Description Daniel Berrange 2008-01-05 22:45:23 EST
Description of problem:
The /dev/disk/by-path symlink for iSCSI LUNs fails to include the lun number, so
all iSCSI luns from a particular target end up with the same clashing symlink.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Login to an iSCSI target which has multiple luns
2. Examine /dev/disk/by-path
Actual results:
Only a single link per target

# ls /dev/disk/by-path/

Expected results:
One link per LUN:

# ls /dev/disk/by-path/ip*

Additional info:
Works correctly on Fedora 8...

Fix iSCSI /dev/disk/by-path links to include LUN information

This patch is basically a diff of the /lib/udev/path_id between RHEL-5 and F-8
for the iSCSI bits. With this patch applied RHEL-5 operates correctly for iSCSI
