Hello,
Are you asking for a detailed answer on the internal process or just
how to get open-iSCSI to discover and connect to an iSCSI target?
In case it's the later:
Send a "send targets" discovery request to the iSCSI target
#open-iscsi -m discovery -t st -p <ip address>:3260
Once you have the volume discovered you can request open-iscsi to log
into the volume.
#open-iscsi -m node -l (logs in all available targets or you can
specify a specific one)
Once the iSCSI initiator connects to the volume, it's handed over to
the Linux kernel as a SCSI disk. All the normal things you can do with a
disk, is now available. Partition, create filesystem, mount, etc...
Regards,
Don

Hello,
I am trying to understand how a device is discovered by the initiator
and registered at the client side. Specifically I would like to know
how does the target show up as a /dev/sd* to the client.
I see in the kernel code a iscsi_endpoint structure which holds a
device and a connection for the device. But I am not sure if and how
this endpoint is used.
Or else, where is the device structure maintained at the initiator for
a particular iscsi target?
If there is any documentation available on this, clearly I have missed
it. Please direct me to the same.
Thanks in advance.
Regards,
Aastha.
