HP 3PAR StoreServ 7450 Storage Troubleshooting Guide

5 Troubleshooting
The HP 3PAR OS CLI checkhealth command checks and displays the status of storage system
hardware and software components. For example, the checkhealth command can check for
unresolved system alerts, display issues with hardware components, or display information about
virtual volumes that are not optimal.
By default the checkhealth command checks most storage system components, but you can also
check the status of specific components. For a complete list of storage system components analyzed
by the checkhealth command, see “The checkhealth Command” (page 29).
The checkhealth Command
The checkhealth command checks and displays the status of system hardware and software
components.
Command syntax is: checkhealth [<options> | <component>...]
Command authority is Super, Service
Command options are:
• -list, which lists all components that checkhealth can analyze.
• -quiet, which suppresses the display of the item currently being checked
• -detail, which displays detailed information regarding the status of the system.
<component> is the command specifier, which indicates the component to check. Use the -list
option to get the list of components.
Using the checkhealth Command
Use the checkhealth command without any specifiers to check the health of all the components
that can be analyzed by the checkhealth command.
The following example displays both summary and detailed information about the hardware and
software components:
