1. Using RHEL6.5 multipath multipath software installation to configure ASM shared disk in udev mode was not successful, because there was not too much analysis and attempt at that time.

two。 Using RHEL6.5 multipath multipath software installation to configure ASM shared disk in ASMLIB mode is successful, but the following error message is reported by root.sh in the second node. The solution is shown in 3.

Disk Group CRS creation failed with the following message:

ORA-15018: diskgroup cannot be created

ORA-15072: command requires at least 1 regular failure groups, discovered only 0

ORA-15080: synchronous I/O operation to a disk failed

Configuration of ASM... Failed

See asmca logs at / u01/app/grid/cfgtoollogs/asmca for details

Did not succssfully configure and start ASM at / u01/app/11.2.0/grid/crs/install/crsconfig_lib.pm line 6912.

/ u01/app/11.2.0/grid/perl/bin/perl-I/u01/app/11.2.0/grid/perl/lib-I/u01/app/11.2.0/grid/crs/install / u01/app/11.2.0/grid/crs/install/rootcrs.pl execution failed

3. The solution is as follows

Under node1,node2:

# vi / etc/sysconfig/oracleasm

ORACLEASM_ENABLED=true

ORACLEASM_UID=grid

ORACLEASM_GID=asmdba

ORACLEASM_SCANBOOT=true

ORACLEASM_SCANORDER= "dm"

ORACLEASM_SCANEXCLUDE= "sd"

ORACLEASM_USE_LOGICAL_BLOCK_SIZE=false

# / etc/init.d/oracleasm restart

The second node executes the cleanup configuration first, and then executes root.sh:

# / u01/app/11.2.0/grid/crs/install/roothas.pl-delete-force-verbose

# / u01/app/11.2.0/grid/root.sh
