7 Monitoring storage system events
This chapter describes how to manage events using HP P6000 Command View.
Events overview
Events track the progress of actions, both normal and exceptional, that occur on the array. Examples
of typical events are creating virtual disks or initializing an array. Examples of exceptional events
are an incomplete function or a reduction in array capabilities. Normal events are more common
than exceptional events.
You can use HP P6000 Command View to configure and view these events. Managing events
from the HP P6000 Command View user interface is especially useful when you are monitoring
multiple arrays.
Events are captured in one or more of the following logs:
• Management server
• Controller
• Controller termination
All event logs are stored in the C:\Program Files\Hewlett-Packard\Sanworks\Element
Manager for StorageWorks HSV\cache\ directory on the management server (server-based
management only). There is a separate directory for each storage system that the management
server sees. Directories are named by storage system WWN.
For array-based management, click Capture System Information on the Server Options page to
capture the event logs and download them to the computer from which you are browsing.
Email notification
You can configure HP P6000 Command View to send email notifications regarding storage system
alarms and hardware conditions. For more information, see the online help.
Management server event log
The management server is the server on which HP P6000 Command View is installed. Management
server events are triggered by:
• Responses to user actions in the user interface
• Actions initiated through the HP P6000 Command View application program interface (API)
Controller event log
A controller event is a normal or exceptional action on any hardware component or logical object
within the array. Examples of controller events are:
• Disk or disk enclosure changes
• Configuration changes (such as creating a disk group)
• Controller reboots
• Changes detected by the environmental monitoring unit (EMU) within the array (does not apply
to the EVAx400 or P6000 models)
A normal event is informational and requires no action by you. An example of a normal event
would be the controller reporting that creation of a virtual disk has completed. An example of an
exceptional event would be a disk enclosure that has lost communication on a Fibre Channel loop.
CAUTION: Uninitializing an array deletes all of the controller events cached in the controllers.
