You can modify some of the properties for the cloud extensible attributes, except for the read-only attributes. By default, all cloud extensible attributes are configured to allow Read/Write access for the Cloud Platform Appliances. You can change this configuration to read-only so the Cloud Platform Appliances can only access the attribute values, but not modify them. Note that when you reference modification for a read-only attribute in a cloud API request, the Cloud Platform Appliance returns an error because it cannot modify the attribute value. For information about how to configure extensible attributes, see About Extensible Attributes.

Note: An  An upgrade could fail if the name of an existing extensible attribute matches the name of any of the cloud extensible attribute for a different object type. You must define values for all required cloud extensible attributes in a cloud API request.

Extensible Attributes for Tags in AWS and Azure

You can define metadata in the form of tags for AWS and Azure which are captured through a vDiscovery process and you can save the tags as extensible attributes in NIOS. You can use predefined attributes or create your own tags that consists of an user-defined key and an optional value. The tag values defined in AWS and Azure are translated into corresponding extensible attribute values in NIOS.

Note the following about saving tags defined in AWS and Azure as extensible attributes in NIOS:

• You must add extensible attributes in NIOS with the same name as the tags added in AWS or Azure.
• You can add or delete tags in Azure, but cannot update the tags.
• The tags are translated only when the corresponding extensible attributes are created in NIOS.
• The tags are discovered only during the next vDiscovery process after creating the corresponding extensible attributes in NIOS.
• It is not recommended to delete the extensible attributes which you have created for the tags defined in AWS and Azure.

The following table shows the translation of tags defined in AWS and Azure, as extensible attributes in NIOS:
