After compare initramfs I have found what multipath.conf is different.
I have replaced it on system and have performed mkinitrd to replace initrams and
lvm have found /dev/VolGroup00/LogVol00

This is very strange.
I understanding what multipathd don't let access denied to lvm.

(0015830) sigru (reporter) 2012-09-26 23:50	I'm sorry, it's my fault. I haven't seen filter in /etc/lvm/lvm.conf and lvm don't seen /dev/sda with root partition. Now a have modified filter=["a\|/dev/sda.\|", "a\|/dev/mapper\|", "a\|/dev/mpath\|", "r/disk/", "r\|/dev/sd.\|", "r\|/dev/cdrom\|"] And now is ok.
