Monitoring and managing devices

Introduction to monitoring and managing devices

HP provides many tools for managing your IO Accelerator devices. These tools allow you to monitor the devices for errors, warnings, and potential problems. They also allow you to manage the devices, including performing the following functions:

•Firmware upgrades

•Low-level formatting

•Attach and detach actions

•Device status and performance information

•Configuring Swap and Paging

•Generating bug reports

Management tools

HP has provided tools for monitoring and managing IO Accelerator devices. These include stand-alone tools that require no additional software and a data-source tool that can be integrated with other applications.

Consider the descriptions of each tool to decide which tool (or combination of tools) best fits your needs.

About error messages

The IO Accelerator VSL software prints some error messages to the system logs. While these messages are useful for troubleshooting purposes, the VSL log messages are not designed for continual monitoring purposes (as each is based on a variety of factors that could produce different log messages depending on environment and use case). For best results, use the tools described in this section to regularly monitor your devices.

Stand-alone tool

These stand-alone tools do not require any additional software.

Command-line utilities: These utilities are run manually in the terminal. The fio-statusutility provides status for all devices within a host. The other utilities allow you to perform other management functions. For more information, see "Utilities (on page 22)."

iData-source tool

This data-source tool provides comprehensive data, like the stand-alone tools, but it requires integration with additional software. At a minimum, it can interface with a browser. However, the benefit of this tool is that it can be integrated into existing management software that is customized for your organization.

This tool is available as a separate download. For more information, see the IO Accelerator release notes.

SNMP Subagent: The SNMP AgentX subagent allows you to monitor and manage your ioMemory devices using the Simple Network Management Protocol. You can use a normal SNMP browser or customize your existing application to interface with the subagent.
