This video shows how to replace the System Memory on a VxRail appliance.
Before you begin, ensure that your virtual machines are migrated to another host.
If your Clusters are running on Standard License,
manually migrate the virtual machines to another host.
For manual migration, login to vSphere Client,
click the hamburger menu on the top-left corner of the page and select Inventory.
Expand the vCenter Server,
the VxRail Datacenter
and the VxRail Virtual SAN Cluster
and locate the ESXi host that is running on the faulty node.
Verify if there are virtual machines running on the ESXi host.
Select the faulty host in the left pane.
In the right pane of the page, click the VMs tab and then the Virtual Machines tab.
Right click the virtual machine that is running and select Migrate.
While selecting the migration type, select Change
both compute resource and storage and click NEXT.
Select a compute resource as the target host and click NEXT.
Select a destination storage for the virtual machine migration and click NEXT.
Select a destination network and click NEXT.
Select the applicable vMotion priority and click NEXT.
Click FINISH.
Ensure that all virtual machines have been
migrated before powering off the faulty node.
Put the faulty node in maintenance mode.
Select the VxRail virtual SAN cluster from the left pane.
In the right pane, select the Hosts tab
and right click on the node that you have to shutdown
and click Maintenance Mode,
and then select Enter Maintenance mode.
Click OK and acknowledge the warning.
Before shutting down the faulty node, ensure that
the cluster’s health monitoring is set to enable.
To enable the health monitoring, select the VxRail Virtual SAN Cluster,
click the Configure tab and scroll down the pane.
Under VxRail, select Health Monitoring.
In the right pane, under the VxRail Cluster Health Monitoring
ensure that the status is Enabled.
If it is disabled, select the slide button to enable it.
Shutdown the faulty node from the vCenter server.
Select the VxRail Virtual SAN cluster, click the Monitor tab
and scroll down the pane.
Under VxRail, select Physical View.
From the right pane, select the faulty node and click ACTIONS.
From the list, select Shutdown Host.
Select VM Migration and click NEXT.
Confirm validation was successful and click NEXT.
Confirm shutdown and click NEXT.
Monitor the shutdown process.
Once host shutdown has completed, click FINISH.
Power off the appliance and disconnect all the attached peripherals.
Ensure that you always use ESD protection when working inside the appliance.
To replace the system memory, first remove the system cover.
To do this, if the latched lock is in the locked position,
rotate it to the unlocked position.
Lift the latch to disengage the cover from the system.
Then lift the system cover off.
Lift the air shroud from the system and remove it.
Locate the appropriate memory module socket.
simultaneously press the ejectors at both the ends of the memory module socket
To replace the system memory,
Align the edge connector of the new memory module
with the alignment key of the memory module socket
and insert the memory module in the socket.
Place the air shroud back in position inside the system.
Finally, install the system cover by placing
the system cover into its position on the system
Lower the latch to engage the cover onto the system.
Then rotate the lock on the top of the system cover to the locked position.
Reconnect all the cables and power up the node.
Once the system memory is replaced, exit the maintenance mode.
To exit the maintenance mode,
select the VxRail virtual SAN cluster from the left pane.
In the right pane select the Hosts tab
and right click on the node that was previously shutdown
and click Maintenance Mode,
and then select Exit Maintenance mode.
Enable the Cluster Health Monitoring if it is disabled.
To enable the health monitoring, select the VxRail Virtual SAN Cluster,
click the Configure tab and scroll down the pane.
Under VxRail, select Health Monitoring.
In the right pane, under the VxRail Cluster Health
Monitoring ensure that the status is Enabled.
If it is disabled, select the slide button to enable it.
Lastly, migrate the virtual machines back to the node.
To do this, refer to the previous section of this video
where we explain the step by step instructions
for migrating the virtual machines.
