On this 4th scenario we lose the Voting Disk.
The Voting Disk in this case is located on a Raw Device, so backup and recovery from and to a Raw Device is explained.
To simulate the Voting Disk loss we
write zeros to the raw device, this will cause CRS to fail, the database to crash and the server to get stuck.
The Voting Disk and the OCR can and should be multiplexed.
To multiplex a voting disk execute as root:
crsctl add css votedisk <path>
The recovery steps include:
- Reboot both servers
- Restore the Voting Disk from backup
- Restart CRS
- Restart all cluster components
- Check
Important! : Before running a crash scenario be sure to Backup the Voting Disk, details to backup it are included on the attached file.
