Local Internal Hard Disk Gets Renamed Once SAN Is Attached on OL6. (Doc ID 2183093.1)

Hello colleagues. We have problem exatly as it is mentioned in

https://support.oracle.com/epmos/faces/DocContentDisplay?_afrLoop=18007918563347&id=2183093.1&_afrWindowMode=0&_adf.ctrl-state=1ic7s0yq6_4#FIX

According customer solution is not working and system still use different naming for booting disk.

I was thinking about 2 solutions:

1. Place udev rule in /etc/udev/rules.d/20-names.rules

KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=%N", RESULT==<WWID system local disk>, SYMLINK+="sda%n

OR

2. Reinistializate initramfs through the dracut.  Do you think it is necessary after addign "rdblacklist=lpfc" to kernel parameters of current active boot kernel in /boot/grub.conf also reinitializate initramfs to make it working ?
