  • REMOTE ACTIVITY MONITORING
    Publication number: 20090077232
    Abstract: A computer readable medium and system for remotely monitoring activity includes generating first server heartbeat information at a first server at a local site, and storing the first server heartbeat information in a first primary site disk at the local site. The method also includes sending the first server heartbeat information from the first primary site disk, to a first secondary site disk at a remote site. The method further includes receiving information from a 10 second secondary site disk at the local site, and determining if the information received from the second secondary site disk includes updated heartbeat information.

  • Method and apparatus for providing multi-path I/O in non-concurrent clustering environment using SCSI-3 persistent reserve
    Patent number: 6954881
    Abstract: A method and apparatus for providing multi-path I/O in non-concurrent clustering environment is disclosed. Shared non-concurrent access to logical volumes through multiple paths is provided by using SCSI-3 persistent reserve commands. Open options of the operating system are mapped to SCSI persistent reserve commands to allow all of the multiple paths to register with the logical unit number of the shared storage system and to allow the second of the multiple paths to access the logical unit number of the shared storage system after obtaining a persistent reservation with the shared storage system.
