OCI-59313

All mirrors of the block are lost, likely due to multiple storage failures.

Cause

There were multiple failures in the storage subsystem. All redundant copies of the block were lost and Oracle wrote the hexadecimal value BADFDA7A into the block location of the lost block to signify that the block data could not be recovered from a redundant copy.


Action

Check the system logs and storage logs to identify the failure that led to the lost block.
