The WWID (NODE_ID) in Table 8 is 5000-1FE1-0007-9DD0; the four ports on the controller
pair are always arranged as shown in Figure 26. The -9DD0 WWID for the controller pair
dictates the -9DD1 through -9DD4 WWIDs for the ports.
Note: The WWID numbering scheme shown in Figure 26 is true only when the controllers are in
multibus failover mode; it is not true for transparent mode.

Step 2: Issue a SHOW OTHER Command
Check for consistency in the other controller by issuing a SHOW OTHER command. Table 9
shows a typical output from the SHOW OTHER command and highlights the information
relevant to troubleshooting.
