VCP-DCV Configure and Manage vSphere Storage Practice Question
Exhibit
status = 'fail' msg = 'Failed to enable vSAN on host 192.168.1.100: vSAN requires at least one disk group with a capacity tier.' host = '192.168.1.100'
Refer to the exhibit. An administrator tries to enable vSAN on a host and receives this error. What is the most likely cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The host has disks but they are not claimed for vSAN or not configured in a disk group.
vSAN requires at least one disk group consisting of one or more capacity disks (and optionally a cache disk). The error indicates that no disk group is present or the disks are not properly claimed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The vSAN cluster has insufficient hosts (needs at least 2).
Why it's wrong here
A vSAN cluster can be enabled on a single host for evaluation, and the minimum host count applies to cluster configuration rather than the enablement operation itself. It is tempting because two hosts is the documented minimum for a supported cluster, but the error shown concerns host-level storage, not cluster membership.
- ✗
The host does not have any disks installed.
Why it's wrong here
vSAN requires at least one local disk per host to contribute storage, and the enablement error specifically flags missing capacity devices. It is tempting because a diskless host genuinely cannot join a vSAN cluster, but the exhibit error points to a different prerequisite, so this is not the stated cause.
- ✓
The host has disks but they are not claimed for vSAN or not configured in a disk group.
Why this is correct
vSAN requires local disks to be claimed and assigned to a disk group before it can be enabled. Unclaimed or ungrouped disks leave no storage capacity for the vSAN datastore, so the enable operation fails until the administrator creates a disk group.
- ✗
The host's disks are all SSD and vSAN requires HDD for capacity tier.
Why it's wrong here
vSAN supports all-flash configurations, using SSDs for both cache and capacity tiers, so an all-SSD host is valid. It is tempting because vSAN historically required a cache tier distinct from capacity, but the exhibit error relates to device availability, not disk media type.
