ASM instance: ORA-15032 and ORA-15063 errors occur after restart of the Host
We already had the same symptom of ORA-15032 & ORA-15063 mentioned in my last post . Trying to follow these instructions didn't help this time. ls -l /dev/oracleasm/disks/* rpm -qa | grep oracleasm kfod asm_diskstring='ORCL:*' disks=all /etc/sysconfig/oracleasm conatin ORACLEASM_SCANORDER=dm spfile has: asm_diskstring = /dev/dm* All of these command worked fine. Beacause of the dm* parameter I checked the filesystem: $ ls -l /dev/dm-* /bin/ls: /dev/dm-*: No such file or directory It seems that the dm* devices are missing and must be there for ASM by Note 602952.1 : NOTE: When scanning, only the device names known by the kernel are scanned. With device-mapper, the kernel sees the devices as /dev/dm-XX. The /dev/mapper/XXX names are created by udev for human readability. Any configuration of ORACLEASM_SCANORDER or ORACLEASM_SCANEXCLUDE must use the dm prefix. Since this Host is RedHat 5, we found the source of the problem by Note 558596.1: Cause: The oracleasm scans /p
