Title: Immediate Commands

Hi Sai:

I dont think there are any explicit restrictions on the initiator for delivering immediate commands defined in the iSCSI spec. However, the target restriction on immediate command handling (that you mentioned) gives an idea to the initiator that if it has two outstanding immediate(one task mgt. and one non-task mgt.) commands on a connection, they will successfully complete. But if the initiator has more than two outstanding immediate commands per connection, then there is no guarantee of successful completion of the extra immediate commands by the target.

 

Hope this helps!!

Hi all,

        The iSCSI standard specifies immediate command handling (sec. 3.2.2.1) at the target and mandates the target to support atleast one Immediate Task Mgmnt. and one Immediate non-Task Mgmnt. command "per connection". This implies that initiators can have multiple (more than two) outstanding Immediate commands to the same target on other connections (in multiple connection scenario). Does the standard mandate any restriction on the initiators in handling or delivering multiple immediate commands ??.
