Re: LU access through an iSCSI session

[meth@il.ibm.com]

Pierre,
All accessible LUs may be accessed through all TCP connections of a single
session. The session is conceptually the "service delivery port."  LU
numbers are identical across all of the TCP connections of a single iSCSI
session.
Each iSCSI SCSI Command PDU must specify the LUN to which it is referring,
and it doesn't matter across which TCP connection (of the same session) it
is sent.

Subject:  LU access through an iSCSI session




Julo,


Thinking about what could be an implementation of an iSCSI
session, several questions came to my mind for which
i was unable to find an answer in the draft.

1) Do commands directed to a particular LU through a session are
able to use any of the TCP connections within the  session?

As the TCP connections could connect to various "service delivery ports"
it is
not guarantee that a particular LU is visible through all the
connections.


2) Do commands directed to a particular LU through a session
need to be associated to different LUNs depending on the TCP
connection used or is it always the same LUN for all
the connections?
