Last updated on APRIL 29, 2020

Applies to:

Linux OS - Version Oracle Linux 5.3 to Oracle Linux 5.3 [Release OL5U3]
Linux OS - Version Oracle Linux 4.8 to Oracle Linux 4.8 [Release OL4U8]
Oracle Cloud Infrastructure - Version N/A and later
Information in this document applies to any platform.
Linux Kernel - Version: 5.3 to 5.3
This problem can occur on any platform.


Symptoms

The command:

/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:

#/etc/init.d/oracleasm querydisk P811DATA4_VOL2
Disk "P811DATA4_VOL2" is a valid ASM disk on device [94, 177]


After upgrading to 2.1.2, it shows:

/etc/init.d/oracleasm querydisk P811DATA4_VOL2
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.

Changes

Upgrade oracleasm-support to 2.1.0 or newer from 2.0.3 or older.
