If you have worked with VxRail as long as I have then you know it is inevitable to relocate a host from one cluster to another to support other projects. Also, it is likely you’ve had a couple hosts laying around in the datacenter awaiting install. I thought I would put together this quick how to configure the VxRail host to be discovered via VxRail Manager and add the host via vCenter.
If you would like assistance in the below or have general questions about Cloud solutions, VMware, and more, feel free to visit the following URL and I will be able to work directly with you:
In case you need to also know how to remove a host from a cluster please see my other blog article:
The How To Process
First log into the iDRAC and Power on System if it isn’t already
Launch Virtual Console
Be patient and wait for boot
F2 to configure
First go to Configure Mangement Network
Confirmed Disable IPv4 configuration for management network
Now select VLAN (optional)
Enter the VLAN for your ESXi Management Network
Click <Esc> to Exit
Click <Y> Yes
You should see now the host has a IPv4 IP randomly generated
Scroll down to Troubleshooting Options and enter
Enable ESXi Shell and Enable SSH then Esx to exit
Return to the main screen and Alt-F1 to open a virtual console window to the host
Log in as Root
Enter the date command to get the current date & time of the host and compare it against the VxRail Manager date & time to confirm they are close in time.
****If not then please see my blog on changing the time on a ESXI host
Double check the Management VLAN that your other VxRail Hosts are located on.
#esxcli network vswitch standard portgroup list
#esxcli network vswitch standard portgroup set -p “Management Network” -v <Your_VLAN_ID>
#esxcli network vswitch standard portgroup set -p “VM Network” -v <Your_VLAN_ID>
Finally, log into vCenter and go to Host & Clusters > Cluster > Configure > VxRail > Add VxRail Hosts > ADD HOST
**be patient – can take up to 5 minutes for VxRail Manager to discover the new host
Click Add host
Select the host you want to add.
Now enter your username/password
Next you will need to put the next IP in your original reserved pool for ESXi Management, vMotion, and vSAN.
Next comes entering your different credentials for your environment.
You can choose whether or not to put host in maintenance mode
The good old summary and validate page.
As you can see there are a lot of working parts here but it is well worth it. I hope I made this easy to follow. As always, I hope y’all found this helpful.
