Abstract
Official abstract text for this publication.
Systems and methods which provide mount catalogs to facilitate rapid volume mount are shown. A mount catalog of embodiments may be provided for each aggregate containing volumes to be mounted by a takeover node of a storage system. The mount catalog may comprise a direct storage level, such as a DBN level, based mount catalog. Such mount catalogs may be maintained in a reserved portion of the storage devices containing a corresponding aggregate and volumes, wherein the storage device reserved portion is known to a takeover node. In operation according to embodiments, a HA pair takeover node uses a mount catalog to access the blocks used to mount volumes of a HA pair partner node prior to a final determination that the partner node is in fact a failed node and prior to onlining the aggregate containing the volumes.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: storing a mount catalog in association with one or more volumes of a first data storage sub-system, wherein the mount catalog comprises direct storage level based information facilitating access to volume information blocks of storage media of the first data storage sub-system without bringing an aggregate of the storage media of the first data storage sub-system containing the one or more volumes online; and accessing the volume infor…
