NetApp Certified Implementation Engineer – SAN, Specialist — Question 52

An administrator has presented a thinly provisioned iSCSI LUN to your ESXi host. The administrator deleted data from the datastore in ESXi. No blocks have been freed on the LUN.
What are two of the steps the administrator should use to solve this problem? (Choose two.)

Answer options

• A. Use the vmfs unmap command
• B. Rescan the storage from the host
• C. Set the volume to thin-provisioned
• D. Set the space-allocation to enabled\

Correct answer: A, D

Explanation

The correct steps to resolve the issue are A and D. The vmfs unmap command is specifically designed to reclaim unused blocks in a thin-provisioned LUN, and enabling space-allocation allows the system to manage block reclamation effectively. Options B and C do not directly address the issue of block reclamation on the LUN.
