Abstract
A system and method automatically generates a root volume for use by a storage operating system of a storage system. During initialization of the storage system, the storage operating system detects that no operational root volume exists and, in response, invokes a root volume generation process. The root volume generation process automatically creates a thinly provisioned flexible volume of the smallest allowable size on an aggregate. The created flexible volume is marked as the root volume for the storage system. The storage operating system then continues initialization utilizing the automatically generated root volume.
Claims30
A method for creating a new root volume for a storage system, comprising:
- executing an initialization routine for the storage system, the initialization routine failing because no operational root volume is associated with the storage system;
- and
- creating a new root volume using a flexible volume, the flexible volume created with a minimum size allowable by the storage system to initialize the storage system.
A system configured to create a new root volume for a storage system, the system comprising:
- means for executing an initialization routine for the storage system, the initialization routine failing because no operational root volume is associated with the storage system;
- and
- means for creating a new root volume using a flexible volume, the flexible volume created with a minimum size allowable by the storage system.
A system configured to create a new root volume for a storage system, the system comprising:
- a root volume creating process configured to, upon detection that no operational root volume exists, create a new root volume using a flexible volume, the flexible volume created with a minimum size allowable by the storage system, thereby allowing initialization of the storage system to continue using the created new root volume.
A method for creating a root volume for a storage system, comprising:
- scanning a set of storage devices associated with the storage system;
- determining whether a root volume is stored on the set of storage devices;
- in response to determining that no operational root volume is stored on the set of storage devices, creating a new volume as the root volume using a flexible volume, the flexible volume created with a minimum size allowable by the storage system to initialize the storage system;
- and
- completing initialization of the storage system using the new volume as the root volume.
A computer readable medium for creating a new root volume for a storage system, the computer readable medium including program instructions for performing the steps of:
- executing an initialization routine for the storage system, the initialization routine failing because no operational root volume is associated with the storage system;
- and
- creating a new root volume using a flexible volume, the flexible volume created with a minimum size allowable by the storage system to initialize the storage system.
A method for creating a new root volume for a storage system, comprising:
- identifying any aggregates as a root aggregate;
- where the aggregate includes a plurality of disks;
- in response to identifying the root aggregate, executing an initialization routing for the storage system, the initialization routine failing because there is not an operational root volume stored in the root aggregate;
- and
- in response to determining that there is not a root volume stored in the root aggregate, creating a new root volume using a flexible volume, the flexible volume created with a minimum size allowable by the storage system.
