RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Harald Hoyer 2010-06-11 12:41:34 UTC
+++ 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):

udev-151-9.fc13.i686, udev-151-9.fc13.x86_64

How reproducible:

always

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

  
Actual results:

Link is missing.

Expected results:

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 ?

--- Additional comment from wd on 2010-06-10 15:42:54 EDT ---

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