Solution Type Problem Resolution Sure Solution 1004680.1 : Sensor status warning messages on Sun Fire[TM] (3800-6800)systems
PreviouslyPublishedAs 206486 Symptoms What does "sensor status under limit" or "sensor status over limit" mean? Resolution This means that a temperature or voltage threshold has been exceeded. The text surrounding this status message, point to the component that is having the problem. Unless there is a thermal problem in the environment or power problems, the system board identified with the "sensor status" problem should be replaced. NOTE: These messages are usually decoded for you by Scapp. This information is provided for those instances where not all the messages may be available (e.g. high security black sites). This is current as of Scapp release 5.11.4. The numerical message format is: event type, event code, sensor tag Where event type is 7 for environmental events. The event codes for environmental events are: 1 sensor over limit 2 sensor under limit 3 sensor shutdown - environmental shutdown has occurred 4 fan failure 5 fan is ok again The sensor tag bitfields are defined as: +------------------------------------------------------- HPU Type | +---------------------------------------------- Slot | | +-------------------------------------- Part | | | +----------------------------- Part # | | | | +---------------------- Type | | | | | +-------------- Type num | | | | | | +-------- Node ID | | | | | | | +-- Reserved | | | | | | | | 63 ... 48 47..40 39..32 31..24 23..16 15..8 7..4 3..0 The HPU Type is encoded as: 0x101 4800, 4810, 6800 SC 0x102 3800 SC 0x201 CPU Board 0x301 4800, 4810, 6800 Fireplane Switch 0x303 3800 Fireplane Switch 0x401 6800 I/O Fan Tray 0x402 6800 CPU Fan Tray 0x403 Rack Fan Tray 0x404 4800 Fan Tray 0x405 4810 I/O Fan Tray 0x406 4810 CPU Fan Tray 0x407 4800 Top Fan Tray 0x408 3800 Fan Tray 0x409 4800 Bottom Fan Tray 0x501 4800, 4810, 6800 PCI I/O Assembly 0x502 4800, 4810, 6800 cPCI I/O Assembly 0x503 3800 cPCI I/O Assembly 0x60x Power Supply Where the Part is encoded as: 0x1 SBBC 0x2 SDC 0x3 AR 0x4 CBH 0x5 DX 0x6 CHEETAH 0x7 1_5_VDC 0x8 3_3_VDC 0x9 5_VDC 0xA 12_VDC 0xB 48_VDC 0xC CURRENT 0xD BOARD 0xE SCAPP 0xF SCHIZO 0x10 FAN And the (Sensor) Type is encoded as: 0x1 VOLTAGE 0x2 CURRENT 0x3 TEMPERATURE 0x4 COOLING 0x5 1_5_VDC 0x6 1_8_VDC 0x7 3_3_VDC 0x8 5_VDC 0x9 12_VDC 0xA 48_VDC 0xB ENVDB Therefore, the following example would decode as follows: Sensor Status OverLimit /N0/SB0 7,1,Ox201000601060100 0x201 - CPU Board 0x00 - Slot 0 0x06 - Cheetah 0x01 - Cheetah #1 (i.e. CPU 1) 0x06 - 1.8V DC sensor 0x01 - Sensor #1 on Cheetah 0x0 - Node 0 Thus, the 1.8 voltage level is over the limit on CPU 1 on SB 0 for this example.
