4–Diagnostics/Troubleshooting FC Port Diagnostics

E_Port Isolation

ALogged-In LED error indication is often the result of E_Port isolation. An isolated E_Port is indicated by a red link in the Enterprise Fabric Suite 2007 topology display. E_Port isolation can be caused by the following:

Security failure

FL_Port is connected to another switch

Conflicting domain IDs

Conflicting timeout values

Conflicting zone membership between active zone sets

Refer to the SANbox 9000 Series Enterprise Fabric Suite 2007 User Guide or the SANbox 9000 Series Stackable Chassis Switch Command Line Interface Guide for information about how to change domain IDs, timeout values, and edit zoning. Review the event browser and do the following to diagnose and correct an isolated E_Port:

1.Does the event browser show an invalid attach alarm for the affected port?

Yes - Review the ISL group in the active security set to ensure that the membership includes the necessary ports and that the secrets on all switches are correct.

No - Continue.

2.Does the event browser show a repeating alarm about an unsupported E_Port command on the affected port?

Yes - The port is configured as an FL_Port and connected to another switch. Correct the port connection or the port type.

No - Continue.

3.Display the fabric domain IDs using the Show Domains command or the Switch data tab in the Enterprise Fabric Suite 2007 topology display. Are all domain IDs in the fabric unique?

Yes - Continue.

No - Correct the domain IDs on the offending switches using the Set Config Switch command or the Enterprise Fabric Suite 2007 Switch Properties window. Reset the port. If the condition remains, continue.
