Cabling a Fibre Channel device as an MPIO device

A Fibre Channel device can be cabled to multiple adapters. There is no limit within the software.

To cable a Fibre Channel device as an MPIO device, use the following simple configuration as an example. The following is the minimum configuration that must be done; your device might require additional configuration.

  1. With the power off, install two Fibre Channel adapters.
  2. Cable the adapters to a switch or hub.
  3. Cable the device to the switch or hub.
  4. Power on the system.
  5. To verify the configuration, type the following on the command line:
    lspath -l hdiskX
    where X is the logical number of the newly configured device. The command output should display one path for each adapter you installed and the status of each.
