The DS4000
Storage Manager
client Enterprise
Management
window sees
each storage
subsystem
controller as an
independent
storage
subsystem or a
partially
managed device.
Controller If this condition occurs after
you have replaced a
controller, the controller
firmware for the replacement
controller probably failed to
synchronize with the
firmware on the existing
controller.
To recover, perform the following steps:
1. Remove and reinsert the controller blade.
2. Wait 5 minutes.
3. Delete the controller entry with the incorrect
firmware version from the DS4000 Storage
Manager Enterprise Management window.
4. Add the controller back to the DS4000 Storage
Manager Enterprise Management window
using the Add Device menu option in the
Enterprise Management window.
5. If the DS4000 Storage Manager client
Enterprise Management window still shows
each storage subsystem controller as an
independent storage subsystem or a partially
managed device, contact IBM support for
instructions on how to force firmware
synchronization in the replacement controller.
The DS4800 has been
powered on without a
connection to at least one
storage expansion enclosure
populated with at least two
drives.
If this is the case, power off the DS4800 and
connect at least one storage expansion enclosure
populated with at least two drives.
The attached storage
expansion enclosures and/or
drives in the attached
storage expansion
enclosures are not certified
or not supported by the
DS4800.
The DS4800 will not recognize non-IBM storage
expansion enclosures and drive models. If you are
positive that storage expansion enclosures and
drives are of IBM models, obtain the DS4800
Subsystem Profile and call IBM support.
Random errors Subsystem Mid-plane has failed Contact IBM Support.
Note: If you cannot find the problem in the Symptom-to-FRU index, test the entire
system.
