1. DC power harness
The Storage Manager client
Enterprise Management
window sees each storage
server controller as an
independent storage
subsystem.
No drives are present in the storage server.
Ensure that at
least one drive is present in the storage server so that it can
be configured properly.
One controller was replaced incorrectly. The controller
firmware versions probably failed to synchronize correctly.
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 Storage Manager client Enterprise Management
window still shows each storage server controller as an
independent storage subsystem or a partially managed
device, repeat this procedure. If the problem still persists,
contact IBM support.
