Hi All,

Pardon me in case the below error has been encountered previously. While performing the runcluvfy checks i am facing the sharedness of the disk could not be determined. Kindly assist.

Below are the complete configuration details :
OS - OEL 6.1 , NODE1,NODE2

Grid infrastructure - 11.2.0.3


NODE1 : Oracle RPM installed: rpm -qa |grep -i oracleasm

oracleasmlib-2.0.4-1.el6.x86_64
oracleasm-support-2.1.5-1.el6.x86_64



NODE2: Oracle RPM installed: rpm -qa |grep oracleasm
oracleasmlib-2.0.4-1.el6.x86_64
oracleasm-support-2.1.5-1.el6.x86_64


NODE1 :
id grid
uid=60000(grid) gid=11001(oinstall) groups=8500(dba),59031(asmadmin),59032(asmdba),59033(asmoper),11001(oinstall)

NODE2 :
id grid
uid=60000(grid) gid=11001(oinstall) groups=8500(dba),59031(asmadmin),59032(asmdba),59033(asmoper),11001(oinstall)


Storage provided as LUNS

/dev/sda 4294 MB


[root@NODE1 ]# ls -tlr /dev/sd[a-n]
