3.3. Configuring Storage Devices
By default, DM-Multipath includes support for the most common storage arrays that support DM-Multipath. The default configuration values, including supported devices, can be found in the
multipath.conf.defaults file.
If you need to add a storage device that is not supported by default as a known multipath device, edit the
/etc/multipath.conf file and insert the appropriate device information.
For example, to add information about the HP Open-V series the entry looks like this, where %n is the device name:
devices {
device {
vendor "HP"
product "OPEN-V."
getuid_callout "/lib/udev/scsi_id --whitelisted --device=/dev/%n"
}
}
For more information on the
devices section of the configuration file, see Section 4.5, “Configuration File Devices”.
