Linux – “HDD Status” in ipmitool sensor output

ipmiipmitoollinuxsupermicro

I have a Supermicro "SuperServer 1028U-TR4+" box (motherboard: X10DRU-i+).

I use command

ipmitool -H <ipmi_ip> -U <ipmi_user> -P <ipmi_password> sensor

and get this output:

...
Chassis Intru | 0x0 | discrete | 0x0000| na | na | na | na | na | na
PS1 Status | 0x1 | discrete | 0x0100| na | na | na | na | na | na
PS2 Status | 0x1 | discrete | 0x0100| na | na | na | na | na | na

HDD Status | 0x1 | discrete | 0x0100| na | na | na | na | na | na

What does "HDD Status" mean? I can not find documentation on it.

Also, i see the short switching of this sensor to 0
periodically. I want know what this means.

ipmitool might use sensor number and sensor name for command output. You can use the following command to print the command output in a more friendly format: 

ipmitool -H <ipmi_ip> -U <ipmi_user> -P <ipmi_password> sdr elist

This will output all sensor names in your server mapped to the corresponding sensor numbers.

As can be seen from the output you posted, HDD status checks if drive/s is/are present and if the status is ok:

HDD Status | 54h | ok | 4.1 | Drive Present

In the output: the sensor name is in the first column and the corresponding sensor number is in the second column.

For a very detailed info, you can try running:

ipmitool -H <ipmi_ip> -U <ipmi_user> -P <ipmi_password> sdr -v

Here is a link to some very useful ipmitool commands:

Although the page is in german, but commands and explanations are in english, so it should not be too difficult to read it I hope ;)
