Abstract
The present invention provides for a method and an apparatus for simultaneous online access of volume-managed data storage. A portion of a storage media to be mirrored is identified. An independent disk-mirror split-off process on the identified portion of the storage media to be mirrored is performed to produce a data mirror that is capable of being independently accessed.
Claims30
A method, comprising:
- identifing a portion of a storage media to be mirrored, said storage media being capable of storing data from a manufacturing tool;
- and
- performing an independent disk-mirror split-off process on said identified portion of the storage media to be mirrored to produce a data mirror that is capable of being independently accessed, said independent disk-mirror split-off process comprising:
- storing said identified portion of said storage media as a data mirror;
- and
- configuring said data mirror into a separate group to allow independent access of data in said data mirror, configuring said data mirror comprising causing said data mirror to become inactive and re-initializing said inactive data mirror into said separate group.
3 more elements
An apparatus, comprising:
- a computer system;
- at least one manufacturing tool coupled with said computer system, wherein said manufacturing tool is controlled by said computer system;
- a storage media coupled with said manufacturing tool, said storage media being capable of storing data from said manufacturing tool and generating a plurality of data mirrors of the stored data;
- and
- a volume manager coupled with said storage media and said computer system, said volume manager being capable of controlling said storage media and independently accessing at least one data mirror within said storage media.
2 more elements
An apparatus comprising:
- means for identifying a portion of a storage media to be mirrored, said storage media being capable of storing data from a manufacturing tool;
- and
- means for performing an independent disk-mirror split-off process on said identified portion of the storage media to be mirrored to produce a data mirror that is capable of being independently accessed, said means for performing said independent disk-mirror split-off process comprising:
- means for storing said identified portion of said storage media as a data mirror;
- and
- means for configuring said data mirror into a separate group to allow independent access of data in said data mirror, said means for configuring said data mirror comprising means for causing said data mirror to become inactive and means for re-initializing said inactive data mirror into said separate group.
3 more elements
A computer readable program storage device encoded with instructions that, when executed by a computer, performs a method, comprising:
- identifying a portion of a storage media to be mirrored, said storage media being capable of storing data from a manufacturing tool;
- and
- performing an independent disk-mirror split-off process on said identified portion of the storage media to be mirrored to produce a data mirror that is capable of being independently accessed, said independent disk-mirror split-off process comprising:
- storing said identified portion of said storage media as a data mirror;
- and
- configuring said data mirror into a separate group to allow independent access of data in said datd mirror, configuring said data mirror comprising causing said data mirror to become inactive and re-initializing said inactive data mirror into said separate group.
3 more elements
An apparatus, comprising:
- a storage media for storing data, said storage media being capable of storing data from a manufacturing tool;
- and
- a controller operatively coupled to said storage media, said controller to identify a portion of said storage media for storage as a data mirror and to configure said data mirror into a separate group by inactivating and re-initializing said data mirror to allow independent access of data in said data mirror.
