Abstract
This paper is intended to introduce IBM eServer™ pSeries® customers, IBM Business Partners, sales, marketing, and technical teams to pSeries Storage Area Network (SAN) with Linux. IBM's plans as put forth in this document are subject to change without notice.
Overview of Linux on pSeries and Storage Area Network (SAN)
The SAN hardware supported by pSeries servers running the Linux operating system is the same SAN hardware that is supported by pSeries servers running AIX 5L™. The one exception is the IBM 6227 Fibre Channel adapter, as that adapter had been discontinued since the implementation of this document.
There may be differences between AIX 5L SANs and Linux on pSeries SANs. This document is designed to explain how to implement a Linux on pSeries SAN.
Overview of IBM pSeries Servers
This document covers all pSeries servers that support the Linux operating system and the 6228 and/or the 6239 Fibre Channel adapters. For server support, please refer to the pSeries documentation found at:
http://publib.boulder.ibm.com/infocenter/pseries/v5r3/topic/
com.ibm.pseries.doc/hardware_docs/hardware.htm
.
Certain features of pSeries servers that are supported under AIX 5L are not supported under Linux. Hot-swapping of a Fibre Channel adapter is one such example. The Linux kernel does not have the capability to power off/on a PCI slot and integrate newly added hardware as dynamically as AIX 5L.
