Post install instructions

You can simulate an iSCSI session by running both the 
Initiator and the iSCSI Target emulator on the same machine.


1. Stop the Initiator:

	/etc/init.d/unh_iscsi stop 

2. Execute:

	/opt/unh/iscsi/src/cmd/ini-local


   What should appear on the screen is something similar to:

   Aug  8 15:02:53 kernel: unh_iscsi_initiator: UNH iSCSI Initiator device 
		registered, major number: 253, device : 0xfd00 
   Aug  8 15:02:53 wb11 kernel: SCSI device sdb: 3710937 512-byte hdwr 
 		sectors (1900 MB)

   Where the disk device "sdb" is the next available SCSI device
   that was added to the system by the SCSI subsystem. 

   Examine /var/log/messages if the results are different.

3. The disk device created in step 2 has it's storage allocation
   as a file that resides at /tmp/scsi_disk_file_0_1 . 
   The device represents a iSCSI target.  Any operation can be 
   performed on the newly created iSCSI device :

   	fdisk /dev/sdb

         < create a partition>

         mkfs /dev/sdb1

   	mount /dev/sdb1 /mnt

	touch /mnt/myfile 

 	ls -l /mnt
	
	umount /mnt/


4. You can examine the negotiated parameters of the 
   session by viewing the /proc/scsi/iscsi_initiator/0 
   file.

5. See also:  iscsi_manage(8) and iscsi_config(8) .
 
(Note: examine ini-local. You can also run the Target emulator on another
machine if you alter the script ).
