How to determine system_id？ #30

Closed jyokako closed 3 years ago

jyokako commented 3 years ago

For example , In order to get Chassis information, we need to know the system_id of each vendor's server. As shown below.

Cloud you tell me how to set the system_id in you program, or is it to determine the system_id (System.Embedded.1 or 1) automatically?

Hello, Basically I grab all required information via a upstream lib called https://github.com/stmcginnis/gofish.

for chasis, each one has an ID, and it mapped via this lib, you can get more insight within this lib

The Redfish schema does not define how these IDs should be formatted or assigned. That is up to each implementation to decide. As you show, HPE chose to use the longer name of System.Embedded.1, while Dell is more concise with just the ordinal number of 1.

These are accessed via the Service Root. That has a Chassis field that links to any Chassis's managed by this Redfish service. So there is no way to predetermine what those will be named without querying the service root to get this list. Though it does seem vendors are at least consistent across their product lines, so once you know what they use, it's easy to guess what the IDs will be from system to system.

@jenningsloy318 @stmcginnis Thank you for your detailed answer. I was able to understand how it works. I would implement this source code and check the details . This case will be closed.
