back to article Oops. Cisco installed wrong firmware on some boxes and they report fake ‘severe faults’

Sorry to do this to you, dear reader, but here’s another item for your pre-holiday to-do list: update firmware on any Cisco DNA Center appliances you’ve acquired since September. The Register offers that advice because Cisco has issued a field notice titled “Some Cisco DNA Center Appliances Shipped Between September 2022 and …

    Do they not do testing on randomly selected samples from production line any more? Properly testing any single one of these after the "upgrade" would have showed the problem up immediately.

      "DNA Center ...does not notice these errors and continues to operate as if the RAID controller status is normal.”

        "The appliances’ management consoles therefore display a “severe fault”, plus plenty of errors indicating the SSDs have reached the end of their working lives."

      Cisco has stopped testing their own code way before 2012, otherwise, bugs like these would never have surfaced.

        Hot take: They leave the bugs there deliberately to sell support contracts.

    New firmware will be shipped in new appliances.

    Of course Cisco will be shipping new appliances with the correct firmware installed.

    WTF? You would hope these firmwares and devices would use some spec (even if proprietary) so fatal errors (even if in this case they are false) could be passed on, or there could be an error that the softwares are non-matching, or failing all that there could be a warning that the RAID card it expects to get some status from, it's getting no status at all from it. Oh well.

    That Cisco uses at least two separate software version-number systems tells me their software groups do not communicate effectively, and/or there is political infighting which overrules common sense.

    Why was I buying from Cisco again? Oh, right, I wasn't.
