List all volumes in the VPSA storage array
AI agents call vpsa_list_volumes to retrieve information from Zadara Storage MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about volumes without creating, modifying, deleting, or executing any operations. It is a pure read operation with minimal blast radius if misused by an AI agent, as it only exposes existing storage configuration metadata.
From the tool's definition Tool name 'vpsa_list_volumes' and description 'List all volumes in the VPSA storage array' indicate a retrieval operation with no modification or deletion of data.
