Which PSTCLI command provides system health summary?

The health-check show command is the correct PowerStore Command Line Interface (PSTCLI) command used to retrieve and display a system health summary. This command presents the results from the most recently executed System Health Check, which assesses various hardware and software components of the PowerStore appliance. The output provides a consolidated view of the system's overall health status, making it the direct tool for obtaining a health summary as specified in the question.

A. system status: This is not a valid command in the PowerStore CLI. The system show command exists, but it displays general system properties like name and model, not a health summary.
B. svcdiag summary: This command is not part of the standard PSTCLI command set. It is typically associated with service-level scripts used by support personnel within the service shell, not for general administration.
D. alert list: This command provides a detailed list of all active and historical alerts on the system. It does not offer a consolidated health summary but rather a log of specific events.
