Enabling and Disabling Multipathing in
the Linux Operating System
This section describes how to enable and disable multipathing in supported versions
of the Linux operating system.

▼ To Enable Multipathing in Linux

1. Attach a J4200 or a J4400 to a server with a supported version of Linux installed.
2. On the server, edit or create the /etc/multipath.conf file.
3. Reboot the server.
4. After the reboot, make sure that the OS discovers all the disks in the
J4200/J4400 arrays either by using the Linux commands, fdisk or lsscsi.
5. Partition any disks you want to the desired sizes.
6. Use the Linux command modprobe to add the loadable kernel modules dm-
multipath and dm-round-robin.
# modprobe dm-multipath
# modprobe dm-round-robin
