This section demonstrates the effect of the ql4xdisablesysfsboot parameter 

under different adapter boot modes. 

# iscsiadm -m iface -I qla4xxx.00:c0:dd:07:59:f2.ipv4.0 -n 
iface.ipaddress  -v 10.0.10.183 -o update
# iscsiadm -m iface -I qla4xxx.00:c0:dd:07:59:f2.ipv4.0 -n 
iface.subnet_mask -v 255.255.0.0 -o update
# iscsiadm -m iface -I qla4xxx.00:c0:dd:07:59:f2.ipv4.0 -n 
iface.gateway -v 10.0.0.1 -o update
# iscsiadm -m iface -I qla4xxx.00:c0:dd:07:59:f2.ipv4.0 -o apply

Use the following sysfs path to check if the IP address has been applied:

/sys/class/iscsi_host/host<Number>/ipaddress

 shows the various configurations one can have, as well as the 

iscisadm commands or yast tool to use to check iSCSI sessions. 

For target discovery and login to work, the adapter’s IP address must be 
configured using either BIOS settings or iscsiadm. The following examples 

show the iscsiadm commands to use to set the IP address.

1

Non-Boot 
from SAN

Target info 
is in the 
firmware 
(set up 
using the 
BIOS)

1 or 0

Disable

To check sessions 

# iscsiadm -m session 

Since the target info is 
in the firmware, keep 
ql4xdisablesysfs-
boot set to 1. The 

driver does the login to 
the target.
