Purpose
If you are using Red Hat Enterprise Linux 5, Red Hat
Enterprise Linux 6, SUSE LINUX Enterprise Server 10, or SUSE
LINUX Enterprise Server 11, the devices might be
automatically recognized by the OS hot plug function. If the
devices are recognized, the above procedure is not necessary.
• For a device added to the target for which no session is
established with the iSCSI initiator
Execute the following command to make the OS recognize the
target:
# iscsiadm -m discovery -t sendtargets -p IP-
address-of-the-target
Then, log in to the target to establish a session.
# iscsiadm -m node -T target-name -p IP-address-of-
the-target:port-number-of-the-target --login
• For a device added to the target for which a session is
established with the iSCSI initiator
Execute the following command:
# iscsiadm -m session -R
a: Host ID (Port number of the host)
b: Channel number (Bus number)
c: Target ID
d: Lun (LU number of the host)
n: host port number
driver-name: qlaxxxx (driver name in use)
When adding a device by using a QLogic HBA driver in Red Hat
Enterprise Linux AS4/ES4:
# echo "scsi-qlascan" > /proc/scsi/qla2200/1
# cat /proc/scsi/qla2200/1
# echo "scsi add-single-device 1 0 1 1" > /proc/scsi/scsi
