) 11 SP2, the QLogic qla4xxx driver (iSCSI driver for
Linux) supports the Open-iSCSI tool iscsiadm. As a result, iscsiadm can now
be used to perform management functions (configuring network settings,
managing iSCSI targets, and so on) on QLogic 4000 Series 1GbE iSCSI Adapters
and 8200 Series 10GbE Converged Network Adapters.
What is in This Guide
This document describes the differences between the legacy (IOCTL-based) and
Open-iSCSI management models of the QLogic qla4xxx driver, and provides
brief guidelines for migrating from the legacy to the Open-iSCSI model.
This preface specifies the intended audience, lists related documents, describes
the typographic conventions used in this guide, and provides technical support
and contact information.
The remainder of this user’s guide is organized into the following chapters:
Section 1 Legacy vs. Open-iSCSI describes the major differences between
the legacy driver which has an IOCTL-based interface for user space
application communications, and the Open-iSCSI model.
Section 2 Boot from SAN provides information on configuring Boot from
SAN (BFS) when migrating to the Open-iSCSI model.
Section 3 Open-iSCSI User’s Guide provides a User’s Guide for
Open-iSCSI.
Section 4 Known Issues provides a list of currently known issues.
Intended Audience
This document is intended for end users who manage QLogic 4000 Series iSCSI
adapters or 8200 Series Converged Network Adapters on Linux (RHEL 6.2, SLES
11 SP2, or later), using the IOCTL-based management model.
