Volume group structure recovery in a virtualized server recovery environment

摘要

A method and system for automatically performing a volume group structure recovery in a virtualized server recovery environment. A first portion of a first physical volume is accessed and then stored in a temporary file. A last valid volume group backup for a volume group is retrieved. The volume group is a logical group of physical volumes that include the first physical volume. The volume group backup includes respective volume group identifiers corresponding to the physical volumes of the volume group. An existing volume group identifier is replaced with a generated random volume group identifier. Volume group identifiers in the last valid volume group backup is replaced with new volume group identifiers that were generated during a re-initializing of all physical volumes in a list of the physical volumes of the logical group. The volume group's volume group structure is restored using a backup structure stored in the temporary file.
