RE: iSCSI protocol - use of SendTargets



Hi all,
 
Unfortunately my innuendo was poorly worded, so I apologize to all readers on this list who took offence at my comments since the intent was not malicious or disrespectful.
 
Parav, did the specific sections I pointed out help with your understanding? If you have anything you are not sure of this is the forum to ask in.
 
Cheers
Ken

Parav,

Nobody minds any sort of question. As for me getting annoyed it was just about an unwarranted innuendo by Ken.

RE: iSCSI protocol - use of SendTargets





Hi all,

I apologize for asking such basic question on this mailing list. I would read the iSCSI RFC 3720 by myself.

I thought of sharing and gaining knowledge through this mailing list faster, but now I understand it may not be the perfect for starters.

Thanks a lot for your the kind support, suggestions and information.

Regards,
Parav Pandit

Hard to comment on your statement. Sounds more like a group "denigration" of the authors - and I don't know about any of us doing what you suggest.

I am a bit uneasy about this statement - to say the least.

Hi Julo,

 

I don't know how many third party iSCSI 'Big Dummies' guides are out there, however, since RFC3720 succinctly describes the fundamentals of the iSCSI model I recommended that as the first choice.

 

I'd have no objection if the author of RFC3720 wanted to advertise his publication here! ;-)

 

Cheers

Ken

I agree with Ken on the reading below. You may have alredy figured this out but just to try to give a simple answer to your question ... suppose you have built a box that has several targets each with different ip addresses; the user at the initiator could just give one of the ip addresses as the "discovery address"; this could be the address of only one of the targets; the initiator can then log on as a discovery session using that address and use SendTargets to find the names and addresses of all targets.

Hi Parav,


Before any author shamelessly plugs their iSCSI publications, I suggest you have a quick re-read of RFC3720.


In particular, section 3.4 pages 37-40 cover some really important concepts that I think will help your understanding. Then jump to the start of section 3, page 17 for more concepts and definitions.


The specifics of the SendTargets command are in Appendix D.


HTH

iSCSI protocol - use of SendTargets


Hi,

I am new to iSCSI protocol and gearing up.
Is this the right mailing list to ask questions related to  iSCSI protocol?

if yes,

1.  iSCSI target is identified by the network portal (IP + port).
So once the iSCSI target is identified by the network portal and Login to it is successful, why do we need to ask for SendTargets command?
TargetName and TargetAddress returned are immaterial (because we already know the target address to which we have logged-in), unless there are multiple addresses for them and failover is required used.
Or it is used for communicating different TCP port on which initiators can send TUR, Inquiry, Read, Write commands?

What is the expected information from the target in response to SendTargets command?

Regards,
Parav Pandit
