /dev/nstX. But persitently naming the tape devices is not the question here. The real question is on how to peristently name the *generic* SCSI device associated with the tape changer. The values you get inside udev for scsi_generic are rather sparse: P: /devices/pci0000:00/0000:00:01.1/0000:02:00.0/0000:03:04.0/host6/target6:0:2/6:0:2:0/scsi_generic/sg5 N: sg5 L: 0 E: DEVPATH=/devices/pci0000:00/0000:00:01.1/0000:02:00.0/0000:03:04.0/host6/target6:0:2/6:0:2:0/scsi_generic/sg5 E: DEVNAME=/dev/sg5 E: MAJOR=21 E: MINOR=5 E: SUBSYSTEM=scsi_generic E: USEC_INITIALIZED=29531657 Nothing really helpful to base a rule on, IMHO.
