Which of the following commands should the administrator execute to resolve the issue?
Correct Answer: A
The error message indicates that the logical volume is inactive. To activate the volume group, vgchange -ay data is required.
Option A (Correct): This command activates all logical volumes in the volume group data.
Option B: Scans logical volumes but does not activate them.
Option C: vgimport is used for importing volume groups from another system, which is not the issue here.
Option D: lvchange -ay is used for activating specific logical volumes, but the volume group must be activated first.
