Notes for /etc/sysconfig/kernel file settings
When using SUSE Linux Enterprise Server 11 (Service Pack 1 or later), the "/etc/sysconfig/kernel" file must have
"mpdh" at the beginning of the INITRD_MODULES line for the Multipath Driver to operate properly.
■
Notes for required installation packages
•
For SUSE Linux Enterprise Server 9 or SUSE Linux Enterprise Server 10
The gcc, kernel-source, and make packages must be installed. Execute the following commands to check if
these packages are installed.
Install any of the packages listed above that are not installed.
•
For SUSE Linux Enterprise Server 11
In addition to the packages listed above, the kernel-xxxx-devel package must also be installed. kernel-
xxxx-devel can be kernel-default-devel or kernel-pae-devel. Which package should be installed depends
on the environment that is used.
Use the following command to check which environment should be used.
"default" or "pae" is displayed, indicating the environment that should be used.

Notes for an environment in which Java is installed
The following error may be displayed when executing the "mpdpkgadd", "mpdpatchadd",
"mpdsetup", or "mpdpkgrm" commands in a Java environment.
This error can be ignored. The operation of the Multipath Driver is not affected since it does not use "jexec".
■
Notes for using a KVM environment
The Multipath Driver can be used with a KVM environment for Red Hat Enterprise Linux 6 or Red Hat
Enterprise Linux 7.
Note that the Multipath Driver can only be installed to the kernel of the host that installs KVM. Do not install
the Multipath Driver in a guest OS.
