Solaris Volume Manager Administration Guide

Scenario Background Information

Throughout this book, the scenarios and many of the examples relate to a single configuration. Although this configuration is small (to simplify the documentation), the conceptsl scale to much larger storage environments.

Hardware Configuration

The hardware system is configured as follows:

  • There are three physically separate controllers (c0 – IDE, c1 – SCSI, and c2 – SCSI).

  • Each SCSI controller connects to a MultiPack that contains six internal 9-Gbyte disks (c1t1 through c1t6 and c2t1 through c2t6). This creates a mirror configuration.

  • Each controller/terminator pair (cntn) has 8.49 Gbytes of usable storage space.

  • Storage space on the root (/) drive c0t0d0 is split into six partitions.

An alternative way to understand this configuration is shown in the following diagram.

Figure 5-1 Basic Hardware Diagram Storage Scenario
Diagram shows system with three controllers and attached disks. Two controllers have six disks and the third has a single disk with the root slice.

Initial Physical Storage Configuration

Here is the storage configuration before Solaris Volume Manager is configured:
