EMC Proven Professional – Symmetrix Solutions Specialist — Question 16

What is a recommendation when using Open Replicator to migrate data from a supported third-party array to a VMAX3 array?

Answer options

• A. Host I/O to the control devices on the VMAX3 array is allowed after the migration completes
• B. Host I/O to the remote devices on the third-party array can continue during the migration
• C. Control devices on the VMAX3 array must be set to Not Ready for the duration of the migration
• D. Host I/O to the remote devices on the third-party array should be stopped for the duration of the migration

Correct answer: C

Explanation

The correct option is C because control devices must be set to Not Ready to ensure that no I/O operations interfere with the migration process. Options A and B are incorrect as they suggest that I/O can continue, which could lead to data inconsistencies. Option D is misleading since it implies stopping I/O on the third-party array, but the focus should be on the VMAX3 control devices.
