Description Simone Gotti 2007-03-27 15:36:04 UTC 
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.
