3.3. Adding Devices to the Multipathing Database

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:

devices {

device {

vendor "HP"

product "OPEN-V."

getuid_callout "/sbin/scsi_id -g -u -p0x80 -s /block/%n"

}

For more information on the devices section of the configuration file, see Section 4.5, “Configuration

File Devices”.
