Newly created disks do not appear in v$asm_disk.

I have just created disks on a new VM after installing the grid infrastructure for 11.2.0.4. The newly created disks do not appear in ASM in the v$asm_disk view

None of those disks appear. They were created as follows:

Device "/dev/sdc1" is marked an ASM disk with the label "AD_BETA_DATA2_VSP"
