Look in the README file for ' 5.1 How to setup iSCSI interfaces (iface) for binding' > 2.The session id always get incremented after each new login.

The SCSI middle-layer is the one that gives us the 'host' number which is what we use. Every time you open/tear down a session, we open/tear down an SCSI "Host" and the SCSI layer gives us a host-number. > 3. How to persistently map iscsi target to fixed sd<X> id ? Use multipath or convert the scsi_id to retain a cache so that when it returns a value the device-mapper can re-create a /dev/mapper/XX to point to the old block device. Multipath is probably a better choice - as that is easily installed on most distros and it automaticly map block devices to uniquely identified devices that won't change between reboots. > > for third Question, I came across couple of threads in forum and IET > for similar issue.
