There is of course no second path, and there is a fair bit of information missing that your would otherwise get from an enterprise deployment, but you get the idea. The basic procedure for configuring your system with DM-Multipath is as follows:.

We can add a device section check manufacture's documentation. It can be overridden by the -v command line option. An absolute path is required.

In RHEL 5. If set to uniform, all path weights are equal. SCSI commands with an explicit timeout, in seconds.

Lists and configures multipath devices. Hence, as a solution of such a single point of failures, Multipathing concepts comes in picture. I have always wondered how to configure the device mapper multipath package for a Linux system.

Start the multipathd service and configure the service to start after system reboots:. The second change eliminates the collection of entropy for the kernel random number generator, which has high cpu overhead when enabled for devices supporting high IOPS.

Linux Multipath Concepts and Configuration

All changes in this section take effect immediately, without rebooting for RHEL5 and 6. You can use a devnode entry in the blacklist section of the configuration file to specify individual devices to blacklist rather than all devices of a specific type.

This is not recommended, however, since unless it is statically mapped by udev rules, there is no guarantee that a specific device will have the same name on reboot. By how to load dm multipath kernel, the following devnode entries are compiled in the default blacklist; the devices that these entries blacklist do not generally support DM-Multipath.

You can specify specific device types in the blacklist section of the configuration file with a device section. For example, a WWID exception will not apply to devices specified by a devnode blacklist entry, even if the blacklisted device is associated with that WWID.

Similarly, devnode exceptions apply only to devnode entries, and device exceptions apply only to device entries. The configuration file includes a template of configuration defaults.

This section is commented out, as follows.Before setting up DM-Multipath on your system, ensure that your system has n): --find_multipaths Load the dm-multipath modules on enable (Default y).
