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 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 SANbox2-8c/16 Switch Management User’s Guide for information about how to change domain IDs, timeout values, and edit zoning.

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.

3.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?

Yes - Contact your authorized maintenance provider.

No - Deactivate one of the active zone sets or edit the conflicting zones so that their membership is the same. Reset the port. If the condition remains, contact your authorized maintenance provider.

Note: This can be caused by merging two fabrics whose active zone sets have two zones with the same name, but different membership.
