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 (c n t n ) 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.

Initial Physical Storage Configuration

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

  • The SCSI controller/terminator pairs (c n t n ) have approximately 20 Gbytes of storage space.

  • Storage space on each disk (for example, c1t1d0) is split into seven partitions (c n t n d0s0 through c n t n d0s6).

    To partition a disk, follow the procedures explained in Formatting a Disk in System Administration Guide: Devices and File Systems .
