How to verify a raw partition contains Oracle data

[sunhux G]

Just to add on a couple more questions :


The SAN partitions are "/dev/sdh, /dev/sdv ... " & "fdisk -l"
will not quite show them properly.

Two other side questions :
1) A colleague who has left told me to let the DBA (an outsourced
    vendor) to use /dev/mpath/mpath0   or  have I misquoted my
    colleague

2) Do I need to reboot the Linux servers before the raw partitions
    can be used?

Thanks
U
