Marking disk “VISC_PV101_DISK2″ as an ASM disk: [ OK ]

Next, you need to scan the disks on the remaining RAC nodes:
- root: /etc/init.d/oracleasm scandisks
Scanning the system for Oracle ASMLib disks:
You can verify the the disks on the other RAC nodes with the listdisks option:
- root: /etc/init.d/oracleasm listdisks
