Install The Mpp Driver - IBM DS3000 Introduction And Implementation Manual

Draft Document for Review August 30, 2007 12:59 am

17.4.2 Install the MPP driver

1. Download the driver from http://www.lsi.com/rdac/ds3000.html. 21.7, "Install Linux
RDAC" on page 517 15.4, "Install RDAC for Linux" on page 336 contain more details of
installing this driver.
2. Unpack the driver archive into a local directory for example /root as shown in
Example 17-9. Note that the actual archive name changes to match the actual version.
Example 17-9 Unpack archive
[root@hooghly ~]# tar xvfz rdac-LINUX-99.01.B5.64-source.tar.gz
3. A subdirectory linuxrdac-<version number> is created. Change to this directory,
Example 17-10.
Example 17-10 Change to unpacked directory
[root@hooghly ~]# cd linuxrdac-99.01.B5.64
[root@hooghly linuxrdac-99.01.B5.64]#
4. If an older MPP driver version is installed, run make uninstall in this directory. A
message is shown by make to notify if there is an old version installed on the system when
an operation other than make uninstall or make clean is executed.
5. Run the make command followed by make install in the MPP driver source directory to
compile the driver, as shown in Example 17-11. The compiler output has been
abbreviated, as indicated by the three dots.
The make install phase scans for available HBAs. As already mentioned it is required that
no HBAs are installed when MPP is used to provide failover functionality for the iSCSI
software initiator together with a DS3300. It is important that the iSCSI software adapter is
found and the question "Do you want MPP to manage an iSCSI storage array?" is
asked. Answer "Do you want to continue (yes or no)?" with yes to proceed. If an HBA
is found, the MPP will detect this instead of the iSCSI software initiator - remove the HBA
and try again.

[root@hooghly linuxrdac-99.01.B5.64]# make && make install
