NAME
hpuid — hp Unique IDentifer (UID) utility
Synopsis
/sbin/hpuid [-d] [-e] [-s] [-v]
Description
hpuid interacts with the "Unique
IDentifier" (UID) LED on HP Integrity servers, turning it on and
off or reporting its current status.
Entry-level servers have a blue LED on the front
and back panels; this redundant pair of LEDs is the UID. For midrange
and high-end servers, each major component of the complex (cabinets,
cells, and IO chassis) has its own LED. The UID is the collection
of LEDs for all components that make up the running partition.
- -d
Disables the UID; blinking
stops and each LED goes to its quiescent state, typically an unlit
LED. On partitioned servers, the cabinet LED is a large digit in
the doors whose quiescent state is "on" and not blinking.
- -e
Enables the UID; blinking
starts.
- -s
Prints the status of the
UID to standard output:
OFF - The UID is
not blinking.
BLINKING - The UID
is blinking.
UNKNOWN - The status
is not available on this server. Retry hpuid -e, also using the -v option to get
more details.
PARTIALLY - A modifier
on cellular systems if some, but not all, LEDs in the UID collection
are blinking.
- -p
Displays system product
name.
- -r
Displays system product
version.
- -s
Displays system serial
number
- -v
Verbose (only on cellular
systems). For status checks, prints out the components and connectivity
of the running partition.
Environment Variables
hpuid will use the target in HPBMC_DEVICE, whether a local device file or RMCP
destination (see hpbmc(8) for format). This only works
for entry-level HP Integrity servers, and the status option cannot
be used.
Files
A character device file and the driver behind
it are managed by the configuration of the hpmgmtbase package which also provides hpuid.
