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.

Method and system for a failover procedure with a storage system

The present disclosure relates to a system and method for detecting devices connected to a network. The method comprises sending a scan request to a remote command process running on a remote network host, scanning the network host with the remote command process to determine if devices are connected to the host, and receiving a response to the scan request from the remote command process that indicates whether a device is connected to the network host. In a preferred arrangement, the remote command process sends a scan request to a host application program interface to receive device addresses. With these addresses, the remote command process requests information from the devices.
