Appendix B Using a Standalone JBOD Array (SANnet II 200 FC Array Only) B-7

In this example, if the loop ID switch is set to 0, the format command shows 12
drives on this loop, ranging from c1t0d0 to c1t11d0.
The drive identifiers are arranged in four columns of three drives each to reflect the
physical location of these drives in the JBOD. They correspond to the locations of
Disk 0 through Disk 11.
B.7.2 Dual-Port Connections to a SANnet II 200 FC
JBOD Array
You can also connect a SANnet II 200 FC JBOD array to both ports on a dual-port
HBA, ports on two single-port HBAs, or a port on a single-port HBA and a single port
on a dual-port HBA.
Use host-based multipathing software such as VERITAS DMP 3.2 or 3.5 software to
manage SANnet II 200 FC JBOD arrays connected to a host over more than one loop.
Multipathing software provides full services on multiple paths between the server and
the storage system.
