Im trying to remove an Initiator ID from a FCP Initiator Group, but im getting the following error message:
=== DETAILS ===
LUN maps for this initiator group exist
=== CORRECTIVE ACTION ===
Please explicitly disconnect the initiator group from any LUNs connected to it.
How can i remove these Initiator IDs?

Basically, LUNs are mapped to the FCP initiator group . You need to unmap the LUN first.
filer> lun unmap <lun_path> <initiator_group>
After this, if you require to remove the node from the igroup too, use:
filer> igroup remove [ -f ] <initiator_group> <node>
By default, if lun maps exist for the initiator group, the node is not removed from the group. The -f option can be used to force the removal.

You can do this in GUI too. In the FilerView,
click on the LUN you want to unmap
then click on [Map LUN]
check the Unmap box
click Apply button
Make sure you unmap all the LUNs associated with the igroup. Goto the tree in the FilerView on the left side
click on Initiator Groups.Manage
click on the igroup you want to modify
in the Initiators box, delete the initiator(s)
click Apply button
Then, remap the LU(s) back to the igroup.
Hope that helps,

What if I want to remove an initiator from an initiator group, but I cannot offline that group. My example...I have an initiator group with all of my ESX host initiators in it, and my datastores mapped through that group. I am decommissioning an ESX box, so I want to remove the initiators from that group, as it is no longer needed. I cannot offline that goup however, as all of my virtual machines are still running through that mapping.

See the definition for the 'igroup remove' command:
igroup remove [ -f ] initiator_group node ...
Removes node (s) from an initiator group. You may use the alias for the node , set with the fcp wwpnalias command.
The operation is prohibited if there are existing LUN maps defined for that group. The -f option can be used to force node removal.
Looks like you may be able to do it with good ol' '-f' for force flag.
I hope this response has been helpful to you.
At your service,
(P.S. I appreciate points for helpful or correct answers.)
