Computer system and its event notification method

摘要

If a failure occurs in physical resources constituting a virtual volume, a management server device is notified of information required by a user. A computer system includes a server device for managing a plurality of virtual volumes, a storage apparatus having a storage unit equipped with a plurality of storage devices, and a controller for controlling data input to, or output from, the storage unit, a management server device which is an access target of a user terminal, and an event management device for managing an event(s) generated by the server device or the storage apparatus, wherein when the event management device receives the event, it judges the content of the event and identifies a virtual volume to be affected by the event; and if a service level that should be satisfied by the identified virtual volume is defined for the identified virtual volume, the event management device identifies, based on the content of the received event, whether an incident in violation of the service level has occurred or not, and then notifies the management server device of the identified content as an event based on an event filter.

1. A computer system comprising:
a storage apparatus for controlling data input to, or output from, one or more storage devices and generating an event when a failure occurs in at least one of a plurality of physical resources used for the control; one or more server devices for managing a plurality of virtual volumes, which are obtained by virtualizing a plurality of real volumes composed of a storage area of the storage device, and for generating an event when a failure occurs in at least one of a plurality of physical resources used for the management; a management server, allocated to each of one or more domains, for managing a plurality of virtual volumes exclusively used by a virtual machine that belongs to one of the domains, the management server displaying a received message on a management terminal; and an event management device for managing at least the storage apparatus or the server device as a management target and managing an event generated by the management target; wherein when receiving the event from the management target, the event management device judges the content of the received event and identifies a virtual volume to be affected by the generation of the event based on event information including the content of the failure of the physical resource associated with the identified virtual volume, identifies managing the identified virtual volume, and a domain is identified and its management server is identified; andif a service level that should be satisfied by the identified volume is defined for the identified virtual volume, the event management device identifies, based on the content of the received event, whether an incident in violation of the defined service level has occurred or not, and notifies the identified management server device of the identified as an event based on an event filter.
