Interpretation of netappp SP sensors output content

In the face of NetApp When doing fault diagnosis in the hardware environment , The frequently used command is environment status Or in sp In the environment system sensors, This article will give a detailed description of how to interpret the output results of these two commands .

stay Ontap Under the environment status The output of is actually a call SP Of sensors Output content .

SP sensor It's through threshhold-based To determine whether there is component There is a problem

System sensors     In the output system sensor Information about

System sensors get sensor_name You can get a more detailed one sensor Information about

One sensor Of reading The value is defined by the following judgment mechanism ：

• LCR     Lower Ciritcal
• LNC     Lower Noncritical
• UNC   Upper Noncritical
• UCR    Upper Critical

There are some sensors Without these four values , For something like this sensors,missing The value of is displayed as na

For System_Fw_status The interpretation of , The form of output content is 0xAABB, According to this AA and BB To judge sensor Of condition

AA It can be the following value :

01 System firmware error

02 System firmware hang

04 System firmware progress

BB It can be the following value :

00 System software has properly shut down

01 Memory initialization in progress

02 NVMEM initialization in progress (when NVMEM is present)

04 Restoring memory controller hub (MCH) values (when NVMEM is present)

05 User has entered Setup

13 Booting the operating system or LOADER

1F BIOS is starting up

20 LOADER is running

21 LOADER is programming the primary BIOS firmware. You must not power down the system.

22 LOADER is programming the alternate BIOS firmware. You must not power down the system.

2F Data ONTAP is running

60 SP has powered off the system

61 SP has powered on the system

62 SP has reset the system

63 SP watchdog power cycle

64 SP watchdog cold reset

for instance ：System_FW_Status sensor status 0x042F The meaning is "system firmware progress (04),

Data ONTAP is running (2F)."

System_watachdog The interpretation of

0x0080 The state of this sensor has not changed

0x0081 Timer interrupt

0x0180 Timer expired

0x0280 Hard reset

0x0480 Power down

0x0880 Power cycle

give an example ,System_Watchdog sensor status 0x0880 The meaning is watchdog timeout occurs and

causes a system power cycle.

PSU1_Input_Type and PSU2_Input_Type Reading

DC Power supply , This number is meaningless ,

0x01xx 220V PSU type

0x02xx 110V PSU type

NetApp Most of our storage systems are SP To monitor , But there are also some model Model is through BMC To monitor , stay BMC There are also corresponding commands , be called sensor show, The output is the same , As shown in the example below .

BMC yes sensor show
