Description Nan Zhang 2009-07-29 03:06:21 UTC

Description of problem:
The WWNs show up correctly when the system first boots, but if I rmmod and
insmod lpfc (to change lpfc_enable_npiv, for instance), then "virsh
nodedev-dumpxml" shows all f's for the WWNs. service libvirtd restart fixes
that until the next time I reload lpfc.

Version-Release number of selected component (if applicable):
libvirt-0.6.3-11.el5

How reproducible:
Always

Steps to Reproduce:
1. # rmmod lpfc.ko
2. # insmod lpfc.ko
3. # virsh nodedev-dumpxml
  
Actual results:
The wrong WWN shows with virsh.

Expected results:
The correct WWN will show with virsh.
