8 Restrictions
This chapter details the restrictions that apply to DMS for reconfiguring LUNs on a
storage array and provides the steps for removing an array after completing data
migration jobs.
Reconfiguring LUNs on a Storage Array
Carefully handle reconfiguration of a LUN ID following these guidelines:
 Do not change the LUN ID for any LUN that is currently assigned to a data
migration Job.
 If a data migration job is completed or stopped on a specified LUN, you must
acknowledge or remove the migration job before reassigning the LUN ID.
 After changing the LUN presentation from the array to the MPX200, where a
different LUN is presented to the same LUN ID, click Refresh three times in
the HP StorageWorks mpx Manager GUI and verify that the state of the LUN
is online. Also, make sure that the correct LUN world wide unique LUN
name (WWULN) and path information are shown.
Removing an Array After Completing Data
Migration Jobs
After you complete all data migration jobs, remove the storage array following
these steps.
To remove an array after completing data migration jobs:
1. Acknowledge or remove all data migration jobs associated with the array
being removed.
2. Remove the configured zones containing MPX200 Fibre Channel ports and
controller ports of the array.
3. Wait for up to 30 seconds to see the array in the offline state in the show
array output (see “show array” on page 5-36).
