Migrating to Offload iSCSI for RHEL 6.9/6.10
To migrate from a software iSCSI installation to an offload iSCSI for
RHEL 6.9 or 6.10:
1. Boot into the iSCSI non-offload/L2 boot from SAN operating system. Issue
the following commands to install the Open-iSCSI and iscsiuio RPMs:
# rpm -ivh --force qlgc-open-iscsi-2.0_873.111-1.x86_64.rpm
# rpm -ivh --force iscsiuio-2.11.5.2-1.rhel6u9.x86_64.rpm
2. Edit the /etc/init.d/iscsid file, add the following command, and then
save the file:
modprobe -q qedi
For example:
echo -n $"Starting $prog: "
modprobe -q iscsi_tcp
modprobe -q ib_iser
modprobe -q cxgb3i
modprobe -q cxgb4i
modprobe -q bnx2i
modprobe -q be2iscsi
modprobe -q qedi
daemon iscsiuio
3. Open the /boot/efi/EFI/redhat/grub.conf file, make the following
changes, and save the file:
 Remove
ifname=eth5:14:02:ec:ce:dc:6d
 Remove ip=ibft
 Add selinux=0
For example:
kernel /vmlinuz-2.6.32-696.el6.x86_64 ro
root=/dev/mapper/vg_prebooteit-lv_root rd_NO_LUKS
iscsi_firmware LANG=en_US.UTF-8 ifname=eth5:14:02:ec:ce:dc:6d
rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto rd_NO_DM
rd_LVM_LV=vg_prebooteit/lv_swap ip=ibft
KEYBOARDTYPE=pc
KEYTABLE=us rd_LVM_LV=vg_prebooteit/lv_root rhgb quiet
NOTE
To retain the original contents of the inbox RPM during installation, you
must use the
-ivh option (instead of the -Uvh option), followed by
the
--force option.
