Description Daniel Berrangé 2008-01-06 03:45:23 UTC 
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):
udev-095-14.9.el5

How reproducible:
Always

Steps to Reproduce:
1. Login to an iSCSI target which has multiple luns
2. Examine /dev/disk/by-path
3.
  
Actual results:
Only a single link per target

# ls /dev/disk/by-path/
ip-192.168.122.170:3260-iscsi-demo-tgt-a
ip-192.168.122.170:3260-iscsi-demo-tgt-b

Expected results:
One link per LUN:

# ls /dev/disk/by-path/ip*
/dev/disk/by-path/ip-192.168.122.170:3260-iscsi-demo-tgt-a-lun-1
/dev/disk/by-path/ip-192.168.122.170:3260-iscsi-demo-tgt-a-lun-2
/dev/disk/by-path/ip-192.168.122.170:3260-iscsi-demo-tgt-a-lun-3
/dev/disk/by-path/ip-192.168.122.170:3260-iscsi-demo-tgt-a-lun-4
/dev/disk/by-path/ip-192.168.122.170:3260-iscsi-demo-tgt-a-lun-5
/dev/disk/by-path/ip-192.168.122.170:3260-iscsi-demo-tgt-b-lun-1
/dev/disk/by-path/ip-192.168.122.170:3260-iscsi-demo-tgt-b-lun-2


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
LUNS
