Step 5 Use the show system internal sysmgr service all command on the standby supervisor to determine
whether or not any process is experiencing excessive restarts. (See Example 4-12.)
Note This command may not be available if the standby supervisor is at the loader> prompt.
Example 4-12 Finding Excessive Restarts

Looking at the standby supervisor in Example 4-12 shows that the crossbar (xbar) software component
has been restarted 23 times. This has probably prevented the standby from initializing properly.
Step 6 Use the reload module command to restart the standby supervisor. If the restart fails, use the reload
module 6 force-dlnd command from the active supervisor to force the standby supervisor to netboot off
of the active supervisor.
