Root.sh second rac node DG_GRID creation failed with the following message: ORA-15018: diskgroup cannot be created ORA-15031: disk specification '/dev/rhdisk37' matches no disks ORA-15025: could not open disk "/dev/rhdisk37" ORA-27041: unable to open file

If you run root.sh on second node while installing grid infrastructure 11g and got this error below:



Disk Group DG_GRID creation failed with the following message:
ORA-15018: diskgroup cannot be created
ORA-15031: disk specification '/dev/rhdisk37' matches no disks
ORA-15025: could not open disk "/dev/rhdisk37"
ORA-27041: unable to open file

Check if you can see all the same disks on both nodes using this command below:

--Run on both nodes

kfod asm_diskstring='/dev/rhdisk37*' disks=all

--To check all disks on run on both nodes

kfod asm_diskstring='/dev/rhdisk*' disks=all

If you cannot see, ask Storage Administrator to see why disk is not there and they must fix it before you run root.sh on second node again.
