Good afternoon,   I'd be looking at an issue with the backplane or cabling, but potentially the connector on the controller. I'd recommend reseating the backplane cables to see if that corrects the behavior. If not, then exporting a controller log from the PERC to see what sense keys are being generated would be the next thing I would look at. Linked below is an article on exporting the controller log using OpenManage Server Administrator. Let me know if you have any questions. [URL]
Hello I got a poweredge t320 with 8 bays for disks. Bay 0-5 works but 6 and 7 isn't. Orange light is blinking. When i move the disk to another bay it starts and works. I updated the firmware on my raid controller, but its the same.   Any ideas? Best regards
T320 Disk 6 and 7 failure
