17.4 Install the MPP failover driver

The MPP failover driver is used. At the time of writing, in iSCSI environments, this driver is not
supported if an HBA of any kind (iSCSI, Fibre Channel, or SAS) and the iSCSI software
initiator are installed on the same host, since the MPP driver installation will detect the HBA
first, and not use the software initiator. Therefore there must not be any HBAs installed.

17.4.1 Prepare the host to install the MPP driver

The MPP driver has some prerequisite packages which must be installed first. These are the
kernel source, compiler and libraries:
– glibc-kernheaders
– glibc-headers
– glibc-devel
– gcc
– kernel-devel or kernel-smp-devel
Mount the installation source, change to the subdirectory Red Hat/RPMS that contains the
rpm packages and install the packages. See Example 17-7.
Example 17-7 Install libraries and tools
[root@hooghly ~]# mount -t nfs 172.18.0.1:/srv /mnt
[root@hooghly ~]# cd /mnt/ftp/rhel4as-i386-u5/RedHat/RPMS/
[root@hooghly RPMS]# rpm -ivh glibc-kernheaders-2.4-9.1.100.EL.i386.rpm \
glibc-headers-2.3.4-2.36.i386.rpm glibc-devel-2.3.4-2.36.i386.rpm \
gcc-3.4.6-8.i386.rpm

4:gcc

Check the kernel used on the system and install the appropriate kernel source. Most systems
will use the smp kernel, but the uniprocessor kernel or the huge memory kernel are also
possible. The kernel source for a specific kernel contains the package kernel-?-devel. For
example the kernel source of the smp kernel is included in the package kernel-smp-devel and
the binary kernel in kernel-smp. Choose the appropriate package and install the kernel
source. This sample configuration will use the smp kernel source as shown in Example 17-8.
Example 17-8 Kernel source installation
[root@hooghly RPMS]# rpm -ivh kernel-smp-devel-2.6.9-55.EL.i686.rpm
warning: kernel-smp-devel-2.6.9-55.EL.i686.rpm: V3 DSA signature: NOKEY, key ID

[root@hooghly RPMS]#
The host is now prepared - we will next install the MPP driver.
