A vSphere administrator is attempting to upgrade an ESXi host using vSphere Update Manager.
The administrator has attached the baseline and remediated the host. Update Manager reports the remediation process has completed successfully.
However, upon inspection the host is not upgraded.
What is the most likely reason for this issue?
A. The ESXi host has less than 10MB free in its /tmp directory.
B. The user performing the upgrade has insufficient privileges.
C. The Update Manager service has not been configured with root level access to the host.
D. The baseline has been configured using an invalid ISO image.
Correct Answer: A
Explanation/Reference:
Explanation:
This is a known issue whereby Update Manager may report that the remediation process completed successfully but no changes have been made if the ESXi host has less than 10MB free in its /tmp directory.
ESXi Host Upgrade Fails
The remediation process of an ESXi host against an upgrade baseline or a baseline group containing an upgrade baseline might fail.
Problem
An ESXi host might fail to upgrade.
Cause
When you upgrade an ESXi host with less than 10MB of free space in its /tmp directory, although Update Manager indicates that the remediation process completed successfully, the ESXi host is not upgraded.
Solution
If you see an Agent Deploy failure, make sure that the /tmp directory has at least 10MB of free space.
Repeat the remediation process to upgrade the host.
Incorrect Answers:
B: If the user had insufficient privileges, Update Manager would not run the remediation process. Therefore, this answer is incorrect.
C: If the Update Manager service has not been configured with root level access to the host, Update Manager would not run the remediation process.
Therefore, this answer is incorrect.
D: If the baseline has been configured using an invalid ISO image, Update Manager would either fail (in which case it would not report a success) or it would install the ISO. The question states that the host failed to upgrade. If it installed the ISO, the host would be modified. Therefore, this answer is incorrect.
