Overview

Included with the OnlineDiag bundle of support tools are the EMS Hardware Monitors, an important set of tools for maintaining system availability. The EMS Hardware Monitors allow you to monitor the operation of a wide variety of hardware resources and be alerted immediately if any failure or other unusual event occurs.

Hardware event monitoring provides a high level of protection against system hardware failure. By using hardware event monitoring, you can eliminate the most undetected hardware failures that could interrupt system operation or cause data loss.

The following monitors are introduced in this release on PA-RISC and Itanium-based systems:

DS2500 Enclosure Monitor (gazemon)

SCSI Tape Devices (dm_stape)

The following monitor is introduced in this release on Itanium-based systems:

Emulex PCI-e Fibre Channel Mass Storage Adapter (dm_fclp_adapter)

Configuring Hardware Monitoring

The EMS Hardware Monitors are installed at the same time as the Support Tools Manager (STM). Once the monitoring software is installed, monitoring is automatically enabled.

By default, event messages with severity levels major warning, minor warning, serious, or critical generated by the monitors are conveyed in the following ways:

Written to /var/adm/syslog/syslog.log
Sent to EMAIL address root
All events generated by all the monitors are stored in the /var/opt/resmon/log/event.log file.
To configure, enable, or disable hardware event monitoring, run the /etc/opt/resmon/lbin/monconfig monitoring request manager.

The Peripheral Status Monitor (PSM) and the Kernel Resource Monitor (krmond) are configured differently. They use the Event Monitoring Service (EMS) Graphical User Interface (GUI). For more information, see:
http://docs.hp.com/en/diag/ems/ems_gui.htm

Changes

Changes made to the EMS Hardware Monitors for the June 2007 release include the following:

Changes to Monitors
Changes to Platform and Interface
Customer-Viewable Interface Changes

Changes to Monitors
This section describes the changes made to individual monitors. Monitors are listed in alphabetical order.

Chassis Code Monitor (dm_chassis)
The following change applies only to PA-RISC-based systems:

JAGag28140
The dm_chassis reports old events when the process table is full. This problem is fixed.

CMC Monitor (cmc_em)

Not applicable

Core Hardware (dm_core_hw)
The following change applies only to PA-RISC-based systems:

JAGag28139
The dm_core_hw monitor now supports the following systems:

rp7440

rp8440

9000/800/SD16

9000/800/SD32

9000/800/SD64

Core Hardware for Itanium (ia64_corehw)
The following change applies to PA-RISC and Itanium-based systems:

JAGag07766
The ia64_corehw monitor does not generate events when the SENSOR_RESCAN_INTERVAL condition is met. This problem is fixed. The monitor now generates reminder events.

Core Hardware Monitor - Asama (ipfcorehw_asama)

Not applicable

Core Hardware Monitor - Hitachi (ipfcorehw_hitachi)

Not applicable

CPE Monitor (cpe_em)
The following change applies only to Itanium-based systems:

JAGag19632
The cpe_em monitor incorrectly generates Event 100299 when a memory error corresponding to double chip sparing is encountered. This problem is fixed.

JAGag24589
Event description of events 100220 and 100221 indicates that the cell is faulty. This description is incorrect. The event description is modified to fix the problem.

CPU Monitor (lpmc_em)

Not applicable

CPU Monitor - Hitachi (cmc_em_hitachi)

Not applicable

Disk Array FC60 Monitor (fc60mon)
Not applicable

Disk Monitor (disk_em)

Not applicable

DS2500 Enclosure Monitor (gazemon)

The DS2500 monitor is supported in this release on PA-RISC and Itanium-based systems.

The following change applies to PA-RISC and Itanium-based systems:
JAGag30664
The gazemon monitor generates duplicate disk_em asynchronous events. This problem is fixed.

Fibre Channel Adapter (dm_ql_adapter)

Not applicable

Fibre Channel Adapter Model A5158 Monitor (dm_TL_adapter)

Not applicable

Fibre Channel Switch (dm_fc_sw)

Not applicable

Forward Progress Log (FPL) Monitor (fpl_em)
The following changes apply to PA-RISC and Itanium-based systems:

JAGag15659
The Time Stamp of Event 676 is incorrect. This problem is fixed.

JAGag02230
The fpl_em monitor does not generate pre-boot events. A new value, PRE_BOOT_FLAG, is added in the global config file (fpl_em.cfg) to fix this problem.

High Availability Disk Array Monitor (ha_disk_array)

Not applicable

High Availability Storage System (dm_ses_enclosure) The following change applies to PA-RISC and Itanium-based systems:

JAGag35642
Event 601 and Event 603 are reported incorrectly. This problem is fixed.

iSCSI Driver Subsystem Monitor (dm_iscsi_adapter)

Not applicable

Kernel Resource Monitor (krmond)

Not applicable

Memory (dm_memory) The following change applies only to PA-RISC-based systems:

The dm_memory monitor now supports the following systems:

rp7440

rp8440

9000/800/SD16

9000/800/SD32

9000/800/SD64

Memory IA64 (memory_ia64)
JAGaf23487
Event 1400 is generated when the PDT is 100% full. This event is new.

JAGag28127
DRAM erasure events are generated when an erasure occurs. Double Chip spare events such as events 5000, 5100, 5200, 5300, 5400 are disabled to fix this problem.

JAGag28128
Event 6100 is generated when 24 errors occur in 24 hours on the entire system. The event is now generated when 24 errors occur in 24 hours only on a single extender and not on the entire system.

Memory Monitor -- Hitachi (ipfmemory_hitachi)

Not applicable

MSA1000/MSA30 Storage Disk Array Monitor (msamon)

JAGag24840
The EMS GUI cannot identify the /storage/status/disk_arrays/MSA1000 path. Therefore, the PSM does not monitor the StorageWorks Modular SAN Array 1000/30 (MSA1000/MSA30). This problem is fixed.

Not applicable

Known Problems
If the System Fault Management product is installed on your system, you must complete the following steps, before and after updating the OnlineDiag product:
Type the following command to shut down the System Fault Management subsystem:
       # /sbin/init.d/cimserver stop
Perform the OnlineDiag update.
Type the following command to restart the System Fault Management subsystem after the update is completed:
       # /sbin/init.d/cimserver start
If the maxssiz_64bit kernel parameter is set below the default value of 0x800000, it can cause the lpmc_em monitor to abort.
The Memory Page Deallocation (MPD), which runs on most current HP-UX systems, does not work on rx4610 systems. The activity log for memlogd includes a message that reads unsupported device.
MPD cannot be implemented on the rx4610 system because the system's design does not allow the memlogd daemon to run on it.
