Mapping an ASM disk back to its device

When we need to know which host device an ASM disk is using.
"-p" is the key...

$ /etc/init.d/oracleasm querydisk -p DATA_04 Disk "DATA_04" is a valid ASM disk /dev/sdcn1: LABEL="DATA_04" TYPE="oracleasm" /dev/sdko1: LABEL="DATA_04" TYPE="oracleasm" /dev/mapper/DATA_04p1: LABEL="DATA_04" TYPE="oracleasm"
