Sanjay,

X$KFFXP is the view you're probably looking for.

See this article by Luca Canali of CERN, for some ideas on how to interpret/use 
it:

Hope that helps,

Subject: ASM disk mapping to segment

Hi

Can someone shared the script to map as what Oracle Database segment is located 
on particular ASM Disk in the Diskgroup ? We have 5 disk out of 40 disk in a 
diskgroup that are reported as high IO. As same diskgroup is shared among 5 
database and so need to find what are different segements at this particular 
disk from multiple databases.

Thanks
Sanjay
