Cabling the RAID Subsystem Cluster Components

This chapter provides the procedures for interconnecting two HP host servers and a shared StorageWorks RAID subsystem through the SCSI bus, and externally terminating the bus as applicable. Interconnection procedures for locating the RAID subsystem in a Mid-Bus, Hub-Radiant and End-Bus layout are provided, based upon the basic cluster layout selected in Chapter 1.

2.1Connecting RAID Subsystem Components through the SCSI Bus

Based on the basic RAID cluster (SCSI bus) layout option you have selected, locate the procedures in this section (cross-referenced in Chapter 1, Table 1-1of this guide), to cable and terminate the cluster components through the SCSI bus. When you have finished, reboot all the servers in the cluster.

NOTES

∙The following procedures assume that the SCSI host adapters have been prepared (e.g., on- board resistor packs removed and SCSI IDs set) as described in Chapter 1.

∙For clarity in Figures 2-1 through 2-3, the VHDCI SCSI cables and terminators are shaded and the HD68-pin (fast, wide SCSI) components are white.

∙Cables and terminators supplied with your RAID subsystem supplement the components in your RAID SCSI Connection Kit. (See Chapter 1, Table 1-2).
