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 with any allowed VSAN.

Recovering from Link Isolation

When two switches in a fabric are merged using a TE or E port, the port may become isolated when the
active zone set databases are different between the two switches or fabrics. When a TE port or an E port
become isolated, you can recover that port from its isolated state using one of three options:
•
•
•
If after verifying the Fibre Channel name server , you still experience FSPF problems (such as
discovering remote switches and their attached resources), the fabric may have zone configuration
problems. Examples of zone configuration problems are mismatched active zone sets and misconfigured
zones within the active zone set.

Resolving a Link Isolation Because of a Failed Zone Merge Using Fabric Manager

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.
To perform a zone merge analysis using Fabric Manager, follow these steps:
Choose Zone > Merge Analysis from the Zone menu.
Step 1
You see the Zone Merge Analysis dialog box.
Select the first switch to be analyzed from the Check Switch 1 drop-down list.
Step 2
Select the second switch to be analyzed from the And Switch 2 drop-down list.
Step 3
Enter the VSAN ID where the zone set merge failure occurred in the For Active Zoneset Merge Problems
Step 4
in VSAN Id field.
Click Analyze to analyze the zone merge. Click Clear to clear the analysis data from the Zone Merge
Step 5
Analysis dialog box.

ZONE-2-ZS_MERGE_UNKNOWN_FORMAT: Unknown format, isolating interface
Explanation Interface isolated because of an unknown format in the merge request.
Set the interoperability mode to the same value on both switches.
Recommended Action
Cisco MDS SAN-OS Release 2.0(1b).
Introduced
Import the neighboring switch's active zone set database and replace the current active zone set.
Export the current database to the neighboring switch.
Manually resolve the conflict by editing the full zone set, activating the corrected zone set, and then
bringing up the link.
