To migrate from a non-offload interface to an offload interface:
1.
Upgrade qedi transport-supported Open-iSCSI tools such as iscsiadm,
iscsid, iscsiuio, and iscsistart.
a.
Use the following Open-iSCSI RPM package:
qlgc-open-iscsi-2.0_873.107-1.x86_64.rpm
b.
Issue the following command:
rpm -ivh qlgc-open-iscsi-2.0_873.107-1.x86_64.rpm –force
c.
To reload all the daemon services, issue the following command:
#
systemctl daemon-reload
d.
To enable and restart iscsid and iscsiuio services, issue the following
commands:
#
systemctl enable iscsid.socket
#
systemctl enable iscsid
#
systemctl enable iscsiuio.socket
#
systemctl enable iscsiuio
#
systemctl restart iscsiuio
#
systemctl restart iscsid
2.
For the RHEL 7.x OS distro
only
, complete the following steps:
a.
Create an iface record for an L4 interface:
#
iscsiadm -m iface -I qedi.00:0e:1e:c4:ca:5d -o new
b.
Update the
iface
fields in the iface records. For example:
#
iscsiadm -m iface -I qedi.00:0e:1e:c4:ca:5d -n iface.hwaddress -v
00:0e:1e:c4:ca:5d -o update
#
iscsiadm -m iface -I qedi.00:0e:1e:c4:ca:5d -n iface.ipaddress -v
192.168.91.101 -o update
# iscsiadm -m iface -I qedi.00:0e:1e:c4:ca:5d -n iface.transport_name -v qedi
-o update
# iscsiadm -m iface -I qedi.00:0e:1e:c4:ca:5d -n iface.bootproto -v static -o
update
c.
Create a target node record to use the L4 interface as follows:
#
iscsiadm -m node -T iqn.2000-05.com.3pardata:2121002ac01b6f1 -p
192.168.91.30:3260 –I qedi.00:0e:1e:c4:ca:5d –o new
d.
Edit the following iscsid configuration file:
# vi /usr/lib/systemd/system/iscsid.service
Locate the following lines:
