Explanation
The system identified a change in the performance
category of an external MDisk. A storage device in the external system
might have been replaced with a device that has different performance
characteristics to the original. The ID of the MDisk is logged in
the event (Bytes 5-8 of the sense data). It might be necessary to
re-configure the tier of the MDisk so that EasyTier makes best use
of the storage.
User Response
Run the fix procedure for this event, assisting you
with the following tasks:
- Run the Detect MDisks task, so that the system
determines the current performance category of each Mdisk. When the
detection task is complete, if performance has reverted, the event
is automatically marked as fixed.
- If the event is not automatically fixed, you can change the tier
of the MDisk to the recommended tier shown in the event properties.
The recommended tier is logged in the event (Bytes 9-13 of the sense
data. A value of 10 hex indicates flash tier, a value of 20 hex indicates
enterprise tier).
- If you choose not to change the tier configuration, mark the event
as fixed.
