[linux-lvm] SAN VG not active after boot

[Shea,Dan [CIS]]

SAN is an EMC device.
We are using lpcdd modules for an emc fibre optic card. 
PowerPath modules are from EMCpower.LINUX-3.0.7-007.i386.rpm
We are using Red Hat Enterprise Linux AS release 3 (Taroon Update 1).
The lvm version is from lvm-1.0.3-15.

After a reboot, the server pascal comes up and does not see the SAN partition.  It is shared between two servers.
In order to activate the SAN partition I have to vgexport and then vgimport the vg npmu_vg02.
Is there something that can be done so that it will come up cleanly?

If vgscan is run 
[root at pascal etc]# vgscan
