Ensuring SAN LUN persistent names after reboot...

Hello,

I have yet another SAN migration question. We're going to add many new
SAN LUNs, which will end up being /dev/sdp-/dev/sdas. Once the new
storage is built as md devices and added to LVM, we are going to release
the old /dev/sdb-/dev/sdo devices.

My concern is that after a reboot, the new devices will rename themselves
to /dev/sdb-/dev/sdae and it will break the md device pairing (and LVM).
Is there any way to ensure that LUN names are persistent after a reboot?

Thanks,
Arpotu
