Question 9

During yesterdays business hours, a cache drive failed on one of the vSAN nodes. The administrator
reached out to the manufacturer and received a replacement drive the following day. When the drive
failed, vSAN started a resync to ensure the health of data, and all objects are showing a healthy and
compliant state. The vSAN administrator needs to replace the failed cache drive.
Which set of steps should the vSAN administrator take?

  • A. Remove the existing vSAN disk group, and physically replace the device. Then, check to verity that the ESXi host automatically detects the new device. Afterwards, manually recreate the Disk Group.
  • B. Physically replace the failed cache device, and vSAN will automatically create a new disk group. Then, remove the disk group with the failed device.
  • C. Physically replace the failed cache device, and vSAN will automatically allocate the storage. Then, rebalance the cache layer.
  • D. Place the disk group into maintenance mode, and select Full Data Migration. Then, physically replace the failed cache device. Afterwards. vSAN will rebuild the disk group automatically.
