Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Feature Description

When Elastic Services Controller (ESC) uses Cinder Multi-Attach volume on Control Function (CF), Active and Standby for QvPC-DI, the invoked Openstack API version for virtual machine (VM) Orchestration is 2.60 or higher. In this API version, ESC encodes and injects the configuration files into the VM for security reasons. Since, the VM is unable to read the encoded configuration files, ESC uses the user_data compressed file. This user_data file contains the configuration files that are required to boot VM.
