E_Port Isolation
A Logged-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.
