Introduction

A fault domain consists of one or more ESXI hosts and Datastore Clusters grouped together according to their physical location in the datacenter. 

The following table shows a brief description and HTTP methods allowed to interact with Fault Domains.

Remember, you can also show what methods are allowed and method description, parameters, etc. by making an OPTIONS HTTP request to /v2/domain.

TK stores the Cloud API Token generated as a result of the following POST request to the /auth/request-token resource:

Code Block
curl -X POST https://vss-api.eis.utoronto.ca/auth/request-token -u <username>

For example, extracting the token with the jq command:

Code Block
TK=$(curl -X POST https://vss-api.eis.utoronto.ca

...

/

...

auth/request-token -u <username> | jq -r '.token')

List

In order to list allowed Fault Domains you should make a GET request to the endpoint /v2/domain passing your access token. As a result, you will get a reference URI /v2/domain/<moref> to get detailed information about that domain, human readable name and Managed Object Reference (moref).

List specific Fault Domain Info

Some of the attributes will have an object value. Such is the case of items in attribute vms.

Name

Type

Description

name

string

Fault Domain name.

moref

string

vCenter Managed object reference.

status

string

Fault Domain general "health" value:

  • gray: The status is unknown.

  • green: The entity is OK.

  • red: The entity definitely has a problem.

  • yellow: The entity

...

  • might have a problem.

vms

array

Array of Virtual Machines hosted in given fault domain.

The following example, requests information about a particular Fault domain using the base resource /v2/domain and appending the moref to get the URI /v2/domain/domain-c5877:

Code Block
http

...

 GET https://vss-api.eis.utoronto.ca

...

/v2/domain/domain-c5877?summary=1 "Authorization: Bearer $TK"
curl -H "Authorization: Bearer $TK" -u $TK -X GET https://vss-api.eis.utoronto.ca

...

/v2/domain/domain-c5877?summary=1
