EVWEB

EVWEB is a component of SFM that enables you to administer and view WBEM indications generated on the local system on which SFM is installed. For more information on EVWEB, see “Evweb Overview”.

EMT

EMT is a component of SFM, which contains most errors that can occur on the HP-UX 11i v3 system. You can view these error messages using HP SMH on the local system. For more information on EMT, see “EMT Overview”.

CIMUtil

SFM introduces the CIMUtil command. Using CIMUtil, you can enumerate instances related to various devices and create filters, handlers, and subscriptions supported by SFM. For more information, view CIMUtil manpage. See "man CIMUtil"

IPMI Event Viewer

Starting March 2009 release, the IPMI Event Viewer will be delivered as part of SysFaultMgmt. In the earlier releases it was delivered as part of Online Diagnostics bundle .IPMI Event Viewer is used to display low-level system log information.

Providers

SFM providers are components of SFM that retrieve information about the inventory on a system and the events that occur on the hardware resources. SFM providers can be classified as instance providers or as indication providers. This section describes SFM providers.

Instance Providers

On request, an SFM instance provider dynamically queries the local or remote system for the property information described in Table 1-1 and reports the information to the CIMOM.

Table 1-1 Instance Providers

Instance ProviderDescription

Firmware Revision

The Firmware Revision Provider retrieves the following types of information:

  • System firmware revision

  • Management Processor (MP) firmware revision

DAS Provider

Starting with HP-UX 11i v3 March 2009 release, SFM does not monitor information of storage disks or disk enclosures. However, inventory details of direct attached storage disks and error monitoring is done by DAS Provider

For information, see HP-UX WBEM Direct Attached Storage (DAS) Provider at the following location http://docs.hp.com/en/netsys.html#HP%20WBEM%20Providers

Management Processor

Retrieves information about the management processor on the system.

Enclosure

The Enclosure Instance Provider retrieves the following types of information:

  • Onboard Administrator (OA) description

  • OA IP address

  • OA MAC address

  • URL to launch the OA

NOTE: The Enclosure Instance Provider is available on BL860c HP Server Blade only.
Temperature Sensor

The Temperature Sensor Provider retrieves the following types of information: Describes properties such as sensor number, current temperature reading, and temperature sensor status.

  • Sensor number

  • Current temperature reading

  • Temperature sensor status

  • Processor temperature

  • Memory board temperature

Record Log

Enables event analysis tools such as Web-Based Enterprise Services (WEBES) to access details of indications generated by the SFMIndicationProvider that are available in the SFM database, for event analysis. The provider also supports MCA logs. Event analysis tools can access MCA log details for event analysis.

NOTE: There is no GUI for the Record Log Provider. You can only enumerate instances using the CLI.
ComputerSystem Chassis Provider

Retrieves properties such as the serial number, product ID, and virtual Universally Unique ID (UUID). It provides the following details related to the physical system:

  • SerialNumber

  • ProductId

  • Model

The ComputerSystem Chassis Provider provides the following details related to the logical server:

  • VirtualSerialNumber

  • VirtualUUID

These values are retained when an OS instance is moved to another server.

For a list of SFM indications and their details, see the SFM Event Descriptions at: http://docs.hp.com/en/diag/sfm/sfm_summ.htm

 

Indication Providers

SFM includes three indication providers, the EMS Wrapper Provider, SFMIndicationProvider, and the Event Manager Common Information Model (EVM CIM) Provider. Table 1-2 describes the SFM indication providers.

Table 1-2 Indication Providers

Indication ProviderDescription
EMS Wrapper Provider

The EMS Wrapper Provider does the following:

  1. Converts hardware events generated by the EMS Hardware Monitors into WBEM indications.

  2. Reports the WBEM indications to the CIMOM. Using a WBEM-based management application, such as HP SIM, you can subscribe to and receive Event Monitoring Service (EMS) events generated on a remote system. On the system on which SFM is installed, you can use an SFM tool, called EVWEB, to view and administer events through the HP SMH interface.

The following EMS Hardware Monitors are supported on HP 9000 servers running the HP-UX 11i v3 operating system:

  • LPMC (now CPU) (lpmc_em)

  • Memory (dm_memory)

  • Core HW (dm_core_hw)

  • Chassis Code (dm_chassis)

  • Disk (disk_em)

  • Integrity Core Hardware Monitor(ia64_corehw)

  • IPMI Forward Progress Log Monitor (fpl_em)

The following EMS Hardware Monitors are supported on HP Integrity® servers running the HP-UX 11i v3 operating system:

  • Corrected Platform Error Monitor (cpe_em)

  • IPMI Forward Progress Log Monitor (fpl_em)

  • CMC Monitor (cmc_em)

  • Itanium Core Hardware Monitor(ia64_corehw)

  • SCSI Disk Monitor (disk_em)

  • Itanium Memory Monitor (memory_ia64)

For a list of WBEM indications and their details, see the EMS Event Descriptions at:

http://docs.hp.com/en/diag

EVM CIM Provider

The EVM CIM Provider does the following:

  1. Converts hardware, software, and kernel events generated by the EVM into WBEM indications.

  2. Reports the WBEM indications to the CIMOM. Using a WBEM-based management application, such as HP SIM, you can subscribe to and receive EVM events generated on a remote system. On the system on which SFM is installed, you can use an SFM tool, called EVWEB, to view and administer events through the HP SMH interface.

SFMIndicationProvider

The SFMIndicationProvider generates indications that are compliant with the WBEM standards. On HP Integrity systems, it replaces the following EMS monitors:

  • cmc_em

  • cpe_em

  • memory_ia64

  • fpl_em

  • ia64_corehw

On HP 9000 systems, it replaces the following EMS monitors:

  • fpl_em

  • ia64_corehw

You can choose to use either the SFMIndicationProvider or the EMS monitors that it replaces, to monitor your hardware. The remaining EMS monitors continue to function as usual irrespective of whether you choose the SFMIndicationProvider or the EMS monitors that it replaces. If you choose the SFMIndicationProvider, it does the following:

  1. Generates WBEM indications equivalent to the events that the monitors it replaces generate.

  2. Reports these WBEM indications to the CIMOM.

In the WBEM indication details, the provider name displayed corresponds with the device to which the indication is related. For example, if the name of the provider displayed in the event details is MemoryIndicationProviderIA, the event is related to memory. For a complete list of the names of providers displayed in the WBEM indication details, in the SFM mode, see Table 4-2. The provider names indicate the device to which the event is related.

For a list of WBEM indications and their details, see the EMS Event Descriptions at:

http://docs.hp.com/en/diag/ems/eme_summ.htm

MCA Indication Provider

The MCA Indication Provider generates an indication when Machine Check Abort (MCA) logs are present due to an MCA.

 

NOTE: The following apply to indication providers:

  • The terms events and indications are used interchangeably.

  • Although both EMS Wrapper Provider and EVM CIM Provider generate events related to system hardware, the nature of events are different.

CIMOM identifies the SFM providers using SFMProviderModule. If a provider is not working properly, SFMProviderModule stops all the SFM providers. Starting with the HP-UX 11i v3 February 2007 release, SFM includes the cron job. Every 15 minutes, the cron job checks if SFMProviderModule is running. If SFMProviderModule is not running, the cron job starts SFMProviderModule which in turn starts all the providers.
