Sun Cluster 3.0-3.1 With SCSI JBOD Storage Device Manual for Solaris OS

SPARC: Dual-SCSI-Port Hosts

To cable the storage arrays correctly, adhere to the bus-length restrictions that are listed in the documentation that shipped with your host adapter. In a Sun Cluster environment, this cable-length measurement includes the cables to both nodes. This cable-length measurement also includes the bus length that is internal to each storage array, node, and host adapter.
