How can I determine multiple drive paths?

["Williams, Stuart Nathan (ESG - Houston)" <stuart williams2 hp com>]

I recently installed Advanced Server 3.3 onto a system.
The system has multiple drives installed, how can I determine if my
system correctly sees the drives?
I'm also interested in how to determine the hardware path from the OS
level.
I am familiar with commands in other OS's that can do this (for example
"ioscan" in HP-UX) but don't know how to do this with Linux.
Thanks.
