LVM, special files , emulex fibre channel

[Stephane Branchoux]

Hello,

I installed new emulex fibre channel driver on a redhat AS 4.0 box .I 
can see luns , make volume groups ...
but when i reboot, system can't boot  due to LVM  errors.

It seems that special files (/dev/sdc*, 
/:dev/sdd*,/dev/mapper/volgroup*)  are not auto created and i can't 
mount these filesystems.
How can i create them definively ?

When i scan scsi bus, special files are created and i can activate 
volume groups with lvm vgchange -a y VolGroup03

Or is it an initrd  problem ?
lpfc module is loaded. I have

alias scsi_hostadapter4 lpfc    in /etc/modprobe.conf
and i used :
depmod -a
 mkinitrd -f /boot/initrd-2.6.9-5.ELsmp.img 2.6.9-5.ELsmp

in /etc/grub.conf :
 kernel /vmlinuz-2.6.9-5.ELsmp ro root=/dev/VolGroup00/LogVol00 rhgb 
quiet acpi=off max_scsi_luns=128

Many thanks in advance.
