text: Figure 13-24 Updating system level 
  
  The update process completes when all nodes and the system unit are committed. The 
  final status indicates the new level of code installed in the system. 
  
  **Note:**If your nodes have more than 64 GB of memory before updating to V8.1, each 
  node posts an 841 error after the update completes. 
  
  Because V8.1 allocates memory differently, the memory must be accepted by running 
  the fix procedure for the event or issue the CLI command**svctask chnodehw <id>**for 
  each node. However, only run this command for one node at a time. For more 
  information, see the Storwize V7000 IBM Knowledge Center.
