How to identify exactly which disks on a SAN have been allocated to an ASM Diskgroup

To find the major, minor numbers of a device associated with a Diskgroup, e.g. PTTQA_BF
-------------------------------------------------------------------------------------------------

# /etc/init.d/oracleasm querydisk PTTQA_BF

Take the major,minor number set and correlate it to a device in the partitions table
------------------------------------------------------------------------------------------------------------
# cat /proc/partitions
