What version are you using?
We had exactly the same issue with Redhat 4 and PowerPath 4.5. We
managed to make it work
correctly playing with modeprobe.conf.
It seems that they fixed the installation with PowerPath 5.0 because we
don't have to change
anything to the configuration anymore after a new PowerPath installation
since we're using it.

Powerpath is loaded via kernel mods. Have a look in
/etc/modprobe.conf.pp
and /etc/modprobe.conf. All of my volumes are in the LVM, and i dont
have
any issues with those being mounted at boot, but ive not ever tried to
mount
filesystems on the devices outside of the LVM.

I have a RHEL 5 system that is trying to mount an EMC lun during boot.
When
I have it set in /etc/fstab is complains that the device doesn't exist.
If I
enter the root password it puts me into a read-only filesystem where I
can't
modify /etc/fstab. (I must boot into rescue mode using cd to fix it)
/etc/fstab:
/dev/emcpowera /u01 ext3 defaults 0
2
However, if I don't mount it via fstab and wait until the system is
booted
to mount it -- it mounts fine.
I'm guessing that powerpath is not being started early enough or its
taking
longer than it should to initialize. Im mostly a sun guy so where
exactly
should power path be started or is it somehow called from somewhere
else? Im
not even seeing an entry in /etc/rc2.d or /etc/rc3.d that starts power
path.
There is a script in /etc/init.d, but I cannot determine from where and
when
it is called, if it even is. (the script doesn't have the normal
chkconfig
run level config info near the top like most do) But somehow once the
system
is booted power path is running and the emcpowera device has been
initialized.
Unfortunately I can't use native linux multipathing on this node.
Thx for any help
