Preface As part of an improvement effort, revisions of the software and hardware are periodically released. Some functions that are described in this document are not supported by all versions of the software or hardware currently in use. The product release notes provide the most up-to-date information about product features. Contact your technical support professional if a product does not function properly or does not function as described in this document.
1 Introduction PowerStore includes service scripts that enable you to diagnose issues, solve common problems, perform certain operational tasks, and recover your system from an error state. These scripts provide in-depth level of information and a lower level of system control than is available through other interfaces such as PowerStore Manager, CLI, and REST API. This document describes these service scripts and how you can use them.
2 Service Commands This chapter contains the following topics: Topics: • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • Clear alerts (svc_alert) Shut down and reboot an appliance (svc_appliance) Capture array configuration data (svc_arrayconfig) Make space on the root partition (svc_cleanup) Clear firmware update (svc_clear_fw_update_alert) Shut down a SAN cluster (svc_cluster) Diagnose a create cluster failure (svc_cluster_diag) Cluster management (svc_cluster_management) Check
Alerts are typically cleared when the underlying problem has been resolved. However, some alerts might remain active even after the problem has been fixed due to a race condition, system crash, or other issue. An active alert can prevent some operations such as upgrading software or installing a patch.
