• Create ASM devices of various types
• Create and managing disk groups
• Relocate, and, and remove voting files
• Add OCR mirrors
• Backup, restore, export, and import the OCR
• Simulate and recover from disk failures
• Create and use ACFS volumes
• Configure ACFS snapshots, replication, and encryption
