By default, the Solaris 9 9/02 installation program places swap starting at the first available disk cylinder, which is typically cylinder 0. This placement provides maximum space for the root (/) file system during the default disk layout and enables the growth of the root (/) file system during an upgrade.
If you think you will need to expand swap space in the future, you can place the swap slice so that it starts at another disk cylinder by using one of the following methods.
For the SolarisTM Web Start and SunInstallTM installation programs, you can customize the disk layout in cylinder mode and manually assign the swap slice to the desired location.
For the Solaris Custom JumpStartTM installation program, you can assign the swap slice in the profile file.
If you are creating a mirrored root (/) file system, see "Solaris Volume Manager metattach Command Might Fail".
For more information on the Solaris Custom JumpStart profile file, see the Solaris 9 Installation Guide.
