Specifies the target device which can be a downlink card in a host slot, an
External I/O Expansion Unit, or a FRU in an External I/O Expansion Unit.
The downlink card is identified by the hostpath to the card.
hostpath is platform dependent and indicates the path to the slot on the
host system which contains the downlink card. On SPARC Enterprise
M4000/M5000/M8000/M9000 servers, the hostpath has the following
format:
IOU#0-PCI#0 IO Board 0, PCI-E slot0
The External I/O Expansion Unit (box_id) is identified by serial number.
Use iox@nnnn, where nnnn represents the last four digits of the box serial
number.
Some commands affect only a single component of an External I/O
Expansion Unit system. For example, individual boats and power supplies
may be turned on and turned off independently.
A FRU in an External I/O Expansion Unit (fru) is identified as:
iox@nnnn/iob0 – I/O boat in the left tray (rear view)
iox@nnnn/iob1 – I/O boat in the right tray (rear view)
iox@nnnn/iob0/link – Uplink card in boat 0
iox@nnnn/iob1/link – Uplink card in boat 1
iox@nnnn/ps0 – Power supply in the left bay (front view)
iox@nnnn/ps1 – Power supply in the right bay (front view)
