| Seeking Help | Replacing Failed Disk Offline'd FileSystem

Good Morning Dell EMC DD Community,

I hope we are all starting our week after a terrific weekend! I am reaching out to see some assistance in diagnosing what occurred on our DD2500 when replacement of a failed disk drive brought the entire filesystem offline. My colleague completed replacement between 9:30AM-10:30AM on Thursday 5/30. Shortly after the disk entered the system the state of the filesystem changed to " **** The filesystem is not responding.", the array was no longer ping-able on the network and I believe the disk state turned to Absent or remained reading as failed. I have linked the SUB from the array from my DB below. Any and all help is GREATLY appreciated as this array is no longer under Dell EMC Support. I thank you for your time, consideration and work!
