ASM disks not on cluster

Had an issue where I used the command line to add two candidate disks to create an ASM disk group. However, when using the 'dbca' utility to create a database. kept hitting an issue where the disk group was only showing on one node on the cluster.

Think I hit a "wood for trees" moment and should have just logged into the second ASM instance and ran a "alter diskgroup DATA2  mount;" but like I say ended up scratching my head.

After a few minutes to contemplate I ran the 'asmca' utility and thought there must be a way to do this. It is not obvious but if you right click on the disk group you get a load of options, one being to mount the disks (or click the option at the bottom of the page) and as if by magic after one click everything was showing up. Had I not hit the issue I would have continued to run everything from the command line yet the graphical interface is so much better (even though good to know both).

From my test RAC cluster :
