FAQs on Migration from EMS to WBEM-Based Hardware Diagnostics Solution

5. Are EMS hardware alerts supported?
EMS hardware alerts generated from OnlineDiag continue to be supported on:
• HP 9000 servers
• Intel® Itanium® Montvale processor-based HP Integrity servers and earlier
EMS hardware alerts generated by OnlineDiag are not supported on servers beyond Intel®
Itanium® Montvale processor-based HP Integrity servers. However, EMS alerts that are not
generated by OnlineDiag are not affected by the OnlineDiag discontinuance. For example,
EMS HA alerts are not affected by OnlineDiag discontinuance.
6. How is OnlineDiag treated on a guest virtual machine (VM) running on new servers
beyond Intel® Itanium® Montvale processor-based HP Integrity servers? Will the
migration result in any change?
No. On an HP virtual machine, the OnlineDiag function remains the same. HP VM does not
support the complete functionality of OnlineDiag. The OnlineDiag components running on
the HP VM detect errors that are specific to the HP VM and do not detect hardware errors
occurring on the underlying physical system. For detecting hardware errors in such cases, you
must use SFM on the underlying physical machine.
7. Why should I migrate to WBEM-Based hardware diagnostics?
OnlineDiag is discontinued on all new servers beyond Intel® Itanium® Montvale processor-
based HP Integrity servers. New features and enhancements to server hardware diagnostics
will be available only on WBEM-based hardware diagnostics solution and not on EMS-based
hardware diagnostics solution. To plan for OnlineDiag discontinuance, you must migrate
from EMS-based hardware diagnostics solution to WBEM-based hardware diagnostics
solution.

migration guide available at

8. What are the benefits of migrating to WBEM-based hardware diagnostics?
The benefits of using WBEM-based hardware diagnostics solution are:
• Provides a DMTF CIM WBEM standard compliant hardware diagnostics solution.
• Enables a unified infrastructure management by integrating with HP Systems Insight
Manager (HP SIM) and HP SMH.
• Provides remote supportability by means of integration of WBEM providers with HP
Remote Support Pack (RSP).
• Provides the health status of various hardware devices. The WBEM-based hardware
monitoring also provides the follow-the-red path for locating, isolating, and
troubleshooting hardware devices.
