6. In the Confirm window, confirm the settings, in Task Name type a unique name for this task

CAUTION:
•
The MP blade assigned to the LDEV that is used as a utility volume for Compatible XRC can
be changed only when the XRC session is suspended and the number of the side files of the
target session is zero.
•
Changes to the MP blade ID of an LDEV should be made during off-peak hours when the I/O
load is as low as possible. Before and after changes are made, it is recommended that the
cache write-pending rate (%) for all CLPRs is lower than 50%. Do not change the MP blade
ID when the I/O load is high -- for example: during initial copy of Business Copy Z, Continuous
Access Synchronous Z, or Continuous Access Journal Z).
•
When you change the MP blade ID of an LDEV, you should use Performance Monitor before
and after the change to check the load status of devices. Do not change several LDEV MP
blade IDs during a short period of time. As a guideline, you can change 10% or less of the
total number or the full workload of LDEV MP blade IDs assigned to the same MP blade ID at
the same time.
•
After you change the MP blade for an LDEV, wait more than 30 minutes before you try to
change the ID again for the same LDEV.
