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 SANsurfer Switch Manager topology display. E_Port isolation can be caused by the following:

„FL_Port is connected to another switch

„Conflicting domain IDs

„Conflicting timeout values

„Conflicting zone membership between active zone sets

Refer to the SANbox2-8c/16 Switch Management User’s 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 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.

2.Display the fabric domain IDs using the Show Domains command or the Switch data tab in the SANsurfer Switch Manager 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 SANsurfer Switch Manager Switch Properties window. Reset the port. If the condition remains, continue.

3.Compare the RA_TOV and ED_TOV timeout values for all switches in the fabric using the Show Config Switch command or the Switch data tab of the SANsurfer Switch Manager topology display. Is each timeout value the same on every switch?

„Yes - Continue.

„No - Correct the timeout values on the offending switches using the Set Config Switch command or the SANsurfer Switch Manager Switch Properties dialog. Reset the port. If the condition remains, continue.
