-v Verbose (only on cellular systems). For status checks, prints out the components and connectivity of the running partition. hpuid-Reports Unique Identifier (UID) Syntax /sbin/hpuid [-d] [-e] [-s] [-v] The Unique Identifier (UID) is a flashing LED on the chassis used to identify a box. This identifier can be a great aid when you are confronted with a server farm of hundreds of boxes. On entry-level systems, the UID is a blue LED that is present on both front and rear panels. The LED is also a push-button, which toggles the state of the LED. The current state of the UID can be read or changed with the hpuid command. On midrange and high-end systems (cellular/partitioned platforms) there is no push-button. The UID is not a single LED but a collection of all LEDs for the components of the running partition. Thus if there was a partition that consisted of one cell in cabinet 0, one cell in cabinet one, and one I/O chassis in cabinet 8, the UID consists of the following: • The three large digits on the cabinet doors • The Attention LED of each cell board • The Attention LED of the I/O chassis (located on the Bay panel) hpipmid-Caches IPMI Data Syntax hpipmid [-f -h -v] The daemon is started by the /etc/init.d/hpmgmtbase script during normal boot operation and should not be run manually. hpipmid manages several features related to chassis events. • When the SEL is full, no further events can be written. hpipmid monitors the capacity, clearing the SEL when necessary. This operation is much more complicated in a cellular complex where every partition shares the same SEL. • The daemon pulses the IPMI watchdog timer, which shows up as heartbeat activity on the MP Virtual Front Panel (VFP) for midrange and high-end systems. In addition, hpipmid caches IPMI data (logs, data, and sensor readings) and provides information to client programs, such as SNPM agents or WBEM providers. hpbmc-Manages the IPMI BMC on HP Integrity Servers Syntax /sbin/hpbmc [-d path] [-b busaddr] [directives [ data ]] hpbmc is a general-purpose utility that provides complete access to the BMC. Its primary command argument is one of a list of directives that expose a particular feature of the BMC (for example, SELprint lists the current contents of the System Event Log). There are open source tools available that have similar functionality, such as ipmitool (found at http://ipmitool.sourceforge.net and shipped with some commercial distributions). hpbmc provides more functionality than those tools by handling the OEM IPMI extensions of HP Integrity Servers. See hpbmc(8) or Appendix B (page 20) for a complete explanation of all directives. This section discusses some of the background processing done by hpmgmtbase and hpbmc. hpuid-Reports Unique Identifier (UID) 11
