Multiple zones getting created with same initiator and target pair with Brocade Zone Manager enabled and pre-zoning

[deepali verneya]

BUG Description :

Step to reproduce:
1. Disable auto-zoning
2. Clear all configurations from switch .(use cfgclear and thn cfgsave)
3. Create zone with one initiator and one target and save the configuration.
4. Do Volume attach
5. Enable autozoning using BCZM/Configure Brocade zone manager.
6. Create 3PAR FC volume
7. Attach volume to instance

Observation:
After the autozoning is enabled, new zone is getting created with a different name even though the initiator and the target is the same.

Expected Behavior:
Brocade zone manager should not create a different zone, if zone already exist with same initiator and target pair in switch – be it manually created or created by zone manager
