A vSAN administrator has a cluster configured with a Storage Pool that was moved to a new physical DC.
Upon checking on the vSAN cluster health status, one of the ESXi hosts has two storage devices in a degraded state and must be replaced.
What must the vSAN administrator do to restore the health of the vSAN cluster with minimum risk?
To restore the health of the vSAN cluster with minimum risk, the vSAN administrator must remove the devices from the storage pool, replace the storage devices, and then claim the new devices in vSAN. This approach ensures that only the affected storage devices are removed and replaced without disrupting the entire storage pool or the cluster configuration. This minimizes the risk and keeps the cluster operational during the process.

remove disk -> add disk -> add storage pool
C. Remove the host from the cluster, replace the faulty disks, re-add the host to the cluster. Here's why this is the recommended approach: Removing the host from the cluster: This isolates the problematic host, ensuring that it doesn't contribute to any further issues or data corruption in the cluster. Replacing the faulty disks: After removing the host, replace the degraded or faulty storage devices to ensure that you have healthy, functioning hardware. Re-adding the host to the cluster: Once the disks are replaced and the host is back online, you can re-add it to the vSAN cluster. This allows the cluster to rebuild and resynchronize the data across the new devices and restore redundancy. This approach minimizes the risk of data loss or corruption and ensures that you have a healthy vSAN cluster with the least disruption.

On the Configure tab, click Disk Management under vSAN. Select the storage pool device, and click Remove Disk. In the Remove Disk dialog box, select Full data migration to transfer all the data available on the host to other hosts in the cluster. Click Go To Pre-Check to find the impact on the cluster if the object is removed or placed in maintenance mode. Click Remove to remove the storage pool device. What to do next Add a new device to the host. The host automatically detects the device. If the host is unable to detect the device, perform a device rescan. Claim a disk using the vSAN cluster > Configure > vSAN > Disk Management.
