System Management Guide: Operating System and Devices

Changing or Removing a Paging Space

This procedure describes how to change or remove an existing paging space.

Attention: Removing default paging spaces incorrectly can prevent the system from restarting. This procedure is for experienced system managers only.

Note: You must deactivate the paging space before you can remove it. A special procedure is required for removing the default paging spaces (hd6, hd61, and so on). These paging spaces are activated during boot time by shell scripts that configure the system. To remove one of the default paging spaces, these scripts must be altered and a new boot image must be created.
