ABSTRACT:
A method for transferring sets of mirrored disks from an active system to a standby system in the event of a failure of the active system, wherein each of the computer systems maintains a table containing entries that reflect the state of sets of mirrored disks attached to that system, comprises merging the entries of the table of the failed system with the entries of the table of the standby system to create a merged mirror information table on the standby system. A connection to the mirrored sets of the failed system can then be switched to the standby system, and the mirrored sets then brought on-line on the standby system in accordance with information in the merged table.
