When adding a new drive to the cluster as part of the cluster expansion or field replacement procedure, the cluster checks the drive against a list of supported drives and raises an alarm if the new drive is not found on the list. Non-supported drives are rejected.
The list of drives that are compatible with the current VAST Cluster version is displayed in VAST Web UI in the Support -> Drive Compatibility page. For each drive, the page indicates the drive model name and number, supported firmware versions, capacity and role (boot drive, SSD, SCM). To view this information in VAST CLI, use the new supporteddrives list and supporteddrives get commands.
Drive compatibility information is maintained using a YAML file (provided and signed by VAST Support) that contains detailed information for the supported drives. This eliminates the need to run a cluster upgrade each time new drives are qualified to be used in VAST clusters.
YAML-based drive compatibility validation is enabled by default. If you want to have it disabled so that drives are verified against a hard-coded list initially supplied with the product, contact VAST Support.
