/etc/init.d/oracleasm querydisk <ASM Disk Label>
does not show disk number on a valid ASM disk as before. Here is an example:
With old oracleasm-support 2.0.3, it shows:
Disk "P811DATA4_VOL2" is a valid ASM disk on device [94, 177]
After upgrading to 2.1.2, it shows:
Disk "P811DATA4_VOL2" is a valid ASM disk
The device number disappeard. There could be some product applications relying on the device number output. The unavalablity of information could cause those applications get out of order.
Upgrade oracleasm-support to 2.1.0 or newer from 2.0.3 or older.
