Red Hat Bugzilla – Bug 603051
/dev/changer symlink not created
Last modified: 2013-10-31 21:33:41 EDT
+++ This bug was initially created as a clone of Bug #600983 +++
Description of problem:
I have several systems with SCSI Medium Changers (auto-loaders, tape libraries) attached. Up to and including Fedora 12 udev would create a "/dev/changer" symbolic link pointing to the specific /dev/sg* device. After updating these systems to Fedora 13, these links are missing on all systems.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot a system with a SCSI Medium Changer attached
2. Check that the console log contains output similar to this:
ch0: type #1 (mt): 0x0+1 [medium transport]
ch0: type #2 (st): 0x1+7 [storage]
ch0: type #3 (ie): 0x0+0 [import/export]
ch0: type #4 (dt): 0xf0+1 [data transfer]
ch0: dt 0xf0: READ ELEMENT STATUS failed
ch0: INITIALIZE ELEMENT STATUS, may take some time ...
ch0: ... finished
ch 10:0:4:0: Attached scsi changer ch0
ch 10:0:4:0: Attached scsi generic sg6 type 8
3. Check if the /dev/changer link is there:
# ls -l /dev/chang*
ls: cannot access /dev/chang*: No such file or directory
Link is missing.
Normally, /lib/udev/rules.d/40-redhat.rules would detect that a SCSI type 8 device is there and create symlinks (in the example above, "/dev/changer" and "/dev/changer-sg6").

Does it work if you change SUBSYSTEM=="scsi_device" to SUBSYSTEM=="scsi_generic" in /lib/udev/rules.d/40-redhat.rules ?

Indeed - using SUBSYSTEM=="scsi_generic" works fine for me. Thanks a lot!
