USYSIDENT(8) Linux on Power Service Tools USYSIDENT(8)NAMEusysident - 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]
DESCRIPTION
The usysident utility is used to view and manipulate the indicators
(LEDs) that identify certain devices on PowerPC-64 machines. 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 continu‐
ously trim the last clause off of the location code in an
attempt to find an indicator near the device.
