Resolution
Dell Unity discovers all the hosts zoned in the fabric configuration and their initiators automatically.
If the hosts are assigned to any LUNs:
1-De-attach the host from the LUN. - See Additional Info notes below.
-Go to Block > LUNs
-Choose the LUN to edit
-Within LUN properties, go to Access tab, and choose the hosts and click delete to disconnect the access.
2-Delete all the ESXi hosts.
-Go to VMware under access in the left panel
-Choose all the hosts and delete them.
3-Delete the initiators associated with the host.
4-Unity autodiscovers the ESXi hosts.
If the hosts are not assigned to any LUN(s):
Follow steps 2 through 4 above.
The Initiators conflict should be resolved.
Additional Information
**NOTICE**
Step 1 (detaching LUNs) can take a long time as each LUN on the host is a separate job in Unisphere. It is recommended to remove LUNs one by one and watch the Job tab for it to complete.
