It is a good practice to verify that you have the multipathing packages that enable you to use DM-Multipath. These packages are part of your Linux distribution.
Steps
- Use the rpm -q command to display information about the name and version of the DM-Multipath package that you have installed.
| If you are using... |
Enter the following command... |
|---|
| Red Hat Enterprise Linux |
- rpm -q device-mapper
- rpm -q device-mapper-multipath
|
| SUSE Linux Enterprise Server |
- rpm -q device-mapper
- rpm -q multipath-tools
|
- If you do not have the required packages, get a copy of your operating system RPM and install the multipathing package.
