How will the following command change the datalv logical volume? chlv --e m datalv

The -e flag sets the inter-disk allocation policy, not encryption; encryption on AIX logical volumes uses a different mechanism entirely.

Spreading across the maximum number of physical volumes corresponds to the 'x' (maximum) policy, not 'm' (minimum), and chlv does not immediately rebalance existing partitions.

In AIX, the chlv -e flag controls the inter-disk allocation policy for a logical volume. The value 'm' specifies the minimum policy, which concentrates logical partition allocation onto as few physical volumes as possible. This policy applies to future allocations; it does not immediately reorganize existing partitions.

While 'minimum number of physical volumes' is technically correct for 'm', the word 'immediately' is incorrect because chlv -e only sets the policy for future allocations and does not rebalance existing logical partitions.
