NAME¶
usysident - operate device identification indicators
SYNOPSIS¶
/usr/sbin/usysident [-l <location_code> [-s normal|identify] [-t]]
/usr/sbin/usysident [-d <dev_name> [-s normal|identify] [-t]]
/usr/sbin/usysident [-V]
/usr/sbin/usysident [-h]
DESCRIPTION¶
The usysident utility is used to view and manipulate the indicators
(LEDs) that identify certain devices on IBM Power Systems servers. These
identifiers are specified by location code; location codes can be retrieved by
running lscfg.
When run without arguments, usysident will print a list of
all of the identification indicators on the system along with their current
status (on or off). The -l or -d options can be used to
specify a particular indicator, by location code or logical device name
respectively. If -l or -d is the only argument, the status of
that indicator will be printed. If the -s argument is specified in
addition, the indicator may be turned on or off.
OPTIONS¶
- -l location_code
- Specify the location code of the indicator.
- -d dev_name
- Specify the name of the device to be identified (e.g. eth0, sda).
- -s {normal|identify}
- Must be used with the -l or -d option; -s normal will
turn the indicator off, while -s identify will turn the indicator
on.
- -t
- Truncate the location code if necessary. If an indicator is not available
at the specified location, this option will continuously trim the last
clause off of the location code in an attempt to find an indicator near
the device.
- -V
- Display the version of the command and exit.
- -h
- Print the usage message and exit.
