Thanks Rajesh!! Glad to know that you liked our vSAN lectures. We try uploading more lectures soon. Keep Sharing and Enjoy Learning VMware with GOVMLAB!!
Your videos are really very helpful..i really appreciate your efforts. I have a request that if possible so please make any video regarding vsan introduction, how it works, benifits, limitations, etc deep drive. Thank You!
Thanks @ahmed for appreciating our hard work in creating these videos and more importantly, you liked our video. Keep Inspiring us to create more such videos by providing your valuable feedback and comments!!
Unhealthy disk status in vsan: "I have 6 hosts in my vCenter that have their disks participating in vSAN. Due to some disks testing, I had to remove one of the disks from vSAN several times and replace it with a new one. Ultimately, this caused an "unhealthy" error to appear in the disk management section of vCenter, with a red icon next to the disk. Now, the entire disk group is in an "unhealthy" state, and that disk group is in out of service. Is there a hardware issue with this disk, or is there a firmware problem on disk? I doubt it's a hardware issue since we purchased this disk recently. If you have any solutions, I would appreciate your guidance. Thank you.
Dear Learner, The unhealthy disk status in your vSAN environment could result from multiple factors, and it's not necessarily a hardware failure. 1. Check Disk Hardware Status: Go to vCenter and check the Hardware Status tab of the host where the disk is attached. Look for any critical or warning statuses that could indicate a hardware issue with the disk. 2. Validate Disk Firmware Compatibility: Check if the firmware of the newly replaced disk matches the recommended version for your vSAN hardware. You can compare the firmware version against the VMware Hardware Compatibility Guide (HCL). 3. Check Disk Group Health: Since the disk group is showing "unhealthy" and is out of service, check the logs in vSAN Health Service: vSAN Health Service → Disk Health. Look for any errors or warnings related to the disk or disk group. 4. Rebuild or Resync Disk Group: Sometimes, vSAN marks a disk group as unhealthy if it is out of sync with the rest of the cluster. Try resynchronizing the objects in that disk group: Go to vSAN → Monitor → Resyncing Components. 5. Review vSAN Logs: For a deeper investigation, review vSAN logs /var/log/vmkernel.log or vsantraced.log to see if any disk-related errors are listed
Hi You can configure vSAN services on existing cluster without powering off vCenter Server. If you already have cluster created then vSAN services can be configured without putting host into maintenance mode.
Thanks for your kind appreciation. Glad that you liked our lectures and found it useful for learning VMware. Keep Sharing and Enjoy Learning VMware with GOVMLAB!!
can you do a video on Deployment of vCenter & vSAN at the same time on those 3-host (with no iSCSI or NFS or Local Datastore), the only Datastore it will have is the vSAN ????
Hi Sorry but we didn't understand your request very well. vCenter Deployment and vSAN deployment are two different things. You can check out our lectures on vCenter Deployment as well. It might clarify your doubts!!
@@govmlab ruclips.net/video/VOdbVi3tTrU/видео.html similar, but that video can't be consider as real lab deployment, because the external switch config is not done inside each esxi host, he uses 4 external switch, with each esxi connecting 2 port to each switch.
@Frempong Glad to hear that you liked our tutorials and finding it useful to learn VMware. There are 3 ways to configure VLAN in vSphere Environment. 1. EST ( External Switch Tagging) 2. VST ( Virtual Switch Tagging) 3. VGT ( Virtual Guest Tagging) It would be difficult for me to go deeper in each of this method over chat. But just to clarify your doubt, VST is the most popular mechanism to configure VLAN. To isolate the traffic in vSphere Environment using VST, you will have to configure VLAN ID at each portgroup level. For ex. create a PG for vMotion Traffic with VLAN 101, create another PG for iSCSI Traffic with VLAN 102. That's how we isolate the traffic from each other in vSphere Environment by configuring VLAN ID at each port group level. I hope it clarifies your doubt!!

Sure Kuldeep.
We will try our best to create more videos on vSAN as you requested.

Good work bro.. , can u do some troubleshooting scenarios
Sure. We will create it soon
How do you create a vSAN cluster, if one of your esxi's hosts is hosting vcsa? It wont be able to go into maintenance mode
Hi
You can configure vSAN services on existing cluster without powering off vCenter Server.
If you already have cluster created then vSAN services can be configured without putting host into maintenance mode.

Hi I am enjoying your tutorials and new to your channel. Do you have any tutorials on how to setup vlan on esxi to separate traffics?
