vSAN not showing all available disks when attempting to claim

[BiswarajPattan]

Hi All,

I have setup my LAB environment in VMware workstation 16. where i have configured three ESXi nodes VMware esxi 6.7. I have installed vcsa6.7 appliance..

Node1- disk1 =40GB and disk 2= 10 GB

Node2 disk 1 =40 GB and disk2 =10 GB

Node3 disk1 =40 GB and disk2 =10 GB.

I am attempting to setup new vSAN cluster but noticed that the wizard not showing any disks. Please find the attached image for your reference. Requesting your solutions further troubleshooting.

@BiswarajPattan, Do the devices have partitions on them? If they do then they will not show as eligible for claim for use by vSAN.

This is easily checked via vSphere client: Host > Configure > Storage devices > Select device > Partition details.

Hi

Thanks for the solutions. I have deleted all the virtual HDD and trying to recreate the vSAN cluster again. Please find the attached screenshot for your reference. Now i am going to configure the  vSAN cluster using Quick start method. There are three sections

1. Cluster Basics --- Done

2.Add Nodes --- Done

3. Configure cluster-  Greyed out.

Please suggest........... How to configure.

Try the "manual" setup of a vSAN and not the quickstart wizzard.

@BiswarajPattan  what is that 1 red alert in the QS pre-requisites that we can see just the edge corner of in the screenshot?

This is a small cluster, I would advise just configuring this manually without QS as @IRIX201110141  advised.

[BiswarajPattan]

Thank you for your advise Bobkin. The Red alert is "Physical disk health retrieval issues"

Sure I will try manual process and let you know.

I have tried to configure using manual process but options are greyed out. Its not allowing me to select the disk to claim.

Remove existing partitions from that drives again or create new ones within your virutal environment.

@BiswarajPattan Is this a nested lab or real physical disks? If the former then possibly disk/disk-groups are unmounted due to PLOG OOM, seen it a few times when running nested ESXi with minimal memory allocated to the ESXi VMs.

Please check if existing disks haven't been part of VSAN cluster before, if they have been then you need to erase and re-partition them. check the disks which shows partition detail with as vSAN Metadata erase those disks. Once done rescan the storage device against the cluster and reattempt configuring the VSAN.
