Sensor readings

speeding up commands by first recording status to a cache

Commands can take many seconds to run since even for subqueries the full SDR and SEL may be read. One can improve this considerably by first caching the whole SDR, and then having subsequent runs making use of the known structure by suplplying the -S sdr-cache-path option to ipmitool. Note that every invocation using this cache file will still give you the current numbers - the cache is not for the actual values, but for the structure.

ipmitool -I lanplus -H rmwn08 -U root -f /root/private/ipmi-pw sdr dump /root/ipmi-sdr.cache
   Dumping Sensor Data Repository to '/root/ipmi-sdr.cache'

ipmitool -I lanplus -H rmwn08 -U root -f /root/private/ipmi-pw -S /root/ipmi-sdr.cache sdr type temperature

The output of these commands has the following columns

1. IPMI sensor ID (16-character maximum)
2. IPMI sensor number
3. Sensor status, indicating which thresholds have been exceeded
4. Entity ID and instance
5. Sensor reading

Show temperature, voltage, and fan sensors

ipmitool -I lanplus -H rmwn01 -U root -f /root/private/ipmi-pw sdr elist full

Show all sensors of type temperature

ipmitool -I lanplus -H rmwn01 -U root -f /root/private/ipmi-pw sdr type temperature

Show information on all FRUs (Hardware serial numbers, etc.)

ipmitool -I lanplus -H rmwn01 -U root -f /root/private/ipmi-pw fru

Check/Change Power status

the chassis power accepts the commands status, on, off, cycle, reset, diag, soft

ipmitool -I lanplus -H rmwn03 -U root -f /root/private/ipmi-pw chassis power status

Reset the SP (the ILOM)

ipmitool  -H rmfs07 -U root -f /root/private/ipmi-pw mc reset cold

Turn on the locator LED. List LEDs and their values

This sets the locator LED to the FAST (4HZ) blink rate

ipmitool -E -I lan -H rmwn03 -U root -f /root/private/ipmi-pw sunoem led set sys.locate.led FAST LOCATE

One can list all the generic Devices that are controllable LEDs

ipmitool -I lanplus -H rmui01 -U root -f /root/private/ipmi-pw sdr list generic

List the value of the sun blade prepare_to_remove LED (but I found no way yet of setting this via IPMI)

ipmitool -I lanplus -H rmwn10 -U root -f /root/private/ipmi-pw sunoem sbled get OK2RM

Retrieve event logs

ipmitool -I lanplus -H rmwn03 -U root -f /root/private/ipmi-pw sel list
ipmitool -I lanplus -H rmwn03 -U root -f /root/private/ipmi-pw sel elist

Misc

Some IPMI readouts I had been asked to run during a problem investigation for SUN:

    # ipmitool -H localhost -U root -P  fru
    # ipmitool -H localhost -U root -P  sdr elist
    # ipmitool -H localhost -U root -P  sel elist
    # ipmitool -H localhost -U root -P  sunoem led get all
    # ipmitool -H localhost -U root -P  sensor list

Setting a node to boot from PXE or to boot into BIOS

ipmitool -I lanplus -H rmfs08 -U root -f /root/private/ipmi-pw chassis bootdev pxe

ipmitool -I lanplus -H rmfs08 -U root -f /root/private/ipmi-pw chassis bootdev bios

Platform Event Filtering (PEF) settings

ipmitool -I lanplus -H rmui01 -U root -f /root/private/ipmi-pw pef list
