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.
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
Here is the storage configuration before Solaris Volume Manager is configured:
The SCSI controller/terminator pairs (cntn) have approximately 20 Gbytes of storage space.
Storage space on each disk (for example, c1t1d0) is split into seven partitions (cntnd0s0 through cntnd0s6).
To partition a disk, follow the procedures explained in Formatting a Disk in System Administration Guide: Devices and File Systems.
