Hey all, I am new to IBM storage ans have what I hope is a n easy question.
When I remove a host from a host group on my DS4700 where does it go exactly? One would assume “Undefined Mappings” or "Default Group" but nothing is there.
If I try and readd via “define host” the “known HBA host port identifiers” is empty. Ideas?

Sometimes the host doesn't go to the 'Default' host group, and it could be that it was deleted. You can search in the storage profile with the host port WWN and that might give you a clue.
If the host you are trying to attach is no longer on the SAN fabric/connected to the storage/powered off, its WWN will not show up in the known host port identifiers.
