Installing the Subsystem Device Driver on a pSeries host running Linux

This section provides the steps that you need to complete to install the Subsystem Device Driver (SDD) on a pSeries™ host running the Linux operating system.

Before you install the SDD, make sure that your DS6000™ is configured for multiport access for each LUN. To use the load balancing and path failover protection features, SDD requires a minimum of two independent paths that share the same LUN. Failover protection is not provided with a single path. A host system with a single fibre-channel adapter connected through a switch to multiple storage unit ports is considered a multipath fibre-channel connection. See IBM^® System Storage™ DS6000 Introduction and Planning Guide for more information about configuring the storage unit for the SDD.

Note: See Upgrading the Subsystem Device Driver for the Linux operating system on the pSeries host for information on upgrading the SDD.

Complete these steps to complete the installation of the SDD:

Log onto your host system as the root user.
Insert the SDD installation CD into your CD-ROM drive.
Type mount /dev/cdrom /mnt/cdrom to mount the CD-ROM drive.
Type cd /mnt/cdrom to change to the /mnt/cdrom directory.
For SUSE LINUX, type cd suse to change to the suse directory. Then type ls to display the name of the package.
Type rpm -qpi IBMsdd-1.4.0.0-6.ppc64.sles9.rpm to view all the files in the package.
Type rpm -iv IBMsdd-1.4.0.0-6.ppc64.sles9.rpm to install the SDD. This displays a message similar to the following message:
```

IBMsdd-1.4.0.0-6
