Rapid Error Recovery
Compaq servers provide rapid recovery services for diagnosing and recovering from errors.
These tools are available for local and remote diagnosis and recovery.
Rapid recovery means fast identification and resolution of complex faults. The Rapid Recovery
Engine and Insight Management Agents notify the system administrator when a failure occurs,
ensuring that the server experiences minimal downtime. These integrated server management
features are:
■ Automatic Server Recovery (ASR)
■ Integrated Management Log (IML) Messages
■ Storage Fault Recovery Tracking
■ Storage Automatic Reconstruction
■ Network Interface Fault Recovery Tracking
■ Memory Fault Recovery Tracking
These are discussed in more detail on the server documentation CD.
Automatic Server Recovery
Automatic Server Recovery (ASR) lets the server restart automatically after a catastrophic
operating system failure.
The available recovery features are:
■ Software Error Recovery—automatically restarts the server after a software-induced
server failure
■ Environmental Recovery—allows the server to restart when temperature, fan, or
AC power conditions return to normal
Unattended Recovery
For unattended recovery, ASR performs the following actions:
■ Logs the error information to the IML
■ Resets the server
■ Tries to restart the operating system
Often the server restarts successfully, making unattended recovery the ideal choice for remote
locations where trained service personnel are not immediately available. The Server
Management Driver (the Health Driver) automatically enables ASR when the driver is loaded.
