Monitor Description
The Fibre Channel SCSI Multiplexer monitor is designed to monitor the operation of all supported FC SCSI multiplexers on your system. If a problem is detected with a multiplexer, the monitor immediately sends an event to Event Monitoring Service, which alerts you using the notification methods defined for the monitor. Clear, concise error messages identify the problem, what caused it, and what must be done to correct it.
The Fibre Channel SCSI Multiplexer monitor employs polling event detection. At regular intervals, the monitor requests status information from each multiplexer. The monitor then analyzes the data returned to determine if a hardware problem has occurred. If an error has occurred that warrants notification, an event is generated immediately.
The monitor is launched automatically when the system is started, ensuring that all supported FC SCSI multiplexers are protected from undetected hardware failure.
Release History
HP-UX 11i v1 December 2006 release: The dm_fc_scsi_mux monitor is obsolete.
February 1999 Release: Initial release
June 2001 Release: Predictive enabled and PSM state control added.Supported Products
Fibre Channel SCSI Multiplexer Model A3308A
Special Requirements
Firmware version 3840
Resource Path
Event monitoring: /connectivity/events/multiplexors/FC_SCSI_mux
Status monitoring: /connectivity/status/multiplexors/FC_SCSI_muxMonitor Name
/usr/sbin/stm/uut/bin/tools/monitor/dm_fc_scsi_mux
PSM State Control
Controls its own PSM state with calls to PSM. The MUX will remain in the UP state unless both FC paths to the MUX do not respond. The state will then be changed to DOWN until one or both FC paths to the MUX begin to respond again.
Configuration Files
Startup Configuration File (.sapcfg)
File name: /var/stm/config/tools/monitor/fc_scsi_mux.sapcfg
Default Entries: The monitor uses the standard default monitor request entries.
Monitor Configuration File (.cfg)File name: /var/stm/config/tools/monitor/dm_fc_scsi_mux.cfg
Default settings:
POLL_INTERVAL 60 minutes REPEAT_FREQUENCY 1440 minutes (1 day) EVERITY_ACTION Notify for all levels Default Client Configuration File (.clcfg)
File name: /var/stm/config/tools/monitor/default_dm_fc_scsi_mux.clcfg
Monitors containing the client-configuration files (.clcfg) are Multiple-View enabled monitors. Client-configuration files can be used to control the text sent in text messages to specific targets (for example, to Predictive Support). The default_dm_fc_scsi_mux.clcfg applies to messages sent to all targets. Specific .clcfg files (for example, predictive_dm_core_hw.clcfg) are used to control the text sent to specific targets (in this example, to Predictive Support).
HOST_ID tags in the .clcfg files control the System Information, which is reported under the "Additional System Data" label in the event messages. If a HOST_ID tag is enabled in the *.clcfg file, then the corresponding information will appear in the event message.
HOST_IDs available for all monitors are described in the Generic Monitor Data Sheet.
DEV_ID tags in the .clcfg files control the Monitor-specific information, which is reported under the "Component Data" label in the event messages. If a DEV_ID tag is enabled in the *.clcfg file, then the corresponding information will appear in the event message. DEV_IDs available for this monitor include:
DEV_ID tag Default Description dev_fc1 physical device path to FC card 1 dev_fc2 physical device path to FC card 2 dev_wwn node WWN of the MUX box dev_prod_id HP product number, HP A3308 PSM Configuration File (.psmcfg)

Default settings:
MONITOR_RESOURCE_NAME /connectivity/events/multiplexors/FC_SCSI_mux PSM_RESOURCE_NAME MONITOR_STATE_HANDLING ALL_STATE_CONTROL DOWN_SEVERITY_THRESHOLD DOWN state only if the host cannot communicate with the MUX on either FC connection.
