PowerPath does not load on RH 4.0 on boot

Recently upgraded a kernel on a box.

After reboot PowerPath does not start.

Re-installed PowerPath (as it was no longer in /etc/rc.sysinit)

Even added a sleep entry (20 secs) like I have on some other boxes, but still.. no luck.

# Remount the root filesystem read-write.

update_boot_stage RCmountfs

state=`awk '/ \/ / && ($3 !~ /rootfs/) { print $4 }' /proc/mounts`

[ "$state" != "rw" -a "$READONLY" != "yes" ] && \

  action $"Remounting root filesystem in read-write mode: " mount -n -o remount,rw /

###BEGINPP

# Configure and initialize PowerPath.

if [ -f /etc/init.d/PowerPath ]; then

echo Sleeping for 20 seconds for PowerPath

sleep 20

/etc/init.d/PowerPath start
