We have a disk shelf DS4243 with 23 7200 RPM disk. We are receiving multiple errors related to power supply. We have installed 2 PSUs in the disk shelf. The error is :- Not enough power supplies are present in channel XX disk shelf XX to satisfy disk drive and shelf power requirements.
I am unable to find any document or recommendation from NetApp related to the number of PSUs required to support 23 disk of 7200 RPM in a shelf.
