lsdev -d pci_mux0
(pci_mux0 is the driver name of the PCI Mux.)
Naming Scheme for emux_diag and emux_stty
Because there are as many as eight PCI buses (Module ID), emux_diag and emux_stty use a
combination of PCI bus and slot number as the naming scheme for “Slot” to uniquely identify
a card for V-Class servers.
In the example below, for board 4, Slot 40, the first digit (4 of 40) is the PCI bus number (or
Module ID) and the second digit (0 of 40) is the slot number in that bus (the value is shown in
bold in the example).
# emux_stty -c
Board 1 id 0x8 PMUX-64P Slot 01
Board 2 id 0x8 PMUX-64P Slot 11
Board 3 id 0x8 PMUX-64P Slot 12
Board 4 id 0x8 PMUX-64P Slot 40
# emux_diag
