Hot-relocation is a feature that allows a system to react automatically to I/O failures on redundant objects (mirrored or RAID-5 volumes) in VxVM and restore redundancy and access to those objects. VxVM detects I/O failures on objects and relocates the affected subdisks. The subdisks are relocated to disks designated as spare disks or to free space within the disk group. VxVM then reconstructs the objects that existed before the failure and makes them accessible again.
When a partial disk failure occurs (that is, a failure affecting only some subdisks on a disk), redundant data on the failed portion of the disk is relocated. Existing volumes on the unaffected portions of the disk remain accessible.
See "How hot-relocation works" on page 358.
