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.
In addition to viewing information about hardware components, you can use the Hardware page to do the following:
-
Identify a hardware component (see Identifying a System or Component).
-
Enter 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.
Note that placing a ztC Endurance compute module into maintenance mode is unrelated to placing an ESXi host into maintenance mode., 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 alert severity. 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 (
): User attention required. -
Broken, failed, or severe state (
): Component not operational; user attention required.
-
Running (
): Component is running normally. -
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:
• Automatically activates the standby compute module and copies over in-process data
• 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.
