Re: Connection Recovery in case of a single connection in a session

["Julian Satran" <Julian_Satran@il.ibm.com>]

Yes and No. You should be able to open a new connection but that can be AS A REPLACEMENT of the old connection and reassign.
The only unfortunate case where you may have to have 2 connection capability is when your iSCSI time-outs are shorter than the TCP time-outs and
either initiator or target will not detect a failed TCP before the iSCSI state disappears.

Target should support opening a second connection even though they do not support multiple connections in full feature phase. The purpose of second connection is to reassign the tasks.

This recovery requires the ability to support more than one
connection in a session.  Once the first connection is logged
out, its tasks are gone.  An implementation that does not
support multi-connection sessions cannot do this sort of
recovery.
