If a Port Status LED shows an error indication, review the alarm log for messages regarding the affected port. You can inspect the alarm log using the Alarm data tab in SANbox Manager faceplate display or the Show Alarm command. Pertinent alarm log messages will point to one or more of the following conditions:
■E_Port isolation
■Excessive port errors
5.1.2.1
E_Port Isolation
A Port Status LED error indication is often the result of E_Port isolation. An isolated E_Port is indicated by a red link in the SANbox Manager topology display. E_Port isolation can be caused by conflicting domain IDs, conflicting timeout values, or conflicting zone membership between active zone sets. Refer to the
Review the alarm log and do the following to diagnose and correct an isolated E_Port:
1.Display the fabric domain IDs using the Show Domains command or the Switch data tab in the SANbox 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 SANbox Manager Switch Properties window. Reset the port. If the condition remains, continue.
2.Compare the RA_TOV, ED_TOV, RT_TOV timeout values for all switches in the fabric using the Show Config Switch command or the Switch data tab of the SANbox 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 SANbox Manager Switch Properties window. Reset the port. If the condition remains, continue.
