[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] iSCSI: Negotiating a parameter more than onceJulian, The following text appears in 4.3 (page 78 just before 4.3.1): Neither the initiator nor the target should attempt to negotiate a parameter more than once during login. If detected by the target this MUST result in a Login reject (initiator error). The initiator MUST drop the connection. and nearly the same text in 4.4 (page 85 near the end): Neither the initiator nor the target should attempt to negotiate a parameter more than once during any negotiation sequence without an intervening reset. If detected by the target this MUST result in a Reject with a reason of "protocol error". The initiator MUST reset the negotiation as outlined above. This is confusing partly because "negotiate" seems to be generally used covering both negotiations and declarations and in some cases covering only negotiations. It isn't clear in which sense it is used. If the text above applies only to negotiated values, then it would be allowable to send parameters such as Initiator Name, SessionType, and MaxRecvDataSegmentLength over which doesn't seem to be a good idea. However, there are other declarative parameters which are sent multiple times - SendTargets where there are multiple targets or multiple addresses for a target requires sending the same parameter multiple times. Perhaps the text should be changed to: Neither the initiator nor the target should attempt to declare or negotiate a parameter other than TargetName, TargetAlias or TargetAddress more than once....
