The following hosts are already connected to a different storage group

Question

I got several sgs that I want to be able to share luns with. but when I add the host into another sg, I got a warning saying The following hosts are already connected to a different storage group: Connecting these hosts to the current storage group will cause them to be disconnected from the other storage group. Once disconnected these hosts will no longer be able to access LUNs assigned to the other storage group. This operation will add the following hosts to this storage group: Each host will be able to write to all LUNs within the storage group.

you should only present LUNs to multiple hosts if this some sort of cluster (ESX, Microsoft Failover Clustering ..etc)

tdubb please go back and close the threads you opened previously. host can only belong to one storage group, LUNs can be added to multiple storage groups.

ok

but got this warning

LUN 79 is already contained in a storage group.

Adding a LUN to multiple storage groups is not a recommended configuration because this will allow multiple hosts to have simultaneous access to the LUN.
