Important: If you update your system software to version 8.1.1 or later from a version earlier than 8.1.0, on a system where you have already installed more than 64 GB of RAM, all nodes return from the update with an error code of 841. Versions 8.1.0 and later allocate memory in a different way than previous versions, so the RAM must be "accepted" again. To resolve the error, complete the following steps:
  1. On a single node, run the svctask chnodehw command. Do not run the command on more than one node at a time.
  2. Wait for the node to restart and return without the error.
  3. Wait an additional 30 minutes for multipath drives to recover on the host.
  4. Repeat this process for each node individually until you clear the error on all nodes.
