Verifying Operating System Requirements
Ensure that your operating system will support the Dual Channel SCSI RAID Enablement Card, use the
following appropriate procedure to verify your operating system requirements.
Using AIX
The Dual Channel SCSI RAID Enablement Card is supported on the following levels of AIX or higher:
v AIX 5L Version 5.1 with the 5100-04 Recommended Maintenance Package (APAR IY44478)
v AIX 5L Version 5.2 with the 5200-01 Recommended Maintenance Package (APAR IY44479)
To determine which maintenance level is installed on your system, type oslevel -r. Verify that the
maintenance level displayed is 5100-04, 5200-01, or higher. If no maintenance level is installed on your
system, the following is an example of the data that displays on your screen:
No recommended maintenance level information is available.
If updates are needed, the latest maintenance packages and update instructions can be downloaded from
the pSeries and RS/6000 Support Web site. The Web address is:
http://techsupport.services.ibm.com/server/support. Updates can also be ordered by calling IBM Support.
Using Linux
The Dual Channel SCSI RAID Enablement Card is supported on the following Linux distributions:
v Any distribution based on United Linux 1.0 Service Pack 3, such as SuSE Linux Enterprise Server 8
Service Pack 3 or newer
v Red Hat Enterprise Linux 3 or newer
v SuSE Linux Enterprise Server 9 or newer
To determine which release is installed on your system, refer to your Linux distributor's documentation. If
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/.
Note: SuSE Linux Enterprise Server 8 SP3 used the ibmsis device driver to control the PCI-X Dual
Channel RAID Enablement Card. This device driver has been replaced by the ipr device driver,
which is used on all other supported distributions. Information on using the older ibmsis device
driver is contained in "Installing the Dual Channel SCSI RAID Enablement Card using the ibmsis
Device Driver" on page 18. Refer to this section if you are still using this device driver.
