| # DESCRIPTION: |
| # Verify that a zvol device can be used as a swap device |
| # through /etc/vfstab configuration. |
| # |
| # STRATEGY: |
| # 1. Modify /etc/vfstab to add the test zvol as swap device. |
| # 2. Use /sbin/swapadd to add zvol as swap device through /etc/vfstab |
| # 3. Create a file under /tmp and verify the file |
