A special rescue configuration checkpoint can be created that an operator can rollback revert to at any time. The rescue configuration has its own keyword (rescue) and does not use the same rolling suffix indexes as the normal rollback checkpoints. This allows the operator to easily return to the rescue configuration state without having to consider a checkpoint index, and ensures that the rescue checkpoint is always available (does not roll off the bottom of the list of checkpoints).
The operator should define a basic rescue configuration that is known to work and give correct management access to the node.
The location and filename of the rescue file are configurable. The 7210 SAS appends an .rc suffix to the specified rescue filename.
