Environment

VMware Cloud Foundation 5.x

Cause

The SDDC Manager identifies disks that are eligible for use by vSAN and utilizes those disks to create disk groups.

However, in some cases, issues may occur even if the OS disk is not marked as eligible for use by vSAN.

 

Resolution

Follow the below steps :

• Take the snapshot of the SDDC manager.

ssh to SDDC as vcf, su to root

• Add this property to the file /etc/vmware/vcf/domainmanager/application.properties

validation.disable.vsan.disks.check=true

• Restart domain manager service

systemctl restart domainmanager

• Restart the task.

 

 

After the ESX host is added successfully remove this line again from /etc/vmware/vcf/domainmanager/application.properties

validation.disable.vsan.disks.check=true

• Restart domain manager service  

systemctl restart domainmanager
