System Administration 91
list [
target
]
Lists the External I/O Expansion Units under system management.
If no target is specified,
list
displays a list of External I/O Expansion Units,
one per line. Each line contains the unique identifier for that box and the
host-specific name(s) for its downlink card(s). See EXAMPLE 3.
If an External I/O Expansion Unit argument or downlink card path is
specified, the command displays a single line with the indicated FRU. If a
host
path is specified, only the downlink card information is displayed. If the
verbose option [
-v
] is set, the output includes detailed FRU information. See
EXAMPLEs 4 and 5.
locator [on |off] [
target
]
Sets or queries the state of the locator indicator (LED).
Without options,
locator
reports the current state of the LED on the
specified FRU.
A target argument is required when using the
on
or
off
field:
on
Turns the LED on.
off
Turns the LED off.
The chassis locator is a white LED. If a FRU is specified, the FRU yellow
service LED is used along with the chassis (locator) LED.
Only one FRU can have a location indicator enabled at a time in an External
I/O Expansion Unit chassis. Turning off the chassis (locator) LED will also
turn off the blinking (service) FRU LED. See EXAMPLEs 10, 11 and 12.
poweroff
target
Powers down the given FRU and lights appropriate LEDs to indicate the FRU
is ready to remove. Must be used with the
-f
option. Be aware that using
-f
can crash the domain.
Do not remove both power supply units (PSUs) in the same External I/O
Expansion Unit. If both PSUs are powered down in this way, then the
External I/O Expansion Unit cannot be turned back on from the command
line. It must be powered on physically.
Note –
When a power supply is powered off, the LEDs and fan may still run
since they receive power from both supplies.
