the Show Alarm command. Pertinent alarm messages will point to one or more of the following conditions:

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 a security failure, conflicting domain IDs, conflicting timeout values, or conflicting zone membership between active zone sets. Refer to the SANbox2-64 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 an alarm for an invalid attach 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.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.

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 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 dialog. Reset the port. If the condition remains, continue.

4.Display the active zone set on each switch using the Zoning Active command or the Active Zoneset tab of the SANbox Manager topology display. Compare the zone membership between the two active zone sets. Are they the same?
