[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] RE: iSCSI: DLB's [T.6] 2.3 iSCSI Session TypesDavid, The issue that came up before was if a discovery session could be kept open, why not allow the initiator and target to send NOPs, and allow the target to send Async messages when new targets become available? I don't mean to bring up this issue again at this stage, but using "MAY" leaves room for implementations that want to support this. If we allow NOP and Async PDUs on a discovery session, then changing "MAY" to "MUST" will be fine. -Ayman > -----Original Message----- > From: Black_David@emc.com [mailto:Black_David@emc.com] > Sent: Monday, July 08, 2002 9:19 AM > To: aghanem@cisco.com; ips@ece.cmu.edu > Subject: RE: iSCSI: DLB's [T.6] 2.3 iSCSI Session Types > > > Ayman, > > Something needs to be cleaned up here, as the current text appears > to allow all types of iSCSI PDUs on a discovery session.
