  • Handling hibernation of a process on a storage device
    Patent number: 9002904
    Abstract: Migrating data from an old storage device to a new storage device includes creating new paths to the new storage device, freezing old paths to the old storage device, transferring metadata corresponding to the old storage device to the new storage device, where state information is transferred from the old storage device to the new storage device, and thawing the new paths. Migrating data from an old storage device to a new storage device may also include creating new volumes on the new storage device and transferring data from the old storage device to the new storage device. Migrating data from an old storage device to a new storage device may also include dismantling the old paths.

  • Porting replication relationships
    Patent number: 8600943
    Abstract: Migrating data from an old storage device to a new storage device includes transferring the data from a first logical device on the old storage device to a second logical device on the new storage device, determining replication relationships for the first logical device, transferring the replication relationships; and transferring logical devices used for the replication relationships from the old storage device to the new storage device. The replication relationships may include a clone of the first logical device. Migrating data from an old storage device to a new storage device may also include suspending writes to the first logical storage device prior to transferring the data for the first logical storage device. The replication relationships may include at least one snapshot.
