Table 12-5 describes the measures to take when an SDV merge fails and ISL comes up.
Symptom SDV merge fails when the ISL comes up.
Zone Activation Fails in a SDV Zone
Symptom Zone activation fails in a SDV zone.
If a zone activation fails in a SDV zone, enter the show zone internal sdv-table command to view the
physical-virtual mapping maintained in the zone server. Devices should be zoned so that they cannot
communicate to both the real device and its virtual component.
Table 12-5 SDV Merge Fails When ISL Comes Up
Symptom Possible Cause Solution
SDV merge fails
when ISL comes up.
Configuration mismatch in the merging
fabrics.
To forcefully recover from an SDV merge failure due to an
ISL not coming up, perform an empty commit from one of
the involved fabrics.
Note This should not only remedy name and pWWN
mismatches, but also a device alias failure.
Virtual device name and pWWN
mismatch in the merging fabrics.
Virtual device name and FC ID
mismatch in the merging fabrics.
