QuestionQ34

Installing, Configuring, and Setup

A vSAN administrator manages an existing cluster in which every ESXi host contains the following:

  • Disk group #1: one cache device and three capacity devices.
  • Disk group #2: one cache device and two capacity devices.

What must the vSAN administrator do to expand disk group #2 so that it has three capacity devices?

  • A Create a new disk group with a single capacity device and then migrate the existing capacity devices
  • B Add the new capacity device to the disk group and vSAN will automatically rebalance
  • C Put the entire ESXi host in maintenance mode, evacuate all data, then add the new capacity device
  • D Put the disk group in maintenance mode, evacuate all data, then add the new capacity device
Explanation

An existing vSAN disk group can accept an additional capacity device while remaining online. After the capacity device is added, vSAN automatically rebalances data to use the new storage capacity; maintenance mode and data evacuation are not required.
