  • Patent number: 9985873
    Abstract: A data storage system provides asymmetric multi-path access to a storage device from a host computer using a storage protocol such as SCSI. Device state information is maintained indicating that one path of set of paths between the host computer and the storage device is a non-fully-functional path. In response to receiving device discovery commands from the host computer on the one path and the one path being indicated to be a non-fully-functional path, the data storage system returns respective good responses indicating that the storage device is accessible to the host computer via the non-fully-functional path. However, in response to receiving a test unit readiness command from the host computer on the one path and the one path being indicated to be a non-fully-functional path, an error response is returned which causes the host computer to select an alternative path of the set of paths for the data transfer.

  • Patent number: 8880821
    Abstract: Determining whether to migrate from a source storage device to a target storage device includes determining if the target storage device is accessible by hosts that access the source storage device, determining if reservation information stored on the target storage device matches reservation information stored on the source storage device and migrating from the source storage device to the target storage device if the target storage device is accessible by hosts that access the source storage device and reservation information stored on the target storage device matches reservation information stored on the source storage device. Determining whether to migrate from a source storage device to a target storage device may also include, in response to initially determining that the reservation information stored on the target storage device does not match the reservation information stored on the source storage device, attempting to match the reservation information.
