[ovirt-users] Re: iSCSI multipath with Dell Compellent
Hi,

You usually have to specify that the LUN has to be accessible to
multiple systems (e.g. like a clustered filesystem would). It's not
unusual for a system to default to allowing only one initiator to connect.
the
problem is not that not multiple initiators are unable to connect
(that runs well), but that I see the LUNs only on one of the two
controller ports, as the storage decided that the Top Controller is
currently the active one. I can login to the second controller, but that
does not present any LUNs to any of my servers.
Maybe I should have written active controller instead of active system.
