System and method for initializing a network attached storage system for disaster recovery
First Claim
1. A method for initializing a mirrored Network Attached Storage (NAS) system for disaster recovery, wherein the mirrored NAS comprises a source NAS comprising a plurality of source components and a target NAS comprising a plurality of target components, the source NAS and target NAS being coupled via a communication link, the method including the steps of:
- the target NAS querying the source NAS via the communication link to obtain configuration information for the source NAS; and
the target NAS initializing the mirrored NAS for disaster recovery in response to the configuration information.

Abstract
A method and system for initializing a Network Attached Storage (NAS) system having disaster recovery capabilities uses a communication link disposed between control stations of a source and destination NAS to enable the destination NAS to consolidate configuration and mapping information at a centralized location, thereby enabling validation of disk mirroring and mapping of standby components to be performed in a consistent manner.

10. A control station coupled to a remote Network Attached Storage (NAS) comprising:
-
an interface for establishing a communication link with control stations of a source NAS; means for retrieving source configuration information from the source NAS, means for retrieving remote configuration information from the remote NAS; initializing disaster recovery relationships between the source NAS and the remote NAS in response to the source configuration information and the remote configuration information, the step of initializing including validating device mappings and identifying standby candidate servers at the remote NAS to associate with for servers in the source NAS. - View Dependent Claims (11, 12, 13)
