I have a degraded RAID 5 array with one bad drive I am replacing. I have not updated the firmware or updated the utility since the purchase 6 years ago. I am currently running Catalina and if I download the lastest utility to rebuild the array, I am assuming the utlity will prompt to update the firmware.
I hesitate to update the firmware with a degraded array, but I wanted to check in with a more knowlable person to make a suggestion.
Please Advise,
Mark
