2) what command is used / how to view the wwnn and wwpn for both Emulex and qlogic HBA cards?

Re: how to create a File system using LVM for disks assigned from SAN
Hi,
2) this depends on the kernel you use.
you may find them
either under /proc
or under /sys/class/scsi_host/host?
or under /sys/class/fc_host/....
identify the correct one with a glance.
3) to rescan the bus in question you can change into the found /sys/class/*host/host*/ directory and then
# echo "- - - " > scan
#dmesg should show up new devices.
4) i would first create a single partition covering the whole disk with type 8e / Linux LVM".
second "pvcreate" all the new /dev/sd*
third you either "vgextend" an existing vg or "vgcreate" a new one.
then "lvcreate" a new volume.
SEE pvcreate(1), vgcreate(1), vgextend(1), lvcreate(1)
rgds
HGH

1 and 2) Use SanSurfer utility for Qlogic and HBA Anywhere for Emulex.
