[Linux-cluster] GFS and EMC's powerpath

In prepping to install GFS 6.0 on a cluster of three RHEL 3, Update6 web
servers attached to an EMC AX100. I've run into some weirdness with EMC
If I have more than one server attached to the single virtual disk (i.e.
LUN) I created on the array powerpath doesn't put the pseudo device
(empowerb) into the partition table (as seen by doing a cat
/proc/partitions). If I only have single server attached/registered to
the virtual disk the pseudo device does get placed in the partition table.
I can get the EMC pseudo device into the partition table of all three
servers only by attaching and then detaching each server as I install
powerpath. Then I can attach the other two servers and things seem to
work fine...until I reboot one of the boxes. It then drops the emc
pseudo device from the partition table again.
Anyone run into similar problems?
