Changing the MP blade assigned to an LDEV
CAUTION:
•
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, Continuous
Access Synchronous, High Availability or Continuous Access Journal).
•
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.
The Storage Administrator (System Resource Management) role is required to perform this task.
