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.
