Essentials | Document ID
3 Troubleshoot the MX7000 discovery issues in OpenManage
Enterprise
If the complete chassis discovery feature does not successfully auto-discover the required devices associated
to the MX chassis, you may find more details in Application Logs in the Logs portal. As shown in Figure 10,
details are included in the Application Logs if OpenManage Essentials finds an invalid IP address, the IP
address is in exclusion list, and others.
Application Logs messages indicating the issues in discovering devices associated to the MX
chassis while performing the complete chassis discovery
If the MX chassis is discovered as unknown device in OM Essentials, then ensure the following:
MX chassis web server certificate is valid.
The REST credentials are valid for the MX chassis.
3.1 FAQs
1. Question—How do I use the complete chassis discovery feature if the MX chassis has one credential
and all the iDRACs have other common credentials?
Answer—You can discover the MX chassis and blade servers by following the instructions in step 10 and
11 of the Discover complete MX chassis in OpenManage Essentials section.
2. Question—If each blade server in the MX chassis has different credentials, how do I use the complete
chassis discovery feature to discover all the blade servers?
Answer—The complete chassis discovery feature does not have provision to enter different credentials
for each blade server. To auto-discover all blade servers by using the complete chassis discovery feature,
all iDRACs in MX chassis must have the same credentials.
3. Question—The blade servers in a MX chassis are not getting discovered while using the MX Chassis
Discovery – All Components filter. How can I troubleshoot further?
Answer: See the Application Logs page after the discovery and inventory is completed and ensure that
the MX chassis components have valid IP address and are not in the exclusion range.
4. Question—I discovered the Dell chassis and its components by using the MX Chassis Discovery – All
Components filter of Guided Wizard. I notice that the discovery range group of the previously discovered
blade servers has moved within the discovery range group of the chassis. However, the blade servers
that I had discovered earlier are still inventoried using the SNMP protocol. What should I do?
