Troubleshooting E port Isolation using Fabric Manager

To troubleshoot E port isolation due to zoning using Fabric Manager, follow these steps:
Step 1 Choose Switches > Interfaces > FC Physical to verify that the E port did not come up because of a zone
merge failure.
Zoning information exists on a per VSAN basis. Therefore, for a TE port, it may be necessary to verify
Note
that the zoning information does not conflict for any allowed VSAN.
Step 2 Select Zone > Edit Local Full Zone Database to verify the zoning configuration.
Step 3 Use one of the following two approaches to resolve a zone merge failure:
•
•
If the isolation is specific to one VSAN and not on an E port, the correct way to issue the cycle up or
Step 4
down is to remove the VSAN from the list of allowed VSANs on that trunk port, and reinsert it.

b.
c.
Note
Using the Zone Merge Analysis tool in Fabric Manager, the compatibility of two active zone sets in two
switches can be checked before actually merging the two zone sets. Refer to the Cisco MDS 9000 Fabric
Manager Configuration Guide for more information.

Choose File > Restore from the Edit Local Full Zone Database dialog box to overwrite the zoning
configuration of one switch with the other switch's configuration.
The Restore option overwrites the local switch's active zone set with that of the remote switch.
If the zoning databases between the two switches are overwritten, you cannot use the Restore
option. To work around this, you can manually change the content of the zone database on either of
the switches using the Edit Local Full Zone Database, and then choose Switches > Interfaces > FC
Physical and select down and then up on the Admin Status drop-down menu for the isolated port.
Choose Switches > Interfaces > FC Physical and select the Trunk Config tab.
Remove the VSAN from the Allowed VSAN list and click Apply Changes.
Add the VSAN back to Allowed VSAN list and click Apply Changes.
We recommend that you do not disable and then enable a T or TE port. This would affect all the
VSANs crossing the EISL instead of just the VSAN experiencing the isolation problem.
