Troubleshooting Mode
Troubleshooting Mode can be used to assist you in identifying and resolving host configuration
issues during discovery, as described in the following steps:
1. If errors occur during discovery, an error message will display at the top of the screen below the
discovery step where the errors occurred. If you receive an error message, enable
Troubleshooting Mode by selecting the Enable Troubleshooting Mode check box located
near the top of the page for each discovery step.
2. A red icon will display in the Problems column for each host for which a problem was
detected. Clicking this icon for a particular host will cause a list of troubleshooting tips to display
below the Enable Troubleshooting Mode check box. Use these tips to assist in the resolution
of configuration problems for that host.
3. You can also enter Troubleshooting Mode by clicking the link located in the error message for
one of the discovery steps. For example, if you are on discovery step 3, you can click the
“Discovery->Setup in Troubleshooting mode” link located in the step 1 error message. Clicking
this link will bring you to the step 1 page with Troubleshooting Mode enabled.
NOTE: Step 3 Troubleshooting Mode only identifies quarantined hosts.
When Troubleshooting Mode is enabled during discovery step 2 or 3, the following additional
information is provided to assist in the identification of configuration issues:
• Host OS
• CIM Extension Version
• HBA (Driver Version)
• Multipathing

About Managing McDATA and EMC Connectrix Switches
Whenever you add, remove or replace McDATA or EMC Connectrix switches in an already
discovered service processor, you must make the management server aware of those changes. After
you add these switches to the service processor, you must perform Get Details/Discovery Data
Collection. The management server obtains information about the new switches from the service
processor. See the topic, ”Adding McDATA and EMC Connectrix Switches” on page 141 for more
information about adding switches.
