Oracle encountered an I/O error when performing an action

ORA-15081: failed to submit an I/O operation to a disk

There was an error when Oracle had to do an I/O operation.

Typically this means a disk failure, and you should check your event viewer on Windows or your /var/log/messages on Linux to see which is the failing disk.

Check for:

  • disks which are offline
  • failed raids
  • disk block corruption
  • Network cables to your storage server which are disconnected
  • broken fiber channel cards
