Chapter 8 Device Polling Event

When the device polling function of this software detects the status change of the device, display it in the event as follows:

Note

When the status change of device is detected by executing [Reload Conf.] operation, the following events are not displayed.

Event	Level	Event Display	Troubleshooting
When the status changes into error	Error	Unit status changed: Error	Check the device status.
When the status has changed warning	Warning	Unit status changed: Warning	Check the device status.
When the status has changed normal	Information	Unit status changed: OK	None.
When the status has changed unmonitored	Warning	Connection Timeout	Check whether the LAN between the Management Server and the device is operating normally. Check whether the status of each device is proper, processes for network communication such as SNMP are operating, and when the device contains the server node then the Storage Cruiser's agent is operating normally on the device. If the SNMP settings of a device that uses SNMP for communication is changed, perform the following method to reconfigure the system: Refer to "Change ETERNUS Disk Storage System Information" in the ETERNUS SF Web Console Guide to change the SNMP settings.
When communication has been recovered	Information	Connection OK	None.
When error occurs in the polling function	Error	[Polling] (Error event)	Take appropriate action for each event message as follows: Command could not be executed: commandName This event occurs when command processing fails to start because of a resource shortage on the Management Server. If it is a temporary event, no special action need be taken. If it occurs regularly, however, check whether system resources (memory and file descriptors) on the Management Server have been depleted. XML File can not read: fileName This event occurs when reading of the XML definition file fails. Check for an error in the definition contents. XML File not found: fileName This event occurs when there is no XML definition file. Check for the file in the correct directory, which is specified by the directory path. Other Collect the message and other information for an investigation, and contact your Fujitsu certified service engineer.
When the access status data failed to evaluate	Error	esast5050:Failed to evaluate performance data of Tier pool (tierPoolName).	The total number of used capacity of Tier pools that can be simultaneously evaluated by ETERNUS SF Manager may possibly be exceeded. Refer to the ETERNUS SF Messages and take appropriate action according to the esast5050 message.
