McDATA® 4Gb SAN Switch for HP p-Class BladeSystem installation guide 41
E_Port isolation
E_Port isolation can be caused by the following:
• Security failure
• Port type is F_Port or FL_Port and is connected to another switch (should be configured as G or GL)
• Conflicting domain IDs
• Incompatible fabric interop modes
• Conflicting timeout values
• Conflicting zone membership between active zone sets
See the McDATA 4Gb SAN Switch for HP p-Class BladeSystem user guide or the McDATA 4Gb SAN
Switch for HP p-Class BladeSystem command line interface guide for information about how to change
domain IDs, timeout values, and edit zoning.
Using the McDATA Web Server, review the event browser and perform the following procedure to
diagnose and correct an isolated E_Port:
1. Check the event browser for an alarm about an invalid attach on the affected port. Does such an alarm
exist?
• 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. Check the event browser for a repeating alarm about an unsupported E_Port command on the port.
Does such an alarm exist?
• Yes—The port is configured as an FL_Port and connected to another switch. Correct the port
connection or the port type.
• No—Continue.
3. Display the fabric domain IDs using the CLI and Show Domains command, or click the Switch tab in
the McDATA Web Server. Are all domain IDs in the fabric unique?
•Yes—Continue.
• No—Correct the domain IDs on the offending switches using the CLI and Set Config Switch
command or the McDATA Web Server Switch Properties dialog, then reset the port. If the condition
remains, continue.
4. Compare the RA_TOV and ED_TOV timeout values for all switches in the fabric using the CLI and
Show Config Switch command, or click the Switch tab in McDATA Web Server. 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 McDATA Web Server Switch Properties dialog, then reset the port. If the condition
remains, continue.
5. Use CLI and the Zoning Active command to display the active zone set on each switch, or click the
Active Zoneset tab in the McDATA Web Server. 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 their membership is the
same, then reset the port. Also check default zone status (if applicable). Is the default zone status
displayed with the active zone set? If the condition remains, contact your authorized maintenance
provider.
NOTE: E_Port isolation can be caused by merging two fabrics whose active zone sets have two
zones with the same name, but different membership.
