Symptoms

While installing Oracle Grid Infrastructure with ASM, root.sh ran successfully in first node,
but fails on the second node.

Error example

1. root.sh failed on second node with following errors
-------------------------------------------------------
DiskGroup <DG_NAME> 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


Configuration of ASM failed, see logs for details


2. rootcrs_nodename.log
-----------------------

3. On the 2nd node
/etc/oratab files shows +ASM1, rather than +ASM2

4. The following commands on the 2nd node show the ASM disk information correctly
/etc/init.d/oracleasm listdisks
/etc/init.d/oracleasm scandisks
ls -ltr /dev/oracleasm/disks
