Serviceguard configuration and manageability

HP technical Webcast series: deployment optimization

Technology for better business outcomes

2007 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice

Introducing todays speaker

Jonathan Patrizio is a Senior Solutions Architect in the Highly Availability Advanced Technology Center (HA ATC) and is an expert on Serviceguard manageability. He architects mission-critical, highly available and disaster tolerance solutions on HP-UX and Linux and has been with HP for 19 years. His key responsibilities include bringing requirements from customers back to the R&D lab, driving product roadmaps and generating collateral that conveys how to effectively use the Serviceguard product portfolio.

Achieving Availability

Combination of 3 major pillars of availability

Technology
Reliable architectural components (servers, disks, network, etc.) Clustering software Middleware Data replication Management software and tools

People and Processes

Training Documentation Change control

Support Services
Rapid response time Rapid diagnosis and repair Availability of parts
HP-UX 11i v3 Training

The Mission-critical environment

Why is manageability so important?

Down-time

$$$$

Many components must work together to eliminate SPOF

A variety of different manageability interfaces to master # instances of like components Visualizing how components are connected together Rapid identification of problems

Human-error one of the most common causes of down-time

Remembering the commands After real failures, administering a recovery accurately

When disaster strikes

People panic but its crucial to manage the business for continuity

HP-UX 11i v3 Training

Manageability
Bringing order from chaos
Configuration
Creation
Configuring a new system Setting attributes affecting the startup & run-time behavior Iteratively adding, deleting or modifying components of the system

Administration

Control
Operator invoked changes to the system Control of access, who gets to do what Changing run-time behavior by modifying control attributes

Discovery & Monitoring

Observance
Finding what objects exist, how they are connected Finding the detailed attributes of the components Tracking how their attributes change over time

Troubleshooting
Making status issues stand-out Providing tools to assist with fixing problems

Comprehension, Training & Reporting

Understanding how the system works Recording a configuration

Miscellaneous
HP-UX 11i v3 Training

Simulation, auditing, compliance
