HP-UX 11i Version 2 June 2007 Release Notes

General System Administration
HP-UX WBEM LAN Provider for Ethernet Interfaces
Chapter 5
142
• The Instance Provider provides information on LAN interfaces in the system. Client
applications can use the LAN Instance Provider to determine all Ethernet LAN links
available on the system (registered and known to HP-UX DLPI) and collect
information about them.
• The HP-UX LAN Indication Provider delivers indications for events that occur on
Ethernet interfaces. Client applications can receive indications based on events
generated by Ethernet interfaces.
• The LAN Consolidated Status Provider reports the consolidated health status of the
Ethernet subsystem. Client applications can query the collection class and obtain
the consolidated health status.
Summary of Change
Two new providers are delivered into this release: HP-UX LAN Indication Provider and
LAN Consolidated Status Provider.
CAUTION LAN Indication Provider Causes Critical Resource Analysis to Return Data Critical
Result
When the LAN Indication Provider is enabled, a Critical Resource Analysis (CRA) of an
Ethernet interface will return a data critical result. The CRA is executed before
replacing the PCI online card through SAM, olrad, or the PCI attention button.
What To Do
Install Data Link Provider Interface (DLPI) patch PHNE_35545. With this patch
installed, CRA results will not be impacted by the LAN Indication Provider. DLPI patch
PHNE_35545 is available at the HP IT Resource Center: http://itrc.hp.com.
Without installing this patch you can still proceed with an online card replacement by
performing the following: review the CRA report and determine if an online operation on
the slot will be safe for the systems operation. If the output of lanadmin -p <PPA> shows
only cimprovagt for the affected PPAs (Physical Point of Attachment) then it is safe to
use olrad's force (-f) option to proceed with the replacement. See the manpage olrad
(1M) for more information on the -f option.
Impact
HP-UX LAN Provider now delivers three providers.
Installation of DLPI patch PHNE_35545 is recommended.
