Hello,

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.

Hi Ben,

You may have a drive issue, it's not possible to tell.

Regarding the firmware update issue please update to the latest Pegasus32 Promise Utility, it is backwards compatible with the Pegasus 2. This may help.

Hi - 

I was able to flash the firmware using a different Mac. I did not try the updated Utility on the first Mac, but it probably would have solved my problem. 

Thanks

Hi Ben,

Just an FYI. After investigation it turns out that there is an issue with the latest Pegasus32 Promise Utility (4.06.0000.04) and it will give a CRC error when attemptin to update firmware on the Pegasus2. This will be fixed next Promise Utility release, but the workaround is to use an earlier version of the Promise Utility. Version 4.06.0000.01 has been tested and works when updating firmware on a Pegasus2.
