If the AIX or Linux operating system is installed on a disk array, the RAID disk array may be used as the
boot source.
You may receive this adapter preinstalled in a hot-swap carrier for use in certain system types. This carrier
allows the adapter to be installed and removed without removing the top cover of the system. For handling
instructions, refer to the user's guide for your system. If the adapter does not fit in your system, the handle
may need to be removed in order for the adapter to fit properly. The handle can be removed by referring
to "Preparing for a PCI Slot-Length Installation" on page 3.
The PCI-X Dual Channel Ultra320 SCSI RAID Adapter conforms to the American National Standards
Institute (ANSI) SCSI-2 standard and the PCI local specification, revision 2.2.
Verifying Operating System Requirements
To ensure that your operating system will support the PCI-X Dual Channel Ultra320 SCSI RAID Adapter,
use the following procedure to verify that your operating system requirements.
Using AIX
The PCI-X Dual Channel Ultra320 SCSI RAID Adapter 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 PCI-X Dual Channel Ultra320 SCSI RAID Adapter 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 Ultra320 SCSI RAID adapter. 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 PCI-X Dual Channel Ultra320 SCSI RAID Adapter using
the ibmsis Device Driver" on page 22. Refer to this section if you are still using this device driver.
