IBM DS8000 manual Linux on IBM iSeries

For more information on running AIX in an i5 partition, refer to the i5 Information Center at:

Note: AIX will not run in a partition on earlier 8xx and prior iSeries systems.

Linux on IBM iSeries

Since OS/400 V5R1, it has been possible to run Linux in an iSeries partition. On iSeries models 270 and 8xx, the primary partition must run OS/400 V5R1 or higher and Linux is run in a secondary partition. For later i5 systems (models i520, i550, i570 and i595), Linux can run in any partition.

On both hardware platforms, the supported versions of Linux are:

￿SUSE Linux Enterprise Server 9 for POWER

(New 2.6 Kernel based distribution also supports earlier iSeries servers)

￿RedHat Enterprise Linux AS for POWER Version 3

(Existing 2.4 Kernel based update 3 distribution also supports earlier iSeries servers)

The DS8000 requires the following iSeries I/O adapters to attach directly to an iSeries or i5 Linux partition.

￿0612 Linux Direct Attach PCI

￿0626 Linux Direct Attach PCI-X

It is also possible for the Linux partition to have its storage virtualized, whereby a partition running OS/400 hosts the Linux partition's storage requirements. In this case, if using DS8000, they would be attached to the OS/400 partition using either of the following I/O adapters:

￿2766 2 Gigabit Fibre Channel Disk Controller PCI

￿2787 2 Gigabit Fibre Channel Disk Controller PCI-X
