Abstract
A method includes receiving a first command for accessing a tape storage system, the first command containing an indicator that the first command was issued as a result of a failover from a first path to the storage system to a second path to the tape storage system. The method further includes determining whether the first command is a repeat of a second command already received by the tape storage system. The first command is processed based on determining whether the first command is a repeat of the second command.
