How to verify a raw partition contains Oracle data

[sunhux G]

Hi,


We have just presented quite a few SAN disk partitions to
a couple of of our Redhat servers.

However, since the SAN is a shared resource, we need a
way to verify that there's certainly no data in the raw SAN
partitions, in particular Oracle data/database.

"/usr/bin/raw -qa "  returns nothing.

Is there some sort of Oracle or tools that I can use?
As it's raw partition, "ls /partiton_name"  won't help

THanks
U


Thanks
