Remove offline member EQL4210 Challenge Response Needed

Hello, I have 2 out of warranty EQL 4210 in a group, one of which appears to be catastrophic failure. Multiple failed disks, etc. It is currently showing offline and will not begin initializing. Due to the fact that this is simply a DR site it is not worth spending the time on attempting data recovery, I simply want to remove the offline member from the group and go forward with the single member.

IN order to remove the offline member it tells me I need the challenge response from Dell, and the phone support person told me an engineer would answer here. Here is the info from my member delete command:

Deleting an offline member may cause irreversible loss of data. Before the
operation can proceed, contact Dell Customer Support to ensure that this is
an appropriate action. If Dell Customer Support believes that this is the
correct path, they will provide a response to match the following
firmware version and challenge number.

To cancel this operation, press without entering a response.

Firmware version: V9.0.5
Challenge: 2560
