DAE 0 1 SAS cables are not connected correctly.

Hello nhannt67,

Which type of DAE are you adding 15drive, 2.5 inch disk drive, 80 disk DAE, etc. When adding the Dae did you use the guides for adding a DAE? If not here is a link to the Unity info hub and if you look under the Add and Replace Unity hardware it has the guides listed for adding DAE. https://www.dell.com/support/kbdoc/en-us/000126652/dell-emc-unity-info-hub-product-documents-and-information

Reboot sequentially for each storage processor.
The problem will be resolved once the cables are connected properly.
