Candidate ASM disks not showing

If you are in the middle of grid installation, and trying to create ASM disk group but Eligible(Candidate) disks location is empty, for example like this:Screenshot-Create Disk Group

moreover you have configured candidate disks using /etc/init.d/oracleasm and listdisks command showing the disk.

bash-3.2$ /etc/init.d/oracleasm listdisks


Then follow my steps that may help:

1. Click “Change Disk Discovery Path” button

2. Enter the path /dev/oracleasm/disks and click OK

Screenshot-Change Disk Discovery Path

3. The picture should look like this:

Screenshot-Create Disk Group-1

That’s it. GOOD LUCK!
