1 or 0 Disable Use
iscsiadm
for discov-
ery and login to targets. The
correct
qla4xxx
iface
must be used.
Discovery:
# iscsiadm -m
discovery -t st -p
<target IP> -I
<qla4xxx iface>
Login:
#iscsiadm -m node -l
To check the sessions:
# iscsiadm -m session
Since there are no
entries in Flash or firm-
ware, target manage-
ment is done by
iscsiadm
and
isc-
sid
. The driver is just
pass-through.

If login is not done automati-
cally use:
# iscsiadm -m fw -l
Since
ql4xdisable-
sysfsboot
= 0, the
driver will not log in to
boot targets. The iscsi
initiator tools (such as
iscsistart
in
RHEL) do the login to
the boot targets.

In this configuration you can use the iscsi-client from yast to add targets and login to the targets.
b
This configuration is basically compatible with older qla4xxx infrastructure in SLES 11 SP1.
