Solution Type Technical Instruction Sure Solution 1003658.1 : Sun Fire[TM] V210 and Sun Fire[TM] V240 Voltage sensors defined
PreviouslyPublishedAs 205169 Description Both the "showenvironment" command from the ALOM prompt and the "prtdiag -v" command from Solaris[TM] display the status of certain voltage levels of a running Sun Fire[TM] V210 or Sun Fire[TM] V240 system. When troubleshooting a failing system it can be useful to know what the voltages being monitored by these sensors are used for. Steps to Follow The values of various voltage lines for the V210 and V240 can be found in two places. Either by issuing the "showenvironment" command from the ALOM prompt, or by executing the "prtdiag -v" command from Solaris. Being able to monitor these values can be a valuable troubleshooting tool when trying to track down the cause of a problem on these systems. If we see that one of these voltages is either too high or too low it may shed some light on what functionality of the system we may experience issues with. Of course for these values to be of any use we need to know what the voltage being reported is used for. It can mean the difference in knowing that the system requires a simple battery replacement, or the need for an entire motherboard replacement. Here are examples of what you should expect to see reported from the two commands that report this information. (please note that with different ALOM firmware versions and different Solaris OS and patch revisions these outputs may appear slightly different from what is shown here) example of the ALOM "showenvironment" command's Voltage section ==>> -------------------------------------------------------------------------------- Voltage sensors (in Volts): -------------------------------------------------------------------------------- Sensor Status Voltage LowSoft LowWarn HighWarn HighSoft -------------------------------------------------------------------------------- MB.P0.V_CORE OK 1.45 -- 1.26 1.54 -- MB.P1.V_CORE OK 1.46 -- 1.26 1.54 -- MB.V_VTT OK 1.30 -- 1.17 1.43 -- MB.V_GBE_+2V5 OK 2.50 -- 2.25 2.75 -- MB.V_GBE_CORE OK 1.20 -- 1.08 1.32 -- MB.V_VCCTM OK 2.53 -- 2.25 2.75 -- MB.V_+2V5 OK 2.62 -- 2.34 2.86 -- MB.V_+1V5 OK 1.51 -- 1.35 1.65 -- MB.BAT.V_BAT OK 2.98 -- 2.70 -- -- example of the Solaris "prtdiag -v" command's Voltage section ==>> --------------------------------------------------------- Voltage sensors: ------------------------------------- Location Sensor Status ------------------------------------- MB/P0 V_CORE okay MB/P1 V_CORE okay MB V_VTT okay MB V_GBE_+2V5 okay MB V_GBE_CORE okay MB V_VCCTM okay MB V_+2V5 okay MB V_+1V5 okay MB/BAT V_BAT okay PS0 P_PWR okay PS0 FF_POK okay PS0 FF_UV okay PS0 FF_OV okay PS1 P_PWR okay PS1 FF_POK okay PS1 FF_UV okay PS1 FF_OV okay ------------------------------------ here are the definitions of each sensor: MB.P0.V_CORE - core voltage rail for processor 0 MB.P1.V_CORE - core voltage rail for processor 1 MB.V_VTT - Memory termination voltage rail MB.V_GBE_+2V5 - Gigabit Ethernet controller 2.5V rail MB.V_GBE_CORE - Gigabit Ethernet controller 1.2V rail MB.V_VCCTM - 2.5V rail voltage for the Tomatillo PCI bridge MB.V_+2V5 - Motherboard +2.5V rail MB.V_+1V5 - Motherboard +1.5V rail MB.BAT.V_BAT - voltage supplied by 3v battery The last six entries listed in the prtdiag output are status reports of the power supplies that are installed: PS0 P_PWR - power supply 0 power inlet presence PS0 FF_UV - power supply 0 under voltage PS0 FF_OV - power supply 0 over voltage PS1 P_PWR - power supply 1 power inlet presence PS1 FF_UV - power supply 1 under voltage PS1 FF_OV - power supply 1 over voltage Product Sun Fire V240 Server Sun Fire V210 Server Voltage, sensors, showenvironment, prtdiag Previously Published As 81356 Change History Date: 2010-05-24 User name: Anthony Rulli Action: reviewed Comments: Currency check, audited by Dencho Kojucharov, Entry-Level SPARC Content Lead emailed Author concerning missing keyword statement My name is Kinsey, I am a Knowledge Engineer working on post Voyager cleanup. I came across your article, it is a frequently used article. In order for me to be able to publish I will need a subject matter expert to add a Keywords Statement. This statement is necessary for searchability. I will return this article to Tech Review where you should be able to pick it up and add this statement.
