wooops - its also the same with update3. it appears that the new set
of disks are ATA and not fiber (as to what the rest of our blades
i had to run /etc/init.d/PowerPath start to make the PVs visible.
now i have to figure out where should it go. that PowerPath command is
already in /etc/rc.sysinit but still drops me to the maintenance mode
during boot up if the FS is in /etc/fstab.
i think i'll file this in bugzilla.
