Array reconfiguration precautions include the following:
• If the LUN presentation from the array to the MPX200 is changed, click the Refresh button two or three times to see
the changes.
• Wait for a few seconds between retries because the MPX200 will be running the discovery process.
Remove unused arrays for the following reasons:
• DMS allows a maximum of seven arrays to be configured at any time.
• Arrays stored in persistence consume resources even if the array is offline and no longer needed.
• After the migration is complete, HP recommends that you remove the arrays.
• If the array-based license was used and the array will not be used in the next project, remove the license for this
array.
Array-based license use requires the following precautions:
• If you reconfigure a removed array, it may require a new array-based license.
• Use a maximum of 32 array-based licenses at any time.
• Use an array-based license if you require an ongoing replications of LUNs for the array.
