boot for the adapter as follows:
a. Select the adapter port, and then select Device Level Configuration.
b. On the Device Level Configuration page, for the Virtualization Mode,
select NPAR.

UEFI iSCSI.

Migrating to Offload iSCSI for SLES 11 SP4
To migrate from a software iSCSI installation to an offload iSCSI for
SLES 11 SP4:
1. Update Open-iSCSI tools and iscsiuio to the latest available versions by
issuing the following commands:
# rpm -ivh qlgc-open-iscsi-2.0_873.111.sles11sp4-3.x86_64.rpm --force
# rpm -ivh iscsiuio-2.11.5.3-2.sles11sp4.x86_64.rpm --force
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.
