Hi Robin!

thanks for your inputs, I did a test with the help of the NetApp admin, which was to remove the LUN he presented onto the server, and present a bigger LUN, and to show or see the LUN on the server, I did run the following commands:
Code:
/etc/init.d/iscsi restart
iscsiadm -m session --rescan
fdisk -l | egrep '^Disk' | egrep -v 'dm-' | grep -v identifier

in this order, and the new bigger LUN show up.

The iscsi_initiator implements the kernel side of the Internet SCSI (iSCSI) network protocol standard, the user land companion is iscontrol(8), and permits access to remote virtual SCSI devices via cam(4).

FILES
The iscsi_initiator driver creates the following: /dev/iscsi used to create new sessions. /dev/iscsi%d for each new session. SEE ALSO
