This part of the lab is presented as a Hands-on Labs Interactive Simulation. This will allow you to experience steps which are too time-consuming or resource intensive to do live in the lab environment. In this simulation, you can use the software interface as if you are interacting with a live environment.
It is important to note that VxRail is powered by vSAN and has built-in data protection. Depending on the specific configuration of vSAN different drive failure conditions are handled differently. Monitoring the health of a disk drive is key to ensure data protection. VxRail and vSAN both have methods to detect and report disk drive health.
VxRail Manager is also used to replace failed disk drives without disrupting availability, to generate and download diagnostic log bundles, and to apply VMware updates or software patches non-disruptively across VxRail nodes.
The vSphere Web client is available to manage the VxRail appliance, However, VxRail also provides VxRail Manager to assist with the lifecycle management of VxRail. An administrator would need to replace a device currently in use for a VxRail Applliance if a device error has been detected.
For this lab the we are using the following VxRail archtecture:
Storage capacity for the VxRail Appliance is provided by disk drives that have been integrated, tested, and validated by Dell EMC. 2.5” form-factor Solid State Disks (SSD) and mechanical Hard Disk Drives (HDD) are used. A configuration the uses 3.5” form-factor drives is also available for dense storage requirements. Disks drives are logically organized into disk groups.
Disk groups are configured in two ways:
A higher-endurance SSD is used for write caching and capacity optimized SSDs are used for the capacity tier. Currently, the caching tier uses 200GB, 400GB, 800GB, and 1600GB flash disks, and the capacity tier uses either 1.92 or 3.84TB flash SSDs, 1.2TB HDDs, 2TB HDDs, and 4TB (3.5” form-factor). All VxRail disk configurations use a carefully designed cache-to-capacity ratio to ensure consistent performance.
The orange boxes show where to click, and the left and right arrow keys can also be used to move through the simulation in either direction.
In the vSphere Web client you can see the health of the vSAN cluster devices. It shows the system is operation in a Healty state. This currently shows no errors are detected.
If any device is displaying an error, work with your Dell EMC support staff to confirm error any necessary logistics required to have the hardware on hand replaced.
The following demonstrates how to use the VxRail Manager UI to prepare the node for the removal of a SSD Device. You can view the Disk Groups under Disk Management in the vSphere Web Client and in the Health Dashboard under Capacity for the ESXi Nodes.
Within the VxRail Manager application, the right pane is focused on the "Health" of the VxRail appliance. Click the word Physical to change the view of the VxRail to show physical health details.
The physical disk is now ready to be replaced. The physical details of the appliance are shown on screen. You can confirm the physical details on screen: which VxRail Appliance, which ESXi node, which slot and disk serial number.
When the work has been completed, you can Click Continue to finish the disk replacement procedure.
This completes the whole process to Troubleshoot and replace a VxRail Hard Disk failure. We demonstrated the ease of replacement within the UI with just a few navigational clicks.
Please proceed to the conclusion of Module 3.
