For the error messages with the highest internal priority, perform corrective actions by running  fix procedures. Click the  Run Fix  button (see Figure 5-37 on page 152). The fix procedure  wizard opens, as shown in Figure 5-38. The wizard guides you through the troubleshooting and fixing process from a hardware or  software perspective. If you determine that the problem cannot be fixed without a technician’s  intervention, you can cancel the procedure execution at any time.  For more information about fix procedures, see Chapter 13, “RAS, monitoring, and  troubleshooting” on page 673. The Performance pane reports the general system statistics that relate to processor (CPU)  utilization, host and internal interfaces, volumes, and MDisks. You can switch between MBps  or IOPS, and drill down in the statistics to the node level. This capability might be useful when  you compare the performance of each control canister in the system if problems exist after a  node failover occurs (see Figure 5-39 on page 154). 5.4.3 Performance  Figure 5-38 Performing fix procedure Chapter 5.
