Hi, Thank you for taking time to look into this:

i have already restarted once. Do i need to shutdown the host from vcenter and then start?

Which disk is failed ? The cache or capacity ?
Have you got an ILO/IDRAC to check the hardware ?

[jiigmey]

It's a capacity disk as shown below

Absent typically means the disk has gone missing and vSAN doesn't understand what happened to it. It wouldn't surprise me if you reboot the host that iLO also doesn't see the disk anymore. Just place the host into maintenance mode and reboot the host using iLO and then during boot check the disks to see if it is there or not.

So, I had something similar happen about a month ago on a fairly new VSAN cluster composed of a stack of Dell VSAN Ready nodes. On the IDRAC, the disk showed no errors, but did show 0 capacity. I opened a support case with Dell. In true Dell fashion, I had to upgrade the firmware for the DRAC, OS, HBA, and disks. At that point, the disk still showed 0 capacity and had an error in VSAN. The support engineer tried telling me the driver version was slightly low, but I pointed out to him this was a VCF cluster. I was trying to do an upgrade (which is a packaged upgrade), but cloud not because of a VSAN DISK ERROR. He then agreed to send me a new drive and it did resolve the issue. I say all this just to let you know it is possible to have a bad drive and not show any amber light. I do not think there was any activity light on it, but it never went amber on the server. The IDRAC still acted like all was good other than the fact it showed 0 capacity.
