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.

Manual Pre-Upgrade Validations

Overview

This section describes the manual pre-upgrade validations if you are unable to run the Hypercheck Health Check described in Hypercheck: Pre-Upgrade Check Tool. Running Hypercheck is highly recommended over performing these checks manually.

Checking Cluster Storage Capacity

Cisco recommends that you check the cluster storage capacity before starting the upgrade of an existing installation of Cisco HX Data Platform. If the storage utilization in the cluster is above 70%, the upgrade validation fails.

When storage utilization in the cluster is above 70%, an offline upgrade is recommended.

Refer to the HX Storage Cluster Overview chapter in the Cisco HyperFlex Data Platform Administration Guide for background details about checking cluster storage capacity.
