ASM Crash by GMON Due to ORA-600 [KFDPHBEAT_REAPIO:02] (Doc ID 2106160.1)

Last updated on OCTOBER 31, 2016

Applies to:

Oracle Database - Enterprise Edition - Version 12.1.0.1 and later
Information in this document applies to any platform.

Symptoms

One of our ASM instances crashed causing database instances to restart on 1 node.

The 'alert+ASM1.log' file shows that diskgroup EEPERF2_REDO was mounted when
'gmon' reported an ORA-600 error in the I/O function [kfdpHbeat_reapIO:02] on EEPERF2_REDO.

In companion with the internal error (ORA-600) we see a corruption in the asm block header reported (ORA-15196).
After asm instance rebounce, no disks are available for EEPERF2_REDO. The diskgroup cannot be mounted anymore.
