FAQs on Migration from EMS to WBEM-Based Hardware Diagnostics Solution
H FAQs on Migration from EMS to
WBEM-Based Hardware Diagnostics Solution
This document provides answers to frequently asked questions about migration from EMS-based
hardware diagnostics solution to WBEM-based hardware diagnostics solution.
1. Why is Online Diagnostics (OnlineDiag) discontinued?
OnlineDiag functions within the Event Monitoring Service (EMS) framework that employs
the HP proprietary protocol for monitoring system hardware. With increasing complexity of
hardware in the data center, there is a growing demand for simplifying IT infrastructure
management. As a result HP has introduced the next generation hardware diagnostics solution
that employs industry standard protocols for monitoring system hardware. The industry
standard protocols are Distributed Management Task Force (DMTF) Common Information
Model (CIM) and the DMTF Web Based Enterprise Management (WBEM). Because HP
wants to move away from proprietary-based hardware diagnostics solution to standards-based
hardware diagnostics solution, OnlineDiag is discontinued.
2. Is OnlineDiag discontinued on all hardware platforms?
No. OnlineDiag is discontinued on the new servers beyond Intel® Itanium® Montvale
processor-based HP Integrity servers.
Starting from the HP-UX 11i v3 March 2009 release, OnlineDiag is in the obsolescence mode
on the following HP servers:
• HP 9000 servers
• Intel® Itanium® Montvale processor-based HP Integrity servers and earlier
3. Does the scope of OnlineDiag discontinuance include EMS Framework and EMS High
Availability (HA) monitors?
No. The OnlineDiag discontinuance is limited to the OnlineDiag product that includes the
Event Monitoring Service (EMS) Hardware Monitors and Support Tools Manager (STM).
The product ID of the OnlineDiag product is B6191AAE.
4. What is the alternate hardware diagnostics solution to OnlineDiag?
System Fault Management (SFM), in conjunction with HP System Management Homepage
(HP SMH), is a standards-based solution that replaces OnlineDiag. You can use SMH plug-
ins such as evweb and SMH Property pages to obtain relevant OnlineDiag functionality on a
WBEM-based hardware diagnostics solution.
