Migrating to Offload iSCSI for SLES 12 SP1/SP2
To migrate from a software iSCSI installation to an offload iSCSI for
SLES 12 SP1/SP2:
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 qlgc-open-iscsi-2.0_873.111.sles12p2-3.x86_64.rpm --force
# rpm -ivh iscsiuio-2.11.5.3-2.sles12sp2.x86_64.rpm --force
2. Reload all the daemon services by issuing the following command:
# systemctl daemon-reload
3. Enable iscsid and iscsiuio services (if they are not already enabled) by
issuing the following commands:
# systemctl enable iscsid
# systemctl enable iscsiuio
4. Issue the following command:
cat /proc/cmdline
5. Check if the OS has preserved any boot options, such as ip=ibft or
rd.iscsi.ibft
.
 If there are preserved boot options, continue with Step 6.
 If there are no preserved boot options, skip to Step 6 c.
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.
