Viewing System Parameters
The Serval filer contains different System parameters that can be displayed for information about the contents of hardware installed in the Serval filer, the location of the different hardware components, the current admin users that can access the Serval and their access privileges, and so on.
Viewing the System Report
The Serval Filer enables you to view an on-demand report of system parameters and the Serval chassis configuration.
Figure 10 shows the Filer Report window where system parameters and chassis configuration information is tracked.
Figure 10 Filer Report display
The Chassis Configuration display gives you at-a-glance information about the slots and their runtime parameters.
Table 4 shows the contents of the Filer Report display.
Table 4: Filer Report display
Field
|
Means
|
Slot
|
The slot numbers that the runtime software recognizes. This field contains a link that invokes the second of the Filer Report displays, the Slot Configuration display.
|
Module
|
The type of module installed in each slot. Valid values are:
- SSC for the System Switch and Controller module
- FPNIM for the Gigabit Ethernet File Processing module
- SPNIM for the FibreChannel Storage Processing module
|
Power
|
The power indication for the slot. This field indicates whether the Serval Filer's power supplies are providing power to a particular slot by determining the voltage being supplied through the backplane, either +3.3, + 5, or + 12 V. If this field is blank, then the Serval Filer cannot determine a valid voltage from the backplane.
|
Temperature
|
The ambient temperature, in number of degrees centigrade (ºC), in each slot. If the temperature sensor cannot determine a slot's temperature, then this field is blank.
|
Version
|
The version string for the software image currently running on the module listed in the Module field.
|
Operation
|
The operational state of the module's processor. Valid states are:
- Up, for components that have successfully booted and are operating correctly.
- Down, for components that have not booted.
- Unknown, for components that have an operational state that cannot be determined.
- PROM, for components that are in boot PROM mode.
|
On the Chassis Configuration display of the Filer Report, the
Slot field contains links to detailed information about what is installed in a particular slot. If you click the link in the
Slot field, you invoke the Filer Report Slot Detail display.
Figure 11 shows this display.
Figure 11 Filer Report, Slot Detail display
The Slot Detail display gives you slot-by-slot information about the modules and firmware in each slot as well as the runtime software operating on the slot.
Table 5 shows the slot detail display. (The example shows the detailed slot information for slot 0, the SSC module's slot.)
Table 5: Contents of the System Admin Sessions list
Field
|
Means
|
CPU
|
The governing hardware component in each slot-for example a CPU, an FPGA, and so on
|
Version
|
The version of firmware or software loaded onto each component.plus the date and time each version of firmware/software was created.
|
State
|
The state of the hardware in each slot. Valid values are:
- UP if the module is operating in runtime.
- Boot if the module is in the boot up phase.
- DOWN if the module has become inoperable and cannot progress to boot time as of the automatic reset cycle.
|
Operation
|
The operation that you can perform on the slot. This field contains a link to Filer Reboot CPU Confirmation dialog If you click the link you proceed to the dialog, where you can acknowledge or cancel a reboot of a selected slot. Figure 13 shows this dialog.

Rebooting Serval Filer Components
The Serval Filer enables you to selectively reboot either the entire module in a slot, or specific hardware/firmware components on a module.
Rebooting Modules
The reboot function for a module is located on the Filer Report display, in the
Operation field. (See
Figure 11). This field contains a link that enables you to perform a reset of the entire module. By clicking the link in the
Operation field, you invoke the Filer Reboot Slot Confirmation dialog.
Figure 12 shows this dialog.
Figure 12 Filer Reboot Slot Confirmation dialog
The slot to be rebooted is transferred from the Filer Report Chassis Configuration display. To reboot the specified slot:
· Click
Continue to reboot the slot.
· Click
Cancel to abort the reboot and return to the Filer Report Chassis Configuration display.
Rebooting Hardware Components
The reboot function for individual hardware/firmware components is located on the Filer Report Slot Detail display in the
Operation field. (See
Figure 11). This field contains a link that enables you to perform a reset of a processor on the module. As a result, the entire module might reset depending on the processor you choose to reset. By clicking the link in the
Operation field, you invoke the Filer Reboot CPU Confirmation dialog.
Figure 13 shows this dialog.
Figure 13 Filer Reboot CPU Confirmation dialog
The slot and CPU to be rebooted are transferred from the Filer Report Slot Detail display. To reboot the specified slot and CPU:
· Click
Continue to reboot the slot.
· Click
Cancel to abort the reboot and return to the Filer Report Slot Detail display.
Viewing Admin Sessions
The Serval Filer contains the Admin Sessions display. This display enables you to view the currently configured admin users and their access privileges.
Figure 14 shows the Admin Sessions display.
Figure 14 Admin Sessions List
The Admin Sessions List requires no interaction. The information displayed is gathered from the admin users that have been configured through the Serval Filer's command-line interface.
Table 6 shows the contents of the Admin Sessions List and explains what each field means.
Table 6: Contents of the System Admin Sessions list
Field
|
Means
|
User Name
|

|
Privilege
|
The access privilege-either view, add, change, or full-associated with each admin user listed in the User Name column.

Viewing the TCP and UDP Connections Lists
The Serval Filer tracks the open TCP and UDP connections on its IP interfaces. The TCP and UDP connection information is displayed on the System Switch and Controller Module as well as on the File Processing module. You can view both the TCP and UDP connection information on either module. The main difference in the information displayed is that the SSC's connections list shows the system-wide connections list whereas the FP module's connections list shows on the TCP and UDP connections supported on that module.
Viewing the TCP and UDP Connections List on the System Switch and Controller
The TCP and UDP Connection Lists can be displayed on the SSC module. This list shows the entire log of TCP and UDP connections since the last system restart. The SSC's TCP and UDP Connection Lists shows system wide information about the TCP and UDP connections established on the Serval Filer.
Figure 1 shows the TCP Connections List on the SSC.
Figure 1 TCP and UDP Connections Lists on SSC Module
The connections list contains two separate tables, one for TCP connections and one for UDP connections. The Telnet Connection Protocol (TCP) Connection List shows information about the TCP/IP connections on the Serval Filer. Table
Table 7 explains the contents of the TCP Connections Table.
