in my case:

oracle_at_momos_at_+ASM: ~
-bash-3.2 $ oracleasm querydisk -p vol1
Disk "VOL1" is a valid ASM disk
/dev/emcpowera1: LABEL="VOL1" TYPE="oracleasm"
/dev/sdx1: LABEL="VOL1" TYPE="oracleasm"
/dev/sdm1: LABEL="VOL1" TYPE="oracleasm"
/dev/sdb1: LABEL="VOL1" TYPE="oracleasm"
/dev/sdai1: LABEL="VOL1" TYPE="oracleasm"
/dev/sdat1: LABEL="VOL1" TYPE="oracleasm"
/dev/sdbe1: LABEL="VOL1" TYPE="oracleasm"
/dev/sdbp1: LABEL="VOL1" TYPE="oracleasm"
/dev/sdca1: LABEL="VOL1" TYPE="oracleasm"

oracle_at_momos_at_+ASM: ~
-bash-3.2 $ oracleasm querydisk -d vol1
Disk "VOL1" is a valid ASM disk on device [120, 1]
