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.

Drive Identifier

c1t0d0 c1t3d0 c1t6d0 c1t9d0

c1t1d0 c1t4d0 c1t7d0 c1t10d0

c1t2d0 c1t5d0 c1t8d0 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.
