Verifying Utility Version

The Dual Channel SCSI RAID Enablement Card requires Version 1.0.3 (or later) of the iprconfig utility for

2.4based kernels and version 2.x.x for 2.6 based kernels. To verify the version number of the iprconfig utility, do the following:

1.If necessary, log in as root user.

2.Type:

iprconfig --version

Press Enter.

The following is an example of the data that displays on your screen:

iprconfig: Ver. 1 Rev. 0.3

iprconfig: 2.0.10 (May 23, 2004)

Note: The version displayed in the example might be different from the output displayed on your screen.

If the version displayed is not at the recommended level and updates are needed, obtain them from your Linux distributor or download them from the IBM StorageIO Web site. The Web address is: http://www-124.ibm.com/storageio/ipr/.

Installing the Downloaded Device Driver and Utility Software

Software required for the Dual Channel SCSI RAID Enablement Card is usually installed when the Linux operating system is installed. Software installation is not necessary unless verification has failed.

If it is necessary to install software, obtain it from one of the following sources in the order listed:

1.Your supported Linux operating system CD-ROM

2.Your Linux distributor

3.Online at the IBM StorageIO Web site: http://www-124.ibm.com/storageio/ipr/

After downloading the needed software package, install the software by continuing with the instructions in this section. Then, return to “Verifying Linux Software Installation” on page 13, and follow the procedure to ensure that the installation was successful.

Installing Device Driver Software

The ipr device driver is available in the base 2.6 kernel as of Version 2.6.7-rc1. Additional driver updates may be available on the IBM StorageIO Web site as mentioned above. These patches may be downloaded and installed like any other kernel patch. The ipr device driver is not in the base 2.4 kernel and must be downloaded from http://www-124.ibm.com/storageio/ipr/ in the form of a kernel patch if not available as part of your distribution.

If you downloaded the ipr device driver patch, do the following:

1.Turn on the power to your system unit.

2.At the system prompt, log in as root user.

3.Uncompress and apply the patch by typing:

cd /usr/src/linux

wget http://www-124.ibm.com/storageio/ipr/patch-2.4.26-ipr-1.0.5.gz gunzip patch-2.4.26-ipr-1.0.5.gz

patch -p1 < patch-2.4.26-ipr-1.0.5

4.Compile and install the device driver. If you are compiling a 2.4 kernel, make sure IBM Power RAID SCSI support is selected. If you are compiling a 2.6 kernel, make sure IBM Power Linux RAID adapter support is selected.

5.Reboot your system.
