Procedure for Updating vSAN Default Storage Policy

1. Validation: Before applying a new policy, verify that the target VM storage policy (e.g., RAID-1, RAID-5, or RAID-6 configurations) is compatible with the underlying vSAN cluster resources, such as the number of available hosts and fault domains.

2. Navigation: In the vSphere Client, navigate to Storage and select the specific vSAN datastore.

3. Configuration Access: * Click the Configure tab.

   • Under the General section, locate the Default Storage Policy.

4. Policy Selection:

   • Click the Edit button.

   • Select the desired storage policy from the list of compatible policies (those with vSAN-specific rule sets).

   • (Optional): You may also modify the Improved Virtual Disk Home Storage Policy by clicking Edit to assign a specific policy for VM home objects.

5. Application: Click OK.
