Description of problem: I cannot find a similar issue on bugzilla. Perhaps it's related to bug #167291. Sorry if it's duplicated. On a system with RHEL4-U4 and a lot of scsi devices the block device /dev/sdbm that has major 68 and minor 0 isn't created (noticed because multipath -l reports only 3 paths instead of 4). Looking at /etc/udev/rules.d/50-udev.rules this major is forced to be called capi20: SYSFS{dev}="68:0", NAME="capi20" [root@itradedb03c ~]# udevinfo -q all -p /block/sdbm P: /block/sdbm N: capi20 T: b M: 060660 S: O: root G: uucp F: /etc/udev/rules.d/50-udev.rules L: 67 U: 2834 R: 0 Removing this line fixed it. Version-Release number of selected component (if applicable): udev-039-10.15.EL4 How reproducible: The system was just installed didn't rebooted. But I think it'll always happen. Actual results: /dev/sdbm (the block device that has major 68 and minor 0 isn't created because overrided by /dev/capi20) Expected results: /dev/sdbm created.

Simone, it looks like IBM has already found this issue and is working to resolve this for RHEL 4.6. *** This bug has been marked as a duplicate of 202792 ***
