Degraded disk when configuring Disk enclosure HP 2050

Dear Experts, we purchased Disk enclosure HPE 2050 yesterday to expand the storage capacity of SAN storage controller HPE MSA 2040.

We connected 1 SAS cable from OUT port of 2040 to IN port of 2050. After that, we turned on the 2050 device and add disk group, built RAID6 but it seems like take longer time than expected. Moreover, we got the "Degraded" status on Disks information, so is it normal? Can you suggest please? Should we connect the other SAS cable between 2 devices?

There are two controllers in the MSA2040. Both have to connect to the additional enclosure so out on controller 1 to one of the in ports and out from controller 2 to the other in port.

Should we create a new Volume or extend the current ones?

I would create a new one, extending takes ages.
