OEL 4.7 cannot detect all luns from XP24k

[Hui Liu]

Evn.:
XP24k+ san switch MDS +C7000+ BL680c+ OEL4.7+ Emulex LPe1105
without any multipath software install yet.

Isuue:
Mapping 8 luns(256GB each) to the OEL OS. but just find only one lun with 4 paths(/dev/sda,/dev/sdb,/dev/sdc,/dev/sdd)

++++the output for XP24k lun mapping++++++++

the following pdf says "XP luns present to linux must start with LUN 0"
http://h50146.www5.hp.com/products/software/oe/linux/mainstream/support/doc/option/fibre/pdfs/c01831335.pdf

Is that true? the LUN ID can only be 0000/0100/0200/.....??
How can I use the OS and DB with different XP luns to enhance the IO performance?

many thanks
