First Claim
Patent Images
1. A method of propagating firmware updates in a RAID array, the method comprising:
- identifying, by a RAID controller, that a first drive has a firmware that is uplevel with respect to firmware of at least one other drive, the RAID controller comprising a module of automated computing machinery;
selecting, by the RAID controller, a second drive having downlevel firmware with respect to the firmware of the first drive;
obtaining, by the RAID controller, an uplevel firmware image from the first drive; and
updating, by the RAID controller, the downlevel firmware on the selected second drive with the obtained firmware image.
