RE: SCSI-Target ID in ISCSI

Shesha,

I'm not clear on why you bring a router and its IP address into this question. An iSCSI server or client (HBA) will have an IP address (or in some cases it may have multiple IP addresses). 

An iSCSI server may contain multiple targets but when an iSCSI session is created, the initiator identifies the target for that session using the iSCSI Target name. Once that session is created, the target is accessed using SCSI commands and the process of reading disk or LUN identifications would be done the same as over any other SCSI transport.

Subject: SCSI-Target ID in ISCSI


Hi All,
  I have a disk array. Each disk in that array has a saperate ID. The 
devices are internally conncted using SCSI. If I have iSCSI HBA on the 
array, (with a router attached to it). The router will have an IP address. 
Say IP Address + target ID indentifies uniquily a disk.

How is the SCSI-Target ID(NOT the LUN#) is transmitted from the 
iSCSI-Initiator to the iSCSI-Target.

Thanks in advance for any of your comments
Shesha
