What to do when DSA 2800 is unable to detect the expansion unit?
System:
Dual controller 12x12TB and one expansion unit 8x12TB
Issue:
When you access the DSA via web browser by entering the IP address of the management port, you are not able to see the expansions in the Hardware tab. You only see the controller.
Also, when you add the DSA in the VRM pool, the storage capacity is less than it is supposed to.
Note Controller software 11.70.3 or later is required to recognize new E2800 hardware manufactured from October 2022 (production code 278 or later). The production code can be found in the Bosch serial number from position 8 to 10 Please check also the DSA E2800 Release Note SANtricity OS Controller Software 11.70.4R1P1 |
Please reseat (pull out and plug-in back) the SAS cables connecting both controllers and the drive extension.
Please check if there is any LED activity on the connected ports (see pages 14-16 from the below manual):

Note:
In case there are multiple expansion units or a single controller, please follow the Installation Manual (starting with page 23) to see how the connections should be done.
If you still cannot detect the expansion unit, please provide the Central Technical Support Team with the following details:
How many expansion units did you add?
