RE: iSCSI protocol - use of SendTargets

["Sandars, Ken" <ken_sandars@xxxxxxxxxxx>]

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.

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

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

Ken - what exactly does "Before any author shamelessly plugs their iSCSI publications, I suggest 
you have a quick re-read of RFC3720. " 
reffer to? - Julo

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.

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
