root.sh failed on 2nd node when installing Grid Infrastructure

Filed under: [RAC] — Tags: , , , — zhefeng @ 12:39 pm

when i was running root.sh for the last step of grid infra installation on second node, it failed (it was success on 1st node):
root.sh failed on second node with following errors
——————————————————-
DiskGroup DATA1 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

Oracle gives the reason: when you are using multipathing storage for ASM, you have to pre-configure the oracleasm file as below:

On all nodes,

1. Modify the /etc/sysconfig/oracleasm with:

ORACLEASM_SCANORDER=”dm”
ORACLEASM_SCANEXCLUDE=”sd”

2. restart the asmlib by (except 1st node):
# /etc/init.d/oracleasm restart

3. deconfigure the root.sh settings on nodes except 1st node:
$GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force

4. Run root.sh again on the 2nd node (or other nodes)
