Hardware Page
The Hardware page displays information about the hardware components of a ztC Endurance system. The top pane lists the state, activity type, name, and serial number of each compute module, I/O module, storage module, and PSU in the system. The bottom pane displays detailed information about the top-pane component that is currently selected.
When you select tabs in the bottom pane, the information displayed is generally self-explanatory. However, additional information about the Memory, Network, Fibre Channel, and Storage tabs is provided later in this section.
In addition to viewing information about hardware components, you can use the Hardware page to do the following:
-
Identify a hardware component by clicking a button to flash its ID LED (see Identifying a System or Component).
-
Place a compute module into maintenance mode
A ztC Endurance compute module state that suspends module operation so that it can be serviced. When an active compute module enters maintenance mode, the system performs a Smart Exchange, then activates the standby compute module. Compute modules must be in maintenance mode before they are shut down., shut it down, and then return it to service (see Using Maintenance Mode ). -
Go to the BMC login page. From the compute module's BMC tab, click an IP address to go to the BMC login page (see Logging In to the BMC Web Console).
Hardware States
The State values show the severity of the component's state. Values are:
-
Informational (
): Hardware slot not actively involved in the system. -
Normal, in sync, or OK state (
): Operating normally. -
Minor, warning, or inconsistent state (
): User attention recommended. -
Moderate state (
): Module is simplex; user attention required. -
Broken, failed, or severe state (
): Component not operational; user attention required. Activity text may provide additional information about this state.
-
Syncing (
): Component is working to become redundant again or the compute module is performing a Smart Exchange A proprietary process that maintains system availability and protects against data loss. If the ztC Endurance system detects a degradation or failure within the active compute module, Smart Exchange:
1) Automatically activates the standby compute module and copies over in-process data.
2) Reroutes all I/O and storage connected to the original active compute module to the newly activated compute module.
Smart Exchange occurs while the system is running and, except for a very brief pause (usually less than one second), is undetectable to the operating system and customer applications.. -
Maintenance mode (
): Component is in maintenance mode. See Using Maintenance Mode.
Hardware Activity Types
The Activity values show the component's current activity type. Values are:
-
Running (
): Component provides an operating environment and is running normally. This value applies only to the active or standby compute module. -
Connected (
): Component is actively connected to the active compute module and is operating normally. This value applies to storage modules, I/O modules, and PSUs. -
Shutting Down (
): Compute module is shutting down. See Shutting Down and Restarting a Compute Module. -
Shutdown (
): Compute module has shut down. -
Smart Exchange (
): Active compute module is performing a Smart Exchange to the other compute module. -
Recovering (
): Compute module is transitioning. -
Booting (
): Compute module is booting. -
Failed (
): Component has failed and is not operational. -
Disconnected (
): Component is not connected to the active compute module. -
Off (
): Component is powered off.
To learn more about the Memory tab
On the Hardware page, you can learn more about a specific compute module's memory by selecting the compute module and then clicking its Memory tab in the lower pane. The Memory columns have the following meanings:
-
State: Displays the state of the RDIMM. For example, a green checkmark in the State column indicates that the RDIMM's state is good. See Hardware States for more information about the hardware states and their associated icons.
-
Name: Displays the name of the RDIMM (for example, DIMM8).
-
Slot: Displays which of the two RDIMM slots on a channel an RDIMM is physically plugged in to. Because ztC Endurance systems implement only one slot per channel, you can ignore the values in this column.
-
Socket: Displays the processor to which an RDIMM is connected. For example, a value of 1 indicates that the RDIMM is connected to processor 1.
-
Channel: Indicates the number of the channel (that is, a physical set of wires) between the processor and the RDIMMs. Each processor in a ztC Endurance system has 8 RDIMM channels.
-
Capacity: Displays the size of the RDIMM, in gigabytes (for example, 32 GB).
See Memory in ztC Endurance Systems for more information about RDIMMs.
To learn more about the Network tab
On the Hardware page, you can learn more about a system's Ethernet PCIe adapters.
-
To learn about a specific compute module's embedded Ethernet PCIe adapters, select the compute module and then click its Network tab in the lower pane.
-
To learn about a specific I/O module's Ethernet PCIe adapters, select the I/O module and then click its Network tab in the lower pane.
The Network columns have the following meanings:
-
State: Displays the state of the component. For example, a green checkmark in the State column indicates that the PCIe adapter's state is good. See Hardware States for more information about the hardware states and their associated icons.
-
Location: Displays the location of the component. For example, in a compute module, embedded-A means that the embedded PCIe adapter is located in PCIe slot A. In an I/O module, slot B/2) means that the PCIe adapter is located in I/O module B, slot 2.
-
Name: Displays the name of the component (for example, vmnic0).
-
Port: Displays which port the component is connected to (for example, 1).
-
PCI ID: Indicates the component's PCIe address identifier on the system (for example, 0000:9e:00.1).
-
Speed: Indicates the speed of the component (for example, 10 Gbps).
-
MAC Address: Displays the component's burned-in MAC address (for example, 34:a6:61:fb:18.94), not its virtual MAC address.
To learn more about the Storage tab
On the Hardware page, you can learn more about a specific storage module's disks by selecting the storage module and then clicking its Storage tab in the lower pane. The Storage columns have the following meanings:
-
State: Displays the state of the disk. For example, a green checkmark in the State column indicates that the disk's state is good. See Hardware States for more information about the hardware states and their associated icons.
-
Location: Displays the location of the disk. For example, slot A/6 indicates that the disk is located in storage module A, slot 6.
-
Name: Displays the name of the disk (for example, vmhba64:C0:T0:L0). If the disk slot is empty, Empty is displayed.
-
PCI ID: Indicates the disk's PCIe address identifier on the system (for example, 0001:74:00.0).
-
Availability: Indicates if the disk is redundant (that is, paired with another physical disk). If the disk slot is empty, Unused is displayed.
-
Logical ID: Displays the logical ID of the disk (for example, mpm1). If the disk slot is empty, Unconfigured is displayed.
