I have a poorly performing Pegasus 2 R8 unit that I am trying to troubleshoot. A colleague reconfigured it from Raid0 to Raid5 earlier this year. When I attempt to configure it back to Raid0, I am getting extremely poor performance - erratic r/w speed compared to how it was originally performing before being switched to Raid5.
Disk health appears to be all OK. In an attempt to fix, I downloaded the most recent firmware but am getting a CRC error when I try to execute the firmware upgrade. I tried to update via CLI, but hit the same CRC error. I tried different versions of the firmware - including the original 2015 firmware already on the Pegasus - but still the same error.
I have attempted this upgrade on a 2020 Intel iMac running Big Sur.
Any advice on how to bypass this CRC error would be appreciated. Thanks.
